[Question]
[
Something I found while looking through some old files. It seemed like a neat idea for a code golf challenge.
## The intro
One of the most popular events at the annual Cyclist's Grand Competition for Charity (CGCC) is the rocket bike parcours. The rules are simple: Inspect the parcours and place a bet on wheather is it possible to reach and exactly stop on the finish line. The drivers who bet that it's possible then have to prove it to win. If they can't prove it, the drivers who bet against it win.
## The parcours
The rules for the parcours are as follows:
* A parcours consists of uphills, downhills and flat bits. In the examples, it's modelled as a sequence of `/`, `\` and `_` respectively.
* The bike starts with a speed of 0 m/s (i.e. before the first character of the sequence).
* The down-/uphills accelerate/decelerate the bike by 1 m/s.
* On the flat bits the driver must either speed up or slow down manually, again, by 1 m/s. They mustn't do nothing.
* If the bike has a speed of 0 m/s at the finish line (i.e. after the last character of the sequence), the parcours was driven correctly.
* The finish line must be reached.
* The speed must remain >= 0 at all times. If it is/becomes 0 at any point, the next piece of the parcours must accelerate the bike, either through a downhill `\` or through a flat bit `_` where the driver accelerates.
## The task
Given such a parcours, take it as the input for a first program and output whether it's possible or not to drive the parcours correctly according to the rules above. If yes, take the sequence as an input for a second program and output a sequence of instructions for the driver on what to do on the flat bits. In the examples, `+` and `-` are used to signalize acceleration and deceleration respectively.
## The rules
* This is [code-golf](/questions/tagged/code-golf "show questions tagged 'code-golf'"). The shortest answer wins.
* Submit one or two program/s that validate the parcours (validator) and generate the instructions for the driver if valid (generator). If two programs are submitted, they are scored seperately and independently from the one program submissions.
* The I/O format may be freely chosen. All characters may be substituted freely.
* The generator program only needs to work on parcours that can be driven correctly.
* The input length is not bounded.
## The examples

**Explanation:**
First following transformation is applied on the input: `\___/ -> ___`. This is done repeatedly, till the whole terrain is of following shape: `_/_/___\_\_` - rising from start and then falling till end.
Then following substrings are removed: `_/` and `\_`. Now the terrain is of flat shape `____` and it is just checked if the number of `_` is even.

Note: in both functions 4 bytes could be saved by replacing the boolean ands and or with bitwise ones, but it would be extremely slow.
In the generator, the ands before `(*x=*x-95?32:43)` and before `(*x=*x-95?32:45)` must be boolean in any case (otherwise it does not output the correct instructions).

Combines the Validator and Generator programs into a single program to save bytes.
Input as a list of characters.
Outputs an empty string as falsey, or `1` as truthy. In addition, outputs all possible generator outputs as a list of lists of `-1`/`1` for deceleration/acceleration respectively.

(The larger test cases are omitted; the more `_` are in the input, the slower the program becomes because of the `ã`.)
**Explanation:**
```
®1‚ # Push pair [-1,1]
„_\ # Push string "_\"
I # Push the input character-list
k # Get the 0-based index of each character in "_\",
# or -1 if it isn't present (in case of "/")
© # Store this list in variable `®` (without popping)
0¢ # Count the amount of 0s
ã # Get the cartesian product of the [-1,1] with this count
# (resulting in all possible count-sized list of -1s/1s)
ʒ # Filter this list by:
# (implicitly push the current list of -1s/1s
0 # Push a 0
® # Push list `®`
r # Reverse the order of these three
.; # Replace every 0 in list `®` with the -1s/1s of the current list in order
ηO¤Ā(ªdP # Check two things:
# 1. The sum results in exactly 0
# 2. No prefix is negative (so we never have any negative m/s speeds)
η # Get the prefixes of this list
O # Sum each inner prefix-list
¤ # Push the last sum (without popping), which is the sum of the full list
Ā # Check if it's NOT 0 (0 if 0; 1 otherwise)
( # Negate it (0 if 0; -1 otherwise)
ª # Append it to the list
d # Check for each inner integer if it's non-negative (>= 0)
P # Check if this is truthy for all of them
} # Close the filter
# (we now have a list of all possible paths if truthy; or [] if falsey)
Z # Push the flattened maximum (without popping): 1/-1 for truthy; "" for falsey
Ä # Get its absolute value: 1 for truthy; "" for falsey
= # Output it with trailing newline (without popping)
i # And if it was 1:
, # Also output the list itself on another line

If the parcour is valid, it just outputs the instructions; otherwise, it prints one or more bytes of value `0x01`, followed by some instructions (which are of course meaningless).

Note: it works only if the difference in height is always less or equal to `255`, counting from the start.

Note: for both programs, the input must be zero terminated.
Both programs works only if the total number of `+` and `-` of the output is less than `128`.

Following the standard calling convention for Unix-like systems (from the System V AMD64 ABI), this takes in RSI the address of the input, as a null-terminated byte string; takes in RDI an address at which to place a string, which will be the instructions for the driver if it's possible; and returns in EAX −1 if possible and 0 if impossible.
In assembly:
```
f:
xor edx, edx
```
Set EDX to 0. EDX will keep track of the minimum possible speed at each point.
```
push 1; pop rcx
```
Set ECX to 1. ECX will keep track of the maximum possible speed plus 1 at each point.
```
repeat:
lodsb
mov ah, al
```
Load a character from the string into AL, advancing the pointer, and then move it into AH.
```
mov al, '+'
```
Set AL to the ASCII code of '+'.
```
sahf
```
Set flags based on the character in AH. Here are the possibilities, with the important bits bolded:
```
S**Z** A **P** **C**
NUL 0**0**100**0**0**0**
\ 0**1**011**1**0**0**
_ 0**1**011**1**1**1**
/ 0**0**101**1**1**1**
```
```
jnp done
```
Jump if PF=0, true here only for the null terminator.
```
jnc must_accel
```
Jump if CF=0, true here only for `\`.
```
dec edx
jns second_part
```
(For `_` and `/`) Subtract 1 from EDX (the minimum speed). Jump if the result is nonnegative, in which case we are done with this part. Otherwise...
```
stosb
```
Write `+` to the output string, advancing the pointer.
```
inc edx
```
Add 1 to EDX. The next instruction adds 1 more, for a net +1.
```
must_accel:
inc edx
```
(For `\`) Add 1 to EDX.
```
second_part:
sahf
```
Set flags based on the character in AH again (as the `inc` or `dec` has overwritten them).
```
jnz must_decel
```
Jump if ZF=0, true here only for `/`.
```
add ecx, 2
```
(For `_` and `\`) Add 2 to ECX (the maximum speed plus 1); the next instruction will subtract 1, for a net +1.
```
must_decel:
loop repeat
```
(`/` jumps here) Subtract 1 from ECX and jump back if the result is nonzero (if the maximum speed did not drop to −1).
```
done:
```
If the parcours is possible, the minimum speed is 0, and the maximum speed is 2 times the number of flat pieces that should be decelerated on (because the maximum speed is obtained by accelerating on all of them, and changing one acceleration to a deceleration reduces the final speed by 2).
If it's not possible, either the end of the string has been reached with a nonzero minimum speed, or the loop ended prematurely with the maximum speed becoming −1 from a `/`, in which case the minimum speed will have changed from 0 to 1 on that `/`, and thus will also be nonzero.
```
shr ecx, 1
```
Shift ECX (the maximum speed plus 1) right by 1 bit. If the parcours is possible, this produces the number of flat pieces that should be decelerated on.
```
mov al, '-'
rep stosb
```
Put the character code of `-` in AL and write it to the output string ECX times, advancing the pointer and counting down ECX.
```
mov [rdi], cl
```
Add the low byte of ECX, which is now 0, to the output string.
```
sbb edx, ecx
```
Subtract ECX+CF from EDX. ECX is still 0. CF is the bit shifted out of ECX previously.
If the parcours is possible, CF will be 1 and EDX 0, so the result will wrap around to all 1s, and CF will be 1 afterwards.
If it's not possible, EDX will be nonzero and CF may be 0 or 1, but either way the result will not wrap around, so CF will be 0 afterwards.
```
sbb eax, eax
```
Subtract EAX+CF from EAX, making it −CF: −1 if possible and 0 if impossible.
```
ret
```
Return.

Outputs nothing if there are no flat bits or the input is invalid. Explanation:
```
+`
```
Repeat until all the instructions have been generated.
```
^(((?<-3>-|/)|(\+|\\))*)
```
Start by matching either `-` or `/` (removing from capture group `3` captured in a previous iteration), or either `+` or `\` (capturing into capture group `3`), repeating as much as possible, into capture group `1`.
```
((?<8-3>)|((?<3>)))
```
Either remove from capture group `3` and capture into group `8` or make another capture into capture group `3` and also capture group `5`. Then match the flat bit that we're going to create an instruction for, depending on which option was taken.
```
_(((?<-3>_|/)|(?<3>_|\\))*)
```
Match `_` or `/` (still removing from capture group 3) or `_` or `\` (still capturing into capture group 3) as much as possible into capture group `6`.
```
$(?(3)^)
```
The match needs to reach the end of the string and all of the captures in group 3 must eventually have been removed.
```
$1$#5$*+$#8$*-$6
```
Replace the flat bit with the desired instruction, leaving the prefix and suffix unchanged.

Remove anything that isn't an instruction.

[Robbers thread](https://codegolf.stackexchange.com/questions/242618/slice-the-source-code-robbers)
# Cops
## Understanding slicing
Remember, slices are zero-indexed. Take this slice: [2:]. If the string is "abcde", the result is "cde" because the slice basically means "get all elements with an index greater than 2." Let's try [1:3]. If there is an end slice, the end slice is not included. (excluded) Therefore, the result is "bc". What about [::2]? [::2] means "take every second element", so the result is "ace".
*Note: This is not a list of all the slicing features. For more info, see [here](https://stackoverflow.com/questions/509211/understanding-slice-notation).*
Cops, your job is to write to a program, that when sliced, will input a string and reverse it. The slice could be something like `[::-1][2::6]` which means "reverse the code, then get each sixth char starting from index 2."
The unsliced program must be valid code, and it does not need to do anything. It may not take any input. A valid program is a program that does not have anything in STDERR.
You must specify the number of slices. Both the unsliced and the sliced programs must be non-empty. You must include a slice.
## Scoring
Your score is the following:
$$
(sum of start slices\*2 + sum of end slices\*2 + sum of step slices\*3) \* code size in bytes before slice
$$
All fragments not included default to zero. Negative slices are made positive (-1 => 1, -2 => 2, ...)
Lowest score wins.
The tiebreaker is code size. Cracked answers are ineligible for scoring or winning.

Uhh, have fun I guess. Still not super difficult. (one slice is enough, just like for every other answer). This code contains non-ascii unicode characters. Those should be treated as one unit (not be broken up). If you use pythons slicing, and the source code is not a bytestring, you should be fine.

Maybe if I add enough deltarune references Lyxal will get distracted...
The solution was simply `Ṗt` - of all permutations, get the last. `[72:18:-1]` I think. Idk what the score is.

# [Symbolic Python](https://github.com/FTcode/Symbolic-Python), 10001 bytes
One slice, score is probably horrible, but maybe a bit more difficult to brute-force. The input is taken as a quoted command-line argument (like [this](https://tio.run/##K67MTcrPyUzWLagsycjP@w8CSiWpxSVKAA)).

Part of [**Advent of Code Golf 2021**](https://codegolf.meta.stackexchange.com/q/24068/78410) event. See the linked meta post for details.
Related to [AoC2020 Day 20](https://adventofcode.com/2020/day/20), Part 1. (This day is a dreaded one for many of you, I know :P)
*[Obligatory final "but you're not Bubbler"](https://chat.stackexchange.com/transcript/message/59962414#59962414) explanation*.
---
As the train carries you to the destination, you've got some spare time. You open the travel booklet for the vacation spot, and its map is divided into nine pieces... in random order and orientation. Apparently you got a brain teaser version of the booklet or something.
The map pieces are represented as a square grid of zeros and ones, and they are rotated and/or flipped in a random orientation. The four edges of each map piece are the clues: if two pieces have a common edge pattern (one of the four sides), two pieces are stitched together on that edge.
If two pieces look like this:
```
Piece 1:
#..##
##...
#.#.#
.#.##
....#
Piece 2:
#.###
.....
.#...
##..#
.##..
```
The right edge of Piece 1 and the top edge of Piece 2 match; you can flip Piece 2 with respect to its main diagonal, and then join the two horizontally.
You can't decide the orientation of the whole map yet, but at least you can assemble the 3x3 map and tell which piece goes to the center. This is the objective of this challenge.
The edge patterns are all distinct; for any given pattern that appears in the input, there are either exactly two pieces (for interior edges) or one (for outer edges) with that pattern. Also, every interior edge pattern is asymmetric, so that you can uniquely join the edges together (modulo orientation as a whole).
**Input:** A list of nine square grids of zeros and ones, representing the nine map pieces; you can choose any other two distinct values (numbers, chars, or strings) for zeros and ones.
**Output:** The square grid that corresponds to the center piece (any orientation is fine), or its index (0- or 1-based) in the input.
Standard [code-golf](/questions/tagged/code-golf "show questions tagged 'code-golf'") rules apply. The shortest code in bytes wins.

| 8 | `[0,0,0,0,1,0]` |
Given 6 integers, each of which is between \$0\$ and \$8\$ inclusive, we can use these rows to build a 6x6 square matrix. For example, consider an input of `[1,4,6,6,0,0]`. We'll start with `1` being the bottom row and the `0`s being the top 2, giving:
```
[0,0,0,0,0,0]
[0,0,0,0,0,0]
[1,0,0,1,0,1]
[1,0,0,1,0,1]
[1,1,0,1,1,1]
[1,1,1,1,1,1]
```
For each column in this matrix, we can see that every non-zero element has a "support" down to the base, i.e. no `1` has a `0` below it. However, this isn't the case for `[2,3,4,5,0,0]`:
```
[0,0,0,0,0,0]
[0,0,0,0,0,0]
[0,1,1,0,1,0]
[1,1,0,1,1,1]
[1,1,1,1,1,1]
[1,1,1,1,1,1]
```
As the third column from the left has a `0` below the top `1`, meaning that it is "unsupported".
Given 6 integers between `0` and `8` inclusive, in any reasonable format, you should output a truthy value if, in the matrix represented by these numbers, all non-zero values are supported; and a falsey value if not.
This is [code-golf](/questions/tagged/code-golf "show questions tagged 'code-golf'"), so the shortest code in bytes wins.
Test cases:
```
[1,4,6,6,0,0] => valid
[2,1,2,4,7,7] => valid
[5,8,8,0,0,0] => valid
[2,0,2,0,0,0] => invalid
[2,3,4,5,0,0] => invalid
```

## How it works
```
ị“???7ȷ%Ñ£¡‘&\Ƒ - Main link. Takes a list of integers on the left
“???7ȷ%Ñ£¡‘ - Integer list; [63, 63, 63, 55, 26, 37, 16, 2, 0]
ị - For each i in the input, get the ith element of the list
Ƒ - Is the list of numbers unchanged when doing:
\ - Scan by:
& - Bitwise AND
```
We can avoid having to convert to binary by using bitwise AND instead of logical AND. By scanning a column (treating the numbers as binary) with a zero bit "hole" with AND, it'll overwrite it as a `1`, thus changing the number represented. If there are no holes, none of the numbers will change.

### How?
When trying to actually process the patterns, my best attempt was [**49 bytes**](https://tio.run/##hc2xDoIwFIXhxNHJ2YlF0yZXKEXApTTxNZCEBlqDwbahyuir165q1Pzrl3MuYhaumwZ722nTS6@YF6wSsTNXiTSrHnaLLDvelZITak@Ec16uN6tFi2vdYLCsyLDvjHZmlPFozkihOoU9FCECpME4SpJoFuPQL98YhRRooCWUv1gOhxD5v0aAvrBBf4FZOM0/oX8C). It turns out that looking for invalid consecutive indices is shorter (at least in JS).
For each index \$0\le p\le 8\$, [we generate](https://tio.run/##nY9BDoIwEEX3PcV3Y0qsBHcmiDfgBE0XDYJikLYU2RjOjgUEhaXJNNP@eZ2Zf5eNtEmV63pfqkvadUVaI0YETgAeMCxCsF49MCziXzVYqfN7vHynBbO0Yteb/S47dCAiJCRTFe1taWcrCF06RTi6vNt5eLlvfU32lh0MTLQZafOhzUQDeUZjroVv1SOltGHIPURnbBpsEXMjeC68iQWkr5/2Ro0XDkJLxpOo0qoi9Qt1pZpBunLbdW8) the list of indices \$n\$ that cannot appear right after \$p\$:
```
0 → [ 1, 2, 3, 4, 5, 6, 7, 8 ]
1 → []
2 → []
3 → []
4 → [ 1, 2, 3, 5 ]
5 → [ 1, 2, 3, 4, 6 ]
6 → [ 1, 2, 3, 4, 5, 7, 8 ]
7 → [ 1, 2, 3, 4, 5, 6, 8 ]
8 → [ 1, 2, 3, 4, 5, 6, 7 ]
```
It follows that \$n\$ is invalid iff all the following conditions are met:
* \$p\$ is defined
* \$n\neq p\$
* \$n\neq 0\$
* \$n<A\_p\$, with \$A=[9,0,0,0,6,7,9,9,9]\$

First time goling in Python a while. We store a binary matrix as a string.
This represents
\$
M= \left[\begin{matrix}
1 & 1 & 1 & 1 & 1 & 1 & 1 & 1 & 1 \\
0 & 1 & 1 & 1 & 0 & 0 & 0 & 0 & 0 \\
0 & 1 & 1 & 1 & 0 & 0 & 0 & 0 & 0 \\
0 & 1 & 1 & 1 & 0 & 0 & 0 & 0 & 0 \\
0 & 1 & 1 & 1 & 1 & 0 & 0 & 0 & 0 \\
0 & 1 & 1 & 1 & 0 & 1 & 0 & 0 & 0 \\
0 & 1 & 1 & 1 & 1 & 0 & 1 & 0 & 0 \\
0 & 1 & 1 & 1 & 1 & 1 & 0 & 1 & 0 \\
0 & 1 & 1 & 1 & 1 & 1 & 0 & 0 & 1 \\
\end{matrix}\right]
\$
Where \$M\_{i,j}\$ is whether \$i\$ can be placed on top of \$j\$. Basically its the adjacency matrix of the underlying lattice. Then with this matrix we check all the pairs of indices and see if anything is adjacent to something it can't be.

2 % Push this number
O % Push 0
v % Concatenate everything into a column vector. (*)
i % Input: numeric vector
) % Index into (*). Indexing is 1-based and modular, so index 0
% corresponds to the last entry
B % Convert to binary. Gives a matrix, each original number corresponding
% to a row. The number of columns is determined by the longest binary
% expansion

Translate each digit to a custom bitmask, given by the bottom 4 bits of the ASCII codes of each character (the upper bits are the same for each character so they don't affect the final result).
```
⬤θ∨¬κ⁼ι｜ι§θ⊖κ
```
Check that the bitmasks represent a supported matrix.
The custom bitmasks are as follows:
```
0 1111
1 0000

3 0000
4 0001
5 0010
6 1101
7 0111
8 1011
```
Calculation of the adjacency matrix will result in the same matrix as the original bitmasks. Note that these masks are inverted so the code uses a bitwise OR check to compensate.

## Background
Consider the shape \$T(n)\$ consisting of a triangular array of \$\frac{n(n+1)}{2}\$ unit regular hexagons:
[](https://i.stack.imgur.com/oUzDh.jpg)
John Conway proved that \$n = 12k + 0,2,9,11\$ if and only if \$T(n)\$ can be tiled (i.e. exactly covered without overlapping) with \$T(2)\$. At the same time, he also proved that no coloring argument could prove the fact. (Yes, this is yet another Conway challenge.)
## Challenge
Let's define \$a\_n\$ as the number of distinct tilings of \$T(n)\$ by \$T(2)\$. Compute as many terms of \$a\_n\$ as possible in 10 minutes.
Reflection and/or rotation of a tiling is considered distinct from itself, unless the two are identical.
The program that prints the largest number of terms wins. In case of tie, the one that prints the last term in shorter time wins.
I have a Windows 10 machine with `Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz` and 32GB RAM, with Ubuntu 18.04 installed in WSL. Please include the instructions to run your code and where it works (Windows or Linux).
## Output format (with test cases)
The submission should print the results infinitely for each \$n\$ starting from 0. Each line should include the values of \$n\$ and \$a\_n\$. Here is first 21 lines of the expected output:

A recursive search using bit masks and a cache to keep track of patterns whose result is already known.
It doesn't make much sense to try go further in Node. Using a binary matrix is significantly slower and BigInts are even slower. It should rather be ported to a language natively supporting 64-bit integers.
```

# [Rust](https://www.rust-lang.org/), \$n \le 44\$ in 42 seconds
Build with `rustc -O`. Uses about 800 MiB of memory for \$n = 38\$, and \$39 \le n \le 44\$ are trivial. \$n = 45\$ will almost definitely run out of both time and memory on any reasonable system.
It works by dynamic programming where the states are the presence or absence of hexagons at \$(k - 1, 1), \dotsc, (k - 1, i), (k, i + 1), \dotsc, (k, k)\$; we advance \$i\$ to \$i + 1\$ by considering the addition of tribone \$(k, i + 1), (k - 1, i), (k - 1, i + 1)\$ or \$(k, i + 1), (k - 1, i + 1), (k, i + 2)\$.

[Question]
[
Here are the annual returns for a hypothetical S&P 500 stock index fund for each calendar year from 1928 to 2017, expressed as a multiplier. So in 1928 you might say "the index went up by 37.88%" which I've represented here by 1.3788.
```
1.3788, 0.8809, 0.7152, 0.5293, 0.8485, 1.4659, 0.9406, 1.4137, 1.2792, 0.6141, 1.2521, 0.9455, 0.8471, 0.8214, 1.1243, 1.1945, 1.138, 1.3072, 0.8813, 1, 0.9935, 1.1026, 1.2178, 1.1646, 1.1178, 0.9338, 1.4502, 1.264, 1.0262, 0.8569, 1.3806, 1.0848, 0.9703, 1.2313, 0.8819, 1.1889, 1.1297, 1.0906, 0.8691, 1.2009, 1.0766, 0.8864, 1.001, 1.1079, 1.1563, 0.8263, 0.7028, 1.3155, 1.1915, 0.885, 1.0106, 1.1231, 1.2577, 0.9027, 1.1476, 1.1727, 1.014, 1.2633, 1.1462, 1.0203, 1.124, 1.2725, 0.9344, 1.2631, 1.0446, 1.0706, 0.9846, 1.3411, 1.2026, 1.3101, 1.2667, 1.1953, 0.8986, 0.8696, 0.7663, 1.2638, 1.0899, 1.03, 1.1362, 1.0353, 0.6151, 1.2345, 1.1278, 1, 1.1341, 1.296, 1.1139, 0.9927, 1.0954, 1.1942

## Challenge
Given as inputs:
* the array of annual returns (but see Rule 2. below)
* an array \$X\$ of \$1\le K \le 90\$ positive numbers (the amounts to invest in each year of the investment period)
write a program or function that outputs what would have been the "best" \$K\$ consecutive year period to have invested the amounts in \$X\$, where:
* each amount is invested at the beginning of a year.
* anything left after each year is reinvested at the beginning of each subsequent year.
* "best" means the largest amount at the end of the \$K\$ year period.
## Rules
1. This is [code-golf](/questions/tagged/code-golf "show questions tagged 'code-golf'"), so the fewest bytes in each language wins. Standard rules apply. Explanations encouraged.
2. If you don't like the way I've represented the array of annual returns, you can change them to any other array of 90 numbers that you prefer.
3. You can output the best \$K\$ year period in any consistent manner (e.g. 0-indexed or 1-indexed, the first and/or the last year to have invested, etc.) but you need to say what your output represents if it isn't obvious.
4. In case of a tie, output any or all correct answers.
## Example calculation
Suppose \$X = [ 10000, 20000, 30000 ]\$.
If you had invested these amounts in 1928, 1929, and 1930 (the 1-indices 1, 2, and 3) you would have ended up with 42743.10. Sad.
But if you had invested those amounts in 2014, 2015, and 2016 (the 1-indices 87, 88, and 89) you would have ended up with 66722.66. A bit better.
It turns out the *best* three year period to have invested these amounts would have been 1995, 1996, and 1997 (1-indices 68, 69, and 70), resulting in 91942.91. Nice.
## Test cases
1-indexed, first year of optimal period
```
[ 1, 2, 3 ] -> 68
[ 1 ] -> 6
* any array of length 90 * -> 1
[ 1, 1 ] -> 27
[ 1, 2 ] -> 8
[ 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1 ] -> 62
[ 1, 2, 3, 4, 5, 4, 3, 2, 1 ] -> 64
* 1 repeated 20 times * -> 53

Takes the list of returns as [this array](https://pastebin.com/L3ia9T0j), which is an array of 90 strings where each string contains a base-10 integer padded to 1929 digits; I believe this technically meets the requirements. The "Try it" link only has the first element of the "returns" list because the full thing broke the permalink generator, but that's the only one that gets used. You can paste in the whole thing from the pastebin if you want.
Explanation:
As mentioned, only the first element of the "returns" array is actually used; every other element is 0 in the pastebin and ignored by the program. The first element is generated by [this](https://ethproductions.github.io/japt/?v=1.4.6&code=cSBtYyD5JzAgcQ==&input=IlU9WzEuMzc4OCwwLjg4MDksMC43MTUyLDAuNTI5MywwLjg0ODUsMS40NjU5LDAuOTQwNiwxLjQxMzcsMS4yNzkyLDAuNjE0MSwxLjI1MjEsMC45NDU1LDAuODQ3MSwwLjgyMTQsMS4xMjQzLDEuMTk0NSwxLjEzOCwxLjMwNzIsMC44ODEzLDEsMC45OTM1LDEuMTAyNiwxLjIxNzgsMS4xNjQ2LDEuMTE3OCwwLjkzMzgsMS40NTAyLDEuMjY0LDEuMDI2MiwwLjg1NjksMS4zODA2LDEuMDg0OCwwLjk3MDMsMS4yMzEzLDAuODgxOSwxLjE4ODksMS4xMjk3LDEuMDkwNiwwLjg2OTEsMS4yMDA5LDEuMDc2NiwwLjg4NjQsMS4wMDEsMS4xMDc5LDEuMTU2MywwLjgyNjMsMC43MDI4LDEuMzE1NSwxLjE5MTUsMC44ODUsMS4wMTA2LDEuMTIzMSwxLjI1NzcsMC45MDI3LDEuMTQ3NiwxLjE3MjcsMS4wMTQsMS4yNjMzLDEuMTQ2MiwxLjAyMDMsMS4xMjQsMS4yNzI1LDAuOTM0NCwxLjI2MzEsMS4wNDQ2LDEuMDcwNiwwLjk4NDYsMS4zNDExLDEuMjAyNiwxLjMxMDEsMS4yNjY3LDEuMTk1MywwLjg5ODYsMC44Njk2LDAuNzY2MywxLjI2MzgsMS4wODk5LDEuMDMsMS4xMzYyLDEuMDM1MywwLjYxNTEsMS4yMzQ1LDEuMTI3OCwxLDEuMTM0MSwxLjI5NiwxLjExMzksMC45OTI3LDEuMDk1NCwxLjE5NDJdO1U941ZsKW3tViCucsgrWcwgKllnfTB9O2JVcnci), which takes the string representation of a Japt program, turns each character into a 3 digit number, and joins those numbers into a new string of just digits.

## ungolfed
```
1 + [: (i. >./) [: ({:@[ * {.@[ + */@])/"2 [ |.@,."1 #@[ ]\ ]
```
## how
Take input list (eg, `123`) on left, data on right.
`#@[ ]\ ]` Chop up the data into infixes whose length matches the input:
```
1.3788 0.8809 0.7152
0.8809 0.7152 0.5293
0.7152 0.5293 0.8485
```
`[ ,."1` now zip each of those groups of 3 with the input list
```
1 2 3
1.3788 0.8809 0.7152
1 2 3
0.8809 0.7152 0.5293
1 2 3
0.7152 0.5293 0.8485
```
`|.@` and reverse them:
```
3 2 1
0.7152 0.8809 1.3788
```
`(verb to insert)/"2` Between the items of each zipped group of 3, insert the
verb in parentheses.
```
3 2 1
VERB VERB
0.7152 0.8809 1.3788
```
`({:@[ * {.@[ + */@])` is the inserted verb, which will reduce each item of the list of zipped groups of threes down to one number, which is the amount
earned over that group of years:
```
2. plus the first 1. */] = product of right args
(top) item on left
+-+ +--------+
|2| + | 1 |
+-+ | * |
| 1.3788 |
* +--------+
0.8809
3. Multiply that sum by the bottom
number on the left.
```
`(i. >./)` Take the list thus reduced and find the index of the max.
`1 + [:` And add one

The return factor on a deposit is the cumulative product of the return factors in the years until the end of the `K` year period. If we're allowed to take the input in reverse and output a year number as 2018-[end date], the **10 bytes** solution `×\⁹L¤Ƥ×S€M` works.

[Question]
[
I have a series of binary switches, which I can represent as a bit string. The last person who used my switches left them in some arbitrary state without cleaning up, and it bugs me. I always keep the switches in one of four possible "tidy" configurations:
* All `1`: e.g., `111111111`
* All `0`: e.g., `000000000`
* Alternating `1` and `0`: e.g., `10101010` or `01010101`
However, in addition to being fastidious about my switch arrangements, I'm also very lazy, and want to extend the smallest amount of effort possible to reset the switches to one of my preferred states.
# Challenge
Write a program or function that takes a sequence of ones and zeros of any length. It should output a result of the same length that shows the closest "tidy" configuration.
## Input and output
* You may represent your bit sequence using a string or any language-native ordered type, such as a list or array. If using a non-string structure, items within the sequence may be number or string representations of `1` and `0`.
+ Your strings may have leading and trailing characters like `"..."` or `[...]`
* Your input and output formats are not required to match. (For example, you may input a list and output a string.)
* Don't input or output base 10 (or other base) representations of the bit string. That's way too much effort to correspond back to switches -- I'm doing this because I'm lazy, remember?
* Output must be a sequence as specified above. Don't output an enumerated value saying which of the four configurations is the best (e.g., don't say, "solution is case #3"). Actually output a bit sequence in that configuration.
* Input may be of any length. Your code may not impose arbitrary limits on the size of the input.
+ If your language or interpreter imposes reasonable arbitrary limits on the size of an input or call stack (e.g, if you choose a recursive solution), then this is acceptable insofar as it is a shortcoming in your environment, not your code.
## Notes
* The distance between two strings is the [Hamming distance](https://en.wikipedia.org/wiki/Hamming_distance). You must find the "tidy" configuration of the same length at the input that has the fewest number of differences from the input.
* If multiple tidy configurations are equally best choices, you may output any best choice, or (at your option) multiple best choices, delimited in some way or as siblings in a data structure. The selection can be completely arbitrary and does not need to be consistent between executions.
* The input might already be a tidy state.
## Examples
```
Input: 1111110
Output: 1111111
Input: 001010000
Output: 000000000
Input: 0010100
Allowed output: 0000000
Allowed output: 1010101
[You may choose either allowed output, or both]
Input: 1111
Output: 1111
Input: 10
Output: 10
Input: 010101101
Output: 010101010
Input: 110
Allowed output: 111
Allowed output: 010

This code constructs the four "tidy" strings by elongating the bit representations of numbers 0 to 3 to the required size, and then selects the one that gives the minimum Hamming distance to our test string.
The distance is calculated by XORing the integer representations of strings, and in theory we should then count the number of set bits in the result. But in practice, string byte `sum` method works just as well, and is golfier. The only extra trick that is now necessary, is to pad one of the bit strings with an extra "1" in front: `0xb1...` to prevent dropping of leading zeroes in the result, as they are important for `sum`.

**Explanation:**
```
a->{ // Method with integer-array as both parameter and return-type
int l=a.length, // Length of the input-array
b[][]=new int[4][l],
// Integer matrix of 4 rows and `l` columns
i=4*l, // Index integer
y, // Temp integer
r=l, // Result smallest difference with the input-array
R[]=a; // Result-integer array
for(;i-->0;) // Loop over the cells:
b[y=i/l][i%l]= // Set `y` to the current cell's y-coordinate,
// and fill this cell in the matrix with:
y<2? // If this is the first or second row:
y // Fill this cell with this 0 or 1 from `y`
: // Else:
i%l+2/y&1; // Fill it with `(x+2//y)%2` instead
// (which is `x%2` for the third row
// and `(x+1)%2` for the fourth row)
for(var B:b){ // Loop over the rows of the matrix:
for(i=y=0; // Reset `y` to 0, and use it as sum
i<l;) // Inner loop over the cells of the matrix
y+=a[i]^B[i++]; // Add the xor of the values at the same positions
// of both the input array and current row to the sum
if(y<r){ // If the sum is smaller than the current smallest difference:
r=y; // Set the sum as new smallest difference
R=B;}} // Set the result-array `R` to the current row of the matrix
return R;} // Return the resulting array with the smallest difference
```
**Example: Input-array `[0,1,0,1,0,1,1,0,1]`**
The first nested loop creates the following matrix, where the rows are the same length as the input:
```
[[0,0,0,0,0,0,0,0,0],
[1,1,1,1,1,1,1,1,1],
[0,1,0,1,0,1,0,1,0],
[1,0,1,0,1,0,1,0,1]]
```
The second nested loops uses an XOR between each value at the same position in this row and the input-array, and sums that together:
```
[0^0 + 1^0 + 0^0 + 1^0 + 0^0 + 1^0 + 1^0 + 0^0 + 1^0 = 5,
0^1 + 1^1 + 0^1 + 1^1 + 0^1 + 1^1 + 1^1 + 0^1 + 1^1 = 4,
0^0 + 1^1 + 0^0 + 1^1 + 0^0 + 1^1 + 1^0 + 0^1 + 1^0 = 3,
0^1 + 1^0 + 0^1 + 1^0 + 0^1 + 1^0 + 1^1 + 0^0 + 1^1 = 6]
```
And then it returns the row with the lowest XOR-sum, which is `[0,1,0,1,0,1,0,1,0]` (`3`) in this case.

[Question]
[
Pig-latin is a made-up language that is translated into by moving the first letter of a word to the end and adding `ay` to the end. For example: `hello` translates into pig-latin as `ellohay`. Therefore, translating pig-latin back into English is dropping the `ay` at the end and moving the last letter to the start (like `oodbyegay` to `goodbye`). When writing it out, some people will put a `-` at the end before moving the first letter for clarity, so it reads (for example) `ello-hay` instead of `ellohay` for `hello`. We will use this hyphenated version for this challenge.
# Objective
Undo a pig-latin string.
# Instructions
Write a program/function that takes one argument, a *single* word in the form of a string. If that word is in pig-latin, the program/function must output (i.e. `return` or print it) the non-pig-latin word. If it isn't pig-latin, output the word as-is.
Pig-latin for this challenge will be in the following format:
```
ello-hay
```
If the word ends in `-*ay`, it is pig-latin, where the `*` is a single wildcard character.
Non-letter characters should be treated as a normal letter. For multiple dashes, ignore all except the last.
# Examples
Using fictitious `unpig()` Python function for demo.
```
unpig("ello-hay") #=> hello
unpig("hello-world") #=> hello-world
unpig("hello") #=> hello
unpig("pple-aay") #=> apple
unpig("apple") #=> apple
unpig("ig-Stay") #=> ig-Stay (+1 to ETHproductions for noticing.)
unpig("ello----hay") #=> hello---
unpig("la$s-gay") #=> gla$s
unpig("ig-pay-yay") #=> yig-pay
```

[Question]

**Note:** I have accepted an answer, but I'm willing to accept a better answer if it comes.
Write a program that computes operations on sets. You may take input either from standard input or from command line arguments. Your program must be able to compute unions, intersections, relative complements, and cartesian products. Output should be the result of these operations.
You may not use built-in functions to do the work for you.
## Input Format
`<A>` and `<B>` represent sets. The format for sets can be anything that is convenient, as long as it *actually represents a set* (no taking advantage of this "looseness"). The elements of a set don't always have to be in the same order because sets aren't ordered. You define what kind of object these elements can be (integers, letters, ...).
* Union: `union <A> <B>`
* Intersection: `intersect <A> <B>`
* [Relative complement](http://en.wikipedia.org/wiki/Complement_(set_theory)#Relative_complement) (difference of sets): `complement <A> <B>`
* Cartesian product: `product <A> <B>` (format for ordered pairs can be anything convenient -- don't take advantage of this "looseness" either)
**For info on what these operations even are, see [the Wikipedia page on it](http://en.wikipedia.org/wiki/Set_(mathematics)#Basic_operations).**

Okay, now time to explain this gobbledygook. First, here's an explanation of how it chooses which one of the four blocks (union, intersect, complement, product) to execute.
I noticed something convenient about these commands. They each begin with a unique letter (`u`, `i`, `c`, `p`). Therefore, we only care about this first letter.
Now, to make the code even shorter, these can be converted into ASCII codes (117, 105, 99, 112). Here's an explanation of the main logic of the program:
```
( # grab the ASCII code of the first letter of the input string
\~ # evaluate the rest of the string. GS will ignore "nion", "tersect", etc.
@ # stack is now [A B CMD]
99-:x # subtract 99 for shorter code. Now 'uicp' maps to [18 6 0 13]
```
After this comes a huge chain of `if`s. With the set operation logic removed, it looks like this:
```
{6x={INTERSECT_CODE}{13x={PRODUCT_CODE}{UNION_CODE}if}if}{COMPLEMENT_CODE}if`
```
Converted to a more readable C-like format, it looks like this:
```
if (x) {
if (x == 6) {
INTERSECT_CODE
} else {
if (x == 13) {
PRODUCT_CODE
} else {
// x must be 18
UNION_CODE
}
}
} else {
// x is 0
COMPLEMENT_CODE
}
```
Now, it's just a matter of looking at the code for the set operations. Most of them are fairly straightforwards: `&` for intersect, `|` for union, and `-` for complement. However, GolfScript doesn't have a built-in product operator, so I had to build some Ruby code for that. Here's an explanation of that mess:
```
'"#{[' # stack: [1 2 3] [2 3 4] '"#{['
@','*+ # stack: [2 3 4] '"#{[1,2,3'
'].product ['+ # stack: [2 3 4] '"#{[1,2,3].product ['
\','*+ # stack: '"#{[1,2,3].product [2,3,4'
']}"'+ # stack: '"#{[1,2,3].product [2,3,4]}"'
~ # evaluate
```
Simply tack on a ``` to show array output correctly, and it's done!

# Bash+coreutils, 200 bytes
I'm not exactly sure what *"You may not use built-in functions to do the work for you"* means, but I am assuming it means no use of APIs **specifically** designed for handling sets. Some of the coreutils used here might be considered to come close, but I am asserting that these utilities operate on files and lines of files, and not specifically on sets:
```
f()(tr \ \\n<<<$1|sort -u)
c()(comm -2$1 <(echo "$a") <(echo "$b"))
a=`f "$2"`
b=`f "$3"`
case $1 in
u*)sort -u<<<"$a
$b";;i*)c 1;;c*)c 3;;p*)eval printf '%s\\n' {${a//$'\n'/,}},{${b//$'\n'/,}};;esac
```
The **union**, **intersect** and **complement** cases are relatively uninteresting calls to `sort` and `comm`.
The **product** case uses [bash brace expansion](https://www.gnu.org/software/bash/manual/html_node/Brace-Expansion.html). For example `echo {1,2,3},{a,b}` produces the output `1,a 1,b 2,a 2,b 3,a 3,b`. The catch here is that [brace expansion normally occurs before variable expansion](https://www.gnu.org/software/bash/manual/html_node/Shell-Expansions.html#Shell-Expansions), so the whole thing must be `eval`ed so the variables are effectively expanded first.
Example output:
```
$ ./sets.sh union "1 2 3 4 3 2 1" "2 4 6 4 6"

## Haskell, ~~123~~ 96 bytes
Saved the `import Control.Applicative` part since `liftA2` is now in `Prelude`.
Not sure whether this is considered cheating, but:
```
union=liftA2(||)
intersect=liftA2(&&)
complement f=liftA2(&&)f.(not.)
product f g (x,y)=f x&&g y
```
If allowed, `product` could be curried to save extra 1 byte.
The key idea is to implement sets as a predicate (`a -> Bool`) that returns `True` if the element is present. This can represent not only finite sets, but also infinite sets.
Being possibly infinite, the outputted set cannot be represented in a string, but it can be queried:
```
Prelude> union (\_->False) (\_->False) 0
False
Prelude> union (\_->False) (\_->True) 0
True
Prelude> union (\_->False) even 0
True
Prelude> union (\_->False) odd 0
False
Prelude> union even odd 0
True
Prelude> intersect (\_->False) (\_->True) 0
False
Prelude> intersect (\_->True) even 0
True
Prelude> intersect odd even 0
False
Prelude> complement (\_->True) even 0
False
Prelude> complement (\_->True) odd 0
True
Prelude> product even odd (0,0)
False
Prelude> product even odd (0,1)

```
## Explanation
We can check the first character (infer O) to check if it's union, intersect, complement, or product. However, if it doesn't extend it, we can parse the array of values provided (as this is a self-recursive function). Set operations are native to TypeScript's Type System, so implementing each one is trivial, with union and intersect being native TS operators (`|` and `&` accordingly), cartesian joins using a joined json object, and complement using the `Exclude` type.

Returns a `list` with four elements, the Union, the Intersection, the Difference, and the Cartesian Product, in that order.
Takes input as an R vector of integers.
The Union is the unique values in the concatenation of the two vectors, `U=unique(c(A,B))`.
The Intersection is the subset of the Union where `x in A & x in B`, so `U[U%in%A&U%in%B]`.
The Set Difference is those `a in A` where `a notin B`, so `A[!A%in%B]`
The Cartesian Product is returned as a matrix where each row is an ordered pair. It repeats `A` `|B|` times and the elements of `B` `|A|` times each, then binds them together as matrix columns, i.e.:
```
cbind( # bind as matrix columns
rep(A,sum(B|1)), # repeat A |B| times (concatenate |B| copies of A)
rep(B,e=sum(A|1))) # repeat each element of B |A| times

The answer to [this question](https://stackoverflow.com/q/12850950/174728) is much too long
Your challenge is to write a **partitioning function** in the smallest number of characters.
Input example
```
['a', 'b', 'c']
```
Output example
```
[(('a'),('b'),('c')),
(('a', 'b'), ('c')),
(('a', 'c'), ('b')),
(('b', 'c'), ('a')),
(('a', 'b', 'c'))]
```
The input can be a list/array/set/string etc. whatever is easiest for your function to process
You can also choose the output format to suit yourself as long as the structure is clear.
Your function should work for at least 6 items in the input

### GolfScript, 51 characters
```
{[[]]\{[.;]`{1$[1$]+@@`1$`{[2$]-@@[+]+}++/}+%}/}:P;
```
The script defines a variable `P` which takes an array from top of the stack and pushes back a list of all partitions, e.g.
```
[1 2] P # => [[[1] [2]] [[1 2]]]
["a" "b" "c"] P # => [[["a"] ["b"] ["c"]] [["b"] ["a" "c"]] [["a"] ["b" "c"]] [["a" "b"] ["c"]] [["a" "b" "c"]]]
```
It does also work on larger lists:
```
6, P ,p # prints 203, i.e. Bell number B6
8, P ,p # 4140
```

Basically an optimization of [Keith Randall's solution](https://codegolf.stackexchange.com/a/919/20260) of zeroing out numbers that are multiples of squares. The main improvement is directly zeroing out the sublist `A[i*i::i*i]`, which requires awkwardly calculating its length or else Python refuses to do the slice assignment.
Lots of `~-` are used for `-1`. The `~-sum(A)` corrects for `0` being falsely counted as a squarefree number.

# Java - 278 Characters
A golfed version of the [Java answer](https://codegolf.stackexchange.com/a/897/32114) already demonstrated here without changing the spirit of the answer, because the original poster's idea golfed could have saved 50%, which is huge compared to most other languages!
```
class T {public static void main(String[] a) {int n,i,j;double k;n=Integer.parseInt(a[0]);int l[]=new int[n];for(i=0;i<n;)l[i]=1+i++;for (i=1;i<n;i++) {k=Math.sqrt(l[i]);if(k==Math.floor(k))for (j=i;j<n;j+=i+1)l[j]=-1;}j=0;for(i=0;i<n;)if(l[i++]!=-1)j++;System.out.println(j);}}
```
Specifically, a few Java golfing tricks were used to optimize this:
* Removed long variable names
* Removed the use of a Reader in favor of using an argument (saves a huge amount of characters, including import, Exception handling, and casting the reader in general)
* Removed extra brackets and parentheses using single-line actions for ifs and fors where applicable
* Declare ints beforehand together to reduce calls to int
* Declare a double and optimize square calculation
* Extracted ++ where possible
This shows that the original ungolfed solution of 565 characters can be brought down to a very respectable <300 character answer even with a more structured language like Java.
### Ungolfed
```
class T {
public static void main(String[] a) {

k = Math.sqrt(l[i]);
if (k == Math.floor(k))
for (j = i; j < n; j += i + 1)
l[j] = -1;

This factors every number up to N, removes the last line (as we're only counting results strictly less than N), and removes any line with a repeated word. Finally, we count the remaining lines.
The regular expression `\( .*\)\1\b` looks over-generous, but it takes advantage of what we know about the output of `factor` - the factors will be in ascending order, with exactly one space between each.

[Question]
[
I'm trying to shorten a bash solution to a Code Golf challenge, which requires an output of `true` or `false`. I've managed to condense the key piece of the code down to a substring check, to determine if the provided argument, `$1`, is a substring of a particular hard-coded fixed string, of the form:
```
[[ FIXEDSTRING = *$1* ]]&&echo true||echo false
# And a minor improvement to shave a character on the test:
[[ FIXEDSTRING =~ $1 ]]&&echo true||echo false
```
**My question is, is there some clever way to shorten this, either in general, or for the specific case of converting success to `true` and failure to `false`?**
In a language like Python, I'd use:
```
# Shortest solution without imports I know of
str(sys.argv[1]in"FIXEDSTRING").lower() # Also feels a little long, kinda
# curious if there is a better way
# Shorter when json is already imported for some other purpose, saves a character (more if
# json aliased or dumps denamespaced via from json import*):
json.dumps(sys.argv[1]in"FIXEDSTRING")
```
for the specific case of "success is `true`, failure is `false`", and one of:
```
# When string lengths close enough for stepped slicing to work, only 3 characters longer
# than the true/false specific solution
"ftarlusee"[sys.argv[1]in"FIXEDSTRING"::2]
# When string lengths aren't compatible for stepped slicing,
("false","true")[sys.argv[1]in"FIXEDSTRING"]
```
when I need to select between arbitrary strings, not just `true`/`false`.
But AFAICT:
1. `bash` has no concept of converting from success/failure to a specific string (without relying on `if`/`then`/`fi`,`case`/`esac` or `&&`/`||` and manually running `echo` with a literal string for each string option)
2. `bash` arrays can't be used "anonymously", and the array indexing and slicing syntax is so verbose you can't save any characters this way (e.g. `a=(true false);[[ FIXEDSTRING = *$1* ]];echo ${a[$?]}` is six characters longer than my current approach; useful if I needed to convert exit status to true/false in multiple places, but not for a one-off use)
3. Stepped slicing of a string isn't a thing.
[Answer]
Here's a slightly shorter method in pure Bash. It doesn't beat the `expr` based method, but it doesn't use any utils.
```
false
[[ FIXEDSTRING =~ $1 ]]&&true
echo $_
```
[Answer]
This one is the **same size** as the `expr` method while still being **pure Bash**. It takes advantage of `$_` and the fact that `true`/`false` are builtins that simply returns the status you would expect.
```
FIXEDSTRING
${_/*$1*}true||false
echo $_
```
##### Explanation:
* "FIXEDSTRING" gets stored into `$_` by attempting to execute it with no args.
* If $1 is a substring of "FIXEDSTRING", then it will be removed in the pattern replacement and allows Bash to execute the `true` builtin.
* Otherwise, the pattern replacement will result in no change to "FIXEDSTRING" if it's not a substring, thus executing `FIXEDSTRINGtrue`, which is not a valid command and fails through to executing `false`. Thus putting either "true" or "false" into `$_` based on the pattern replacement result.
* `$_` is then echoed out.
[Answer]
I found one way to improve on this using [the `expr` command](https://www.man7.org/linux/man-pages/man1/expr.1.html); not `bash` itself, but at least a GNU coreutil so it exists pretty universally (and more importantly, on the Code Golf test bed):
```
expr true \& FIXEDSTRING : .*$1 \| false
```
`FIXEDSTRING : .*$1` is a regex pattern match; it's implicitly anchored with a leading `^`, thus the need for the `.*` in front of `$1` (probably would need to be `.\*$1` if there was a possibility of a file with a name matching the pattern). `true \&` will evaluate to the string `true` if the pattern match succeeds, and `0` otherwise, which, when paired with `\| false`, will replace all cases where it evaluated to `0` with the string `false`. Shaves off seven characters from my original approach (and six characters relative to the slightly shorter version I updated the question with, using `=~` to avoid a pair of `*`s).
If anyone can come close to that with pure `bash`, or beat it using near-universally available tools like `expr`, let me know; I'll happily accept such an answer.
[Answer]
Here's an option that abuses the filesystem for 41 bytes:
```
echo true>FIXEDSTRING
dd<*$1*||echo false
```

This requires that your fixed string is not empty, `.`, `..`, nor contains `/`.
[Answer]
Found a `sed`-based solution that beats `expr` significantly. Obviously not a `bash` built-in, but it's using solely portable `sed` features AFAICT so it should be near universally available:
```
sed "/$1/ctrue
cfalse"<<<FIXEDSTRING
```
`/$1/ctrue` selects "lines" (there's only one line) which match the regex from `$1`, and `ctrue` short-circuits for that line, emitting `true` and discarding the line. If it wasn't short-circuited, `cfalse` with no selector handles everything else by echoing `false` and discarding the line.
Shaves four characters off the `expr` solution: Ignoring length of the fixed string, which appears once in each, it's 25 characters, vs. 29 for `expr`. It also has similar flexibility (it's not just `true` or `false`, you can use *mostly* arbitrary string outputs).

Given a starting time and a category, output how many minutes should be added to the start time, for it to reach the closest (forward) time of the given category.
*For example:* if the start time is `14:47` and the category is `palindrome`, the smallest time after `14:47` in the palindrome category is `15:51`, so the output is `64` minutes (because 14:47 + 64 minutes = 15:51).
## Challenge Rules:
* As you may have noted: the times in the 'All the same' category are excluded from the 'Pair' and 'Palindrome' categories, even though they are technically also pairs/palindromes.
* We only look forward when we go to the closest time. So in the example above the output is `64` (time `15:51`) and not `-6` (time `14:41`).
* You may take the times in any reasonable format. May be a string, a (Date)Time-object, a pair of integers, etc.
* You may use any *reasonable* distinct input-values for the four categories. (Keep in mind [this forbidden loophole](https://codegolf.meta.stackexchange.com/a/14110/52210)!) May be four integers; may be the category-names as strings; may be an enum; etc.
* If the input-time is already valid for the given category, the result is `0` (so we won't look for the next one).
* We use an `A:BC` pattern for single-digit hours, so they won't be left-padded with a `0` to `0A:BC`.
## General Rules:
* This is [code-golf](/questions/tagged/code-golf "show questions tagged 'code-golf'"), so the shortest answer in bytes wins.
Don't let code-golf languages discourage you from posting answers with non-codegolfing languages. Try to come up with an as short as possible answer for 'any' programming language.
* [Standard rules apply](https://codegolf.meta.stackexchange.com/questions/2419/default-for-code-golf-program-function-or-snippet/2422#2422) for your answer with [default I/O rules](https://codegolf.meta.stackexchange.com/questions/2447/default-for-code-golf-input-output-methods/), so you are allowed to use STDIN/STDOUT, functions/method with the proper parameters and return-type, full programs. Your call.
* [Default Loopholes](https://codegolf.meta.stackexchange.com/questions/1061/loopholes-that-are-forbidden-by-default) are forbidden.
* If possible, please add a link with a test for your code (e.g. [TIO](https://tio.run/#)).
* Also, adding an explanation for your answer is highly recommended.
## Test Cases:
You don't need to output the time between parenthesis. Those are just added as clarification in the test cases below. Only the integer-output is required to be output.
```
Inputs: 14:47, palindrome
Output: 64 (15:51)
Inputs: 0:00, all the same

Inputs: 0:00, increasing
Output: 12 (0:12)
Inputs: 23:59, all the same

## How?
All formulae are falsy if the criterion is met, or truthy if it's not.
If the first test is triggered, the other ones are forced to fail (this is `| !q * t` in the code). This enforces the rule about discarding pairs and palindromes with a unique digit.
### All the same
```
m % 11 | m - h && m - h * 11
```
We must have either:
* \$m\bmod 11=0\$ and \$m=h\$ (e.g. 22:22)
* or \$m=h\times11\$ (e.g. 4:44)
### Increasing
```
m - h - 12 - 10 * (282 % h ^ 6 ? h : 1)
```
We must have either:
* \$m=h+12+10\$ if \$h\in\{12,23\}\$
* or \$m=h+12+10\times h\$ if \$h\notin\{12,23\}\$
We have \$282\bmod h=6\$ if \$h\in\{12,23\}\$ and \$282\bmod h\neq 6\$ otherwise.
### Pair
```
h < 10 | h - m
```
We must have \$h\ge9\$ and \$h=m\$.
### Palindrome
```
(h > 9 ? m / 10 ^ h % 10 ? 10 : h / 10 : h) ^ m % 10
```
We must have either:
* \$h=m\bmod 10\$ if \$h\le 9\$
* or \$\lfloor m/10\rfloor = h\bmod 10\$ and \$\lfloor h/10\rfloor = m\bmod 10\$ if \$h>9\$

### Encoding
[Here](https://tio.run/##y0osSyxOLsosKNHNy09J/f9fqa7Ot66uKKmuri4los5PIyu3Dga0gbigLtEHSKWVR2fXxWvW1bnV1RWHAAUKQQrCgt0r4uqCwIoN6uo86kpT9cr06ypLIoECoXXpOXX@dXXhNVDjtECEJ4SdAMRRSv//AwA) is the uncompressed lookup string.
Each version is encoded as a single character in the printable ASCII ranges \$[40\dots48]\$ and \$[70\dots124]\$. The first range is for 2.x.x and the second one for 3.x.x and 4.x.x.
The padding character in the lookup string is `~`. Runs of 2 to 10 consecutive `~` are replaced with `1` to `9`.
**Note**: We actually don't use `~` when decompressing. Each digit \$k\$ is instead expanded to \$10^k\$ (a `1` followed by \$k\$ `0`'s). And that's why the sub-string `R~~~~~0~~H`, which includes a meaningful `0`, can be compressed as `R7H`, saving 2 more bytes.
To summarize:
| ASCII Range | Character range | Meaning |
| --- | --- | --- |
| 40 - 48 | `(` to `0` | version 2.x.x |
| 49 - 57 | `1` to `9` | compressed padding string |
| 70 - 124 | `F` to `|` | version 3.x.x or 4.x.x |
| 126 | `~` | single padding character |
To turn a character \$C\$ into the version triplet \$[a,b,c]\$, we compute \$n=\operatorname{ord}(C)+56\$ and then:
$$\begin{align}&a=\lfloor n/42\rfloor\\
&b=\cases{
\lfloor n/6\rfloor\bmod7&if $n\ge105$\\
\left(\lfloor n/6\rfloor\bmod7\right)\operatorname{xor}13&if $n<105$
}\\
&c=n\bmod6\end{align}$$

[Question]
[
Given \$n, m\ge 1\$. There are \$n\$ balls. Do \$m\$ moves, each choose a ball (maybe also the first one), and exchange with the one currently on the first place. At the end, the order of balls should be the same as the initial state.
You can either output all possibilities, or a random one provided all possibilities have non-zero probability to be outputted. You can use 0-index or 1-index. You can output a specific ball either by its initial position or by its position at the time of that move. Shortest code win.
Tests: (1-index, current position)
```
n=9, m=1 => 1
n=4, m=2 => 1,1; 2,2; 3,3; 4,4
n=2, m=3 => 1,1,1; 1,2,2; 2,1,2; 2,2,1
```
For case 1, with only 1 move we can't do any actual swap but swapping with itself. For case 2, we can swap the first ball to anywhere but the next step we have to make it back.

### How?
Filters all length \$m\$ potential instructions consisting of the alphabet \$[1,n]\$ keeping those which cause no change when applied.
In order to perform a single instructed swap the code translates this to an equivalent sequence of swaps of adjacent elements. The swaps are then applied in turn starting with an ordered list where the rightmost element is the first index and the leftmost is the last.
To swap the \$k^{\text{th}}\$ element with the \$1^{\text{st}}\$ we actually perform multiple swaps of neighbouting pairs, first to move the \$1^{\text{st}}\$ element to position \$k\$ and then to move the original \$k^{\text{th}}\$ element to to position \$1\$
For example starting with elements `GFEDCBA` (A being the "first") to swap the sixth element (`F`) with the first (`A`) we swap like so:
```
(indices): 7654321
start: GFEDCBA moving A from index 1...
swap(2,1): GFEDCAB .
swap(3,2): GFEDACB .
swap(4,3): GFEADCB .
swap(5,4): GFAEDCB .
swap(6,5): GAFEDCB done, now moving F to index 1...
swap(5,4): GAEFDCB .
swap(4,3): GAEDFCB .
swap(3,2): GAEDCFB .

’ - decrement (each instruction) e.g. [4,1,3] -> [3,0,2]

ŒB - bounce -> [[1,2,3,2,1],[],[1,2,1]]

! - factorial -> [1,2,6,2,1,1,2,1]
‘ - increment -> [2,3,6,3,2,2,3,2]
-> this is an equivalent set of instructions swapping neighbouring pairs in
turn, as lexicographical permutation indices.
⁹ - right argument = [1..n]

This generates all move sequences and selects the right ones by doing the swapping. Instead of directly swapping values (which would probably be shorter), this calculates the index of the permutation that does the right swap.
For a list of length \$t\$ the permutation that swaps the first with the \$n\$-th value has index
$$
(n-1) \cdot (t-1)! \, + \sum\_{i=t-n+1}^{t-2} i!
$$
(Uses 1-indexing, Related OEIS sequence: [A211369](https://oeis.org/A211369))
This is calculated by `¹<!y*¹ÍLRyDĀ-£!O+`, where `¹` is \$t\$ and `y` is \$n-1\$. The sum part is quite annoying to compute, because all the range builtins don't want to return empty lists.

Thanks to alephalpha's [now-deleted answer](https://codegolf.stackexchange.com/a/235713/81203) for the idea to swap values instead of positions.
Swapping the positions \$1\$ and \$x\$ of the \$\text{position}\to\text{ball}\$ list is equivalent to swapping the values \$1\$ and \$x\$ of the \$\text{ball}\to\text{position}\$ list.
The list that's being mutated isn't actually `1..n`, but it contains all numbers in the range all the same.

### How?
Instead of storing \$[0,1,\dots,n-1]\$ into the reference array, we store the actual value at a given position XOR'ed with the expected value.
This makes the initialization and the final test easier and shorter to write because we start with an array filled with \$0\$'s and expect to end up with the same configuration. (In the JS code, we actually start with an array filled with undefined values and test that there's no truthy value in the final one.)
To exchange \$A\_0\$ and \$A\_j\$, we do:
$$\cases{A\_j\leftarrow A\_0\operatorname{xor}j\\
A\_0\leftarrow A\_j\operatorname{xor}j
}$$
The implementation is a bit freaky. Within a recursive call to \$g\$, we pass the current instance of \$A[\:]\$ and then simultaneously update \$A[0]\$, update \$A[j]\$ and set \$A[\:]\$ to a new instance consisting of a copy of itself before the changes are applied, so that the array is restored to its initial state after the call:
```
g(…, A, …, [A[j], A[0], A] = [A[0] ^ j, v ^ j, [...A]])

[Question]
[
Consider the integer set \$S = \{3, 5, 6, 7\}\$. If we list all \$2^n\$ subsets of \$S\$ (its powerset) and calculate their sums, we get
$$
\mathcal{P}(S) = \{\emptyset, \{3\}, \{5\}, \{6\}, \{7\}, \{3, 5\}, \{3, 6\}, \{3, 7\}, \{5, 6\}, \{5, 7\}, \{6, 7\}, \{3, 5, 6\}, \{3, 5, 7\}, \{3, 6, 7\}, \{5, 6, 7\}, \{3, 5, 6, 7\}\} \\
\sum\_{s \in \mathcal{P}(S)} s = \{0, 3, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 18, 21\}
$$
You'll note that this set of sums is distinct - no element is repeated. We'll say that \$S\$ is a **distinct subset sum set**. Note that we're only considering sets containing positive integers for this.
In fact, for \$n = 4\$, \$k = 7\$ is the smallest positive integer such that there is a set \$S\$ containing \$n\$ distinct elements from the set \$\{1, 2, ..., k\}\$ and that \$S\$ is a distinct subset sum set. The values of \$k\$ for \$n = 0, 1, 2, 3\$ are:
| \$n\$ | \$k\$ | \$S\$ |
| --- | --- | --- |
| \$0\$ | \$0\$ | \$\emptyset\$ |
| \$1\$ | \$1\$ | \$\{1\}\$ |
| \$2\$ | \$2\$ | \$\{1,2\}\$ |
| \$3\$ | \$4\$ | \$\{1,2,4\}\$ |
For any given \$n\$, we can say that \$2^{n-1}\$ is an upper bound, as the set \$\{2^0, 2^1, ..., 2^{n-1}\}\$ is always a distinct subset sum set.
However, as shown above, this upper bound can be improved. In fact, one of the current best upper bounds is the Conway-Guy sequence ([A005318](https://oeis.org/A005318)), given by:
$$
a\_0 = 0, a\_1 = 1\\
a\_{n+1} = 2a\_n - a\_{n - \lfloor 1/2 + \sqrt{2n} \rfloor}
$$
However, it's been shown that \$a\_{67} = 34808838084768972989\$ can be improved as a bound to \$34808712605260918463\$, so the Conway-Guy sequence is currently only an upper bound (and a non-optimal one at that), rather than the exact terms. The exact terms are given by [A276661](https://oeis.org/A276661).
This sequence has only been proven to be optimal up to \$n = 9\$. Your task is to improve this.
Your program should take a non-negative integer \$n\$ and output the smallest integer \$k\$ such that there exists a distinct subset sum set \$S\$ such that, for all elements \$S\_i\$, \$1 \le S\_i \le k\$. Note that this is *not* the Conway-Guy sequence; if given \$n = 67\$ as an input, the output should not be \$34808838084768972989\$.
Your program may fail *practically* due to integer constraints (e.g. if the output exceeds your language's integer maximum), but should work *theoretically* for all \$n\$.
This is [code-golf](/questions/tagged/code-golf "show questions tagged 'code-golf'"), so the shortest code in bytes wins.

* it can produce the correct output for a value \$x > 9\$ within a minute (time using TIO if possible), and

The bounty will be awarded to the answer which can do this for the highest \$x\$. The amount I'll award will depend on the exact value of \$x\$ (e.g. \$x = 20\$ will be awarded more than \$x = 10\$), but it will be at least 150 reputation. Once someone can produce the output for \$x = 10\$, I'll wait 2 weeks for any answers to try to beat it, then start the bounty.

[Question]

There are 4 regular polygons that we can construct using ASCII art:
```
. . .
. . . . . . .
. . . . . . . . . . . . .
. . . . . . . . . . . . . . .
. . . . . . . . . . . . . . .
. . . . . . .
. . .
```
That is, a triangle, a square, a hexagon and an octagon.
Your task is to take two inputs and produce the corresponding ASCII art polygon.
## Input
The two inputs will be:
* A string/list of printable ASCII characters (i.e. with code points in the range \$33\$ (`!`) to \$126\$ (`~`)
* An indicator as to which polygon you should output. This indicator can be any \$4\$ distinct and consistent values (e.g. `1234`, `ABCD`, etc.), but each must be only one character long, to avoid any exploitation of this input.
The string will be a perfect fit for the polygon, meaning that, if the shape to be outputted is:
* A triangle, then the length of the string will be a [triangular number](http://oeis.org/A000217)
* A square, then the length of the string will be a [square number](http://oeis.org/A000290)
* A hexagon, then the length of the string will be a [centered hexagonal number](http://oeis.org/A003215)
* An octagon, then the length of the string will be an [octo number](http://oeis.org/A079273)
The string may have repeated characters, but will always fit the appropriate lengths for the given shape/sequence, so there is no need to worry about too many/few characters.
## Output
You should output a shape, indicated by the second input, in the format shown at the top of the challenge with the `.` replaced with the characters in the inputted string. Each character must be separated by a single space, and leading/trailing whitespace is acceptable, so long as the shape is preserved. The characters may be used in any order, but each character in the string must only appear once. For example, for a hexagon using `ABCDABC`, the following are valid:
```
A B B A
C D A A B C
B C D C
```
as each character from the string is used once. However,
```
A A A B AD
A A A A B C ABC
A A C A BC
```
are not valid (the first only has `A`, the second doesn't have a `D` and the third doesn't have spaces between characters).
This is [code-golf](/questions/tagged/code-golf "show questions tagged 'code-golf'") so the shortest code in *bytes* wins
## Test cases
These test cases use `T`, `S`, `H` and `O` to indicate which shape the output should be in. The string of characters is on the first line and the indicator on the second

A function taking 2 arguments: a string `s` and a shape `n` as a single character in hexadecimal of value `1`,`2`,`6` or `A`. It returns an array of strings.
**Explanation**
The input string is converted to an array, then joined back into a string with spaces between the characters. The length of this combined string is twice the length of the original string, minus 1. This is divided by a constant, square rooted and rounded to determine the side length `w` of the polygon to be drawn. The value of the constant is per the table below. For triangles, the square root is rounded down. For others, it needs to be rounded up, so we round down then add `k=1&~n` to correct.
```
Shape Triangle Square Hexagon Octagon
n = 1 2 6 10
```
We iterate through `h` rows of output. For the triangle and square, `h=w`. For the other shapes we need to add `w-1` for the hexagon and twice this amount for the octagon. This is done by adding `n/5*~-w`.
Each line of output is centred and padded to `w*4` characters which is enough for all cases. Chunks of `s` are removed using `slice!` and outputted. For the octagon the number of symbols to be outputted on each line is the minimum of three numbers: `w+w-1` for the centre section, `w+i` for the top section and `w+h-i-1` = `w+h+~i` for the bottom section. These formulas also work for the hexagon. Note that the numbers have to be multiplied by 2 to account for the spaces.
For the square and triangle, the width of the output is restricted to `w`. Therefore the formula for the centre section becomes `w+n/6*~-w` to cover all shapes . For the triangle, the width of the output is further restricted to `1+i`. Therefore the formula for the top section becomes `w**k+i` to cover all shapes.

## How?
The shape of each polygon is encoded as groups of 3 bits, packed into a single integer.
Each group of bits is decoded as follows:
* **bit 0**: if set, repeat \$n-1\$ times; if cleared, repeat \$n\$ times
* **bits 1-2**: if both bits are cleared, decrement the width at each iteration; if only bit 1 is set, increment the width after at iteration; otherwise, leave it unchanged
The initial width of the shape is:
$$w=\cases{
0,&\text{if $i=0$}\\
n,&\text{if $i=1$}\\
n-1,&\text{if $i>1$}
}$$
### Triangle (\$i=0\$)
```
..1
.1.1
1.1.1
```
One group: repeat \$n\$ times, increment the width → encoded as \$2\$
### Square (\$i=1\$)
```
1.1.1
1.1.1
1.1.1
```
One group: repeat \$n\$ times, leave the width unchanged → encoded as \$4\$
### Hexagon (\$i=2\$)
```
..1.1.1
.1.1.1.1
1.1.1.1.1
.2.2.2.2
..2.2.2
```
Two groups:
* group 1: repeat \$n\$ times, increment the width → encoded as \$2\$
* group 2: repeat \$n-1\$ times, decrement the width → encoded as \$1\$
Final encoding: \$2+8\times1=10\$
### Octagon (\$i=3\$)
```

### Challenge:
Your program will take two integers `n` and `k` as input, and output the smallest integer greater than (but not equal to) `n` that contains at least `k` occurrences of the digit `5`.
You can assume `1 ≤ k ≤ 15` and `1 ≤ n < 10**15`.
This is a [restricted-time](/questions/tagged/restricted-time "show questions tagged 'restricted-time'") challenge. Your program must run on [TIO](https://tio.run/) for all of the test cases and complete within 10 seconds in total.
## General rules:
* This is [code-golf](/questions/tagged/code-golf "show questions tagged 'code-golf'"), so the shortest answer in bytes wins.
Don't let code-golf languages discourage you from posting answers with non-codegolfing languages. Try to come up with an as short as possible answer for *any* programming language.
* [Standard rules apply](https://codegolf.meta.stackexchange.com/questions/2419/default-for-code-golf-program-function-or-snippet/2422#2422) for your answer with [default I/O rules](https://codegolf.meta.stackexchange.com/questions/2447/default-for-code-golf-input-output-methods/), so you are allowed to use STDIN/STDOUT, functions/method with the proper parameters and return-type, full programs. Your call. The function parameters may be taken in either order, but please specify in your answer.
* [Default Loopholes](https://codegolf.meta.stackexchange.com/questions/1061/loopholes-that-are-forbidden-by-default) are forbidden.
* You must add a link with a test for your code (i.e. [TIO](https://tio.run/#)).
* The answer header should list the score in bytes but also the total time taken for all test cases on TIO
* If your language is not on TIO, the code should finish far under 10 seconds on your machine so that you're confident it's fast enough on any reasonable computer.
* Adding an explanation for your answer is highly recommended.
### Test Cases:
```
(n, k) -> output
(53, 2) -> 55
(55, 1) -> 56
(65, 1) -> 75
(99, 1) -> 105
(555, 3) -> 1555
(557, 1) -> 558

-1 byte thanks to Robert S.
-8 bytes thanks to Giuseppe.
The `nchar(gsub(...))` part counts the number of `5`s.
A simple recursive solution would be to increment by 1 until the answer is found, but this would not meet the time restriction. To meet the time restriction, this function makes use of the fact that if there are p missing 5s, we can increment by `2*10^(p-2)` (represented as the golfier `.1^m/50`, with `m=-p`).
Note that when p=1, the increment becomes 0.2. This is OK, since after 5 steps we come back to an integer, and none of the decimal numbers encountered in the mean time have an extra 5. If instead we were to increment by `5*10^(p-2)` or by `1*10^(p-2)`, then we would find f(24, 1)=24.5 instead of 25 for example.

This works by
1. working out the maximum of the number of digits in the input plus one and `k`, and making a number with that many fives
2. Subtracting the input from that number
3. Generating all of the suffixes of that number
4. Also generating all the powers of ten from 1 up to the next one greater than the input
5. Adds each of the numbers in 3 and 4 to the input
6. Removes answers with too few 5’s
7. Filters out the input from the answers
8. And returns the minimum

This is \$\mathcal{O}(k)\$, (system time .008 on TIO) and has golfed well with some advice from ASCII-only.
The algorithm is to round up each digit (starting from the least-significant one) to the nearest value of 5 until the new number's decimal representation has the desired count.
The original approach used an abortable (D=iter(range(k)) and list(D) at work here) list comprehension, but @ASCII-only has convinced me that will never win code-golf. I dislike recursion, but if the algorithm is written to minimize recursion-depth, then a future compiler/interpreter will be smart enough to re-implement it as a while loop.

Explanation:
```
.+$
*
```
Convert `k` to unary.
```
^.+
$.(*__
```
Increment `n`. The `*` repeats its right argument (here the first `_` character) the number of times given by its left argument (which, as here, defaults to the match). This results in a string of that length. The `$(` (the `)` is implied) then concatenates that with the second `_` and the `.` causes the resulting length to be taken. (Actually Retina 1 is cleverer than that and just performs the calculation on the underlying lengths in the first place.)
```
/((5)|.)+¶(?<-2>_)+$/
```
Test whether enough `5`s can be found in `n` to match the `_`s of the unary representation of `k`. This test has been golfed and would be three times faster with `^` added after the initial `/` and faster still if `[^5]` was used instead of `.`.
```

Until the test passes...

[Question]
[
In this task you are given an odd number of white balls and the same number of black balls. The task is to count all the ways of putting the balls into bins so that in each bin there is an odd number of each color.
For example, say we have 3 white balls. The different ways are:
```
(wwwbbb)
(wb)(wb)(wb)
```
for the two different possibilities.
If we have 5 white balls the different ways are:
```
(wwwwwbbbbb)
(wwwbbb)(wb)(wb)
(wwwb)(wbbb)(wb)
(wb)(wb)(wb)(wb)(wb)
```
You can take the input, which is a single integer, in any way you like. The output is just a single integer.
Your code must be fast enough so that you have seen it complete for 11 white balls.
You can use any language or library that you like.

# Python 3, 108 bytes

C=lambda l,r,o=():((l,r)>=o)*l*r%2+sum(C(l-x,r-y,(x,y))for x in range(1,l,2)for y in range(1,r,2)if(x,y)>=o)
```
Recursively enumerates all sets, making sure to not get duplicates by always generating the sets in order. Reasonably fast when memoized using `C = functoools.lru_cache(None)(C)`, but this is not necessary for `n = 11`.
Call `C(num_white, num_black)` to get your result. First couple of `n`:
```
1: 1
3: 2
5: 4
7: 12
9: 32
11: 85
13: 217
15: 539
17: 1316
19: 3146
21: 7374
```
To generate the results:
```
def odd_parts(l, r, o=()):
if l % 2 == r % 2 == 1 and (l, r) >= o:
yield [(l, r)]
for nl in range(1, l, 2):
for nr in range(1, r, 2):
if (nl, nr) < o: continue
for t in odd_parts(l - nl, r - nr, (nl, nr)):
yield [(nl, nr)] + t
```
E.g. for (7, 7):
```
[(7, 7)]
[(1, 1), (1, 1), (5, 5)]
[(1, 1), (1, 1), (1, 1), (1, 1), (3, 3)]

Computing `f(11)` needs a bigger stack size, the error message will tell you how to increase it. It's more efficient (but less golfy) to replace the two `n` that appear as second arguments to `prod` with `(n-1)/2`.

[<< Prev](https://codegolf.stackexchange.com/questions/149746/advent-challenge-2-the-present-vault-raid) [Next >>](https://codegolf.stackexchange.com/questions/149861/advent-challenge-4-present-assembly-line)
Unfortunately, Santa was not able to catch the elves in time! He has to go back to manufacturing presents now. Since the elves are definitely not Santa's slaves, he has to figure out the expenses for how much to pay them.
# Challenge
Given some information for the presents, determine the cost of manufacturing all of them.
Each present is put in a cardboard box and wrapped with wrapping paper, with a ribbon wrapped around it at the very end. The wrapping paper is magical and requires no overlap, so the amount of wrapping paper used is precisely equivalent to the surface area of the box. All presents are rectangular prisms because that way Santa can store them more compactly. The ribbon goes around in all three directions (so the length of ribbon used for wrapping is equal to the sum of the three different perimeters).
The present itself has a known cost, fortunately. Cardboard costs $1 per square meter, and wrapping paper costs $2 per square meter. (Hint: You can just multiply the surface area by 3 :P). Ribbon costs $1 per meter.
# Format Specifications
The input will be given as a list of presents where each present contains the cost of the actual item and the three dimensions of the present box. Your output should be the total cost required.
To be exact, the formula for the cost of a single present with item cost `c` and dimensions `x`, `y`, and `z` is `c + 6 * (x * y + y * z + z * x) + 4 * (x + y + z)`.

### How?
The only trick used here is to factorize **(xy + xz)** as **x(y + z)** and re-use the sum **(y + z)** in the last part of the formula.
```
a => a.reduce( // for each present in a:
(s, [c, x, y, z]) => // s = sum, [c, x, y, z] = present parameters
s + // add to s:
c + // c
6 * (y * z + x * (y += z)) + // 6(yz + x(y + z))
4 * (x + y), // 4(x + (y + z))
0 // initial sum = 0
) // end of reduce()
```

[Question]
[
For this challenge you are going to make a function (your function may be a complete program) that takes a list as input and returns a permutation of that list. Your function must obey the following requirements.
* It must be deterministic.
* Composing your function with itself a variable number of times should be capable of getting a list to any of its permutations.
This is a code-golf question so answers will be scored in bytes, with less bytes being better.
## Further rules
* You may take any type of list, (`[Integer]`,`[String]`,`[[Integer]]`) as long as it
+ Can be non empty
+ Can contain distinct objects with at least 16 possible values. (You can't use a Haskell `[()]` and claim your function is `id`)
+ Can contain duplicate objects (no sets)
* You may write a program or a function, but must obey standard IO.

Takes input as an array of alphabetical characters. Returns the next permutation as another array.
```

```
### How?
This is a [generation in lexicographic order](https://en.wikipedia.org/wiki/Permutation#Generation_in_lexicographic_order) that processes the 4 following steps at each iteration:
1. Find the largest index *X* such that *a[X] < a[X+1]*
```
a.map((v, i) => v < a[i + 1] ? (t = v, x = i) : ...)
```
2. Find the largest index *Y* greater than *X* such that *a[Y] > a[X]*
```
a.map((v, i) => v < a[i + 1] ? ... : y = i > x & v > t ? i : y)
```
3. Swap the value of *a[X]* with that of *a[Y]*
```
a[x] = a[y], a[y] = t
```
4. Sort the sequence from *a[X + 1]* up to and including the final element, in ascending lexicographic order
```
a.concat(a.splice(x + 1).sort())
```

The Goldbach conjecture states that:
>
> [every even number that is greater than 2 is the sum of two primes.](http://mathworld.wolfram.com/GoldbachConjecture.html)
>
>
>
We will consider a Goldbach partition of a number **n** to be a pair of two primes adding to **n**. We are concerned with numbers is *of increasing Goldbach partition*. We measure the size of a number's Goldbach partitions by the size of the smallest prime in all of that number's partitions. A number is of increasing partition if this size is greater than the size of all smaller even numbers.
# Task
Given an even integer **n > 2**, determine if **n** is of increasing Goldbach partition, and output two unique values, one if it is and one if it is not.
This is [code-golf](/questions/tagged/code-golf "show questions tagged 'code-golf'"), so you should aim to minimize the number of bytes in your source code.

[Question]
[
### Background
The [convex hull](https://en.wikipedia.org/wiki/Convex_hull) of a finite number of points is the smallest convex polygon that contains all of the points, either as vertices or on the interior. For more information, see this [question on PGM which defines it very well](https://codegolf.stackexchange.com/questions/11035/find-the-convex-hull-of-a-set-of-2d-points?rq=1).
### Input
`N+1` 2-D coordinates (`N >= 3`) passed through `STDIN` (with other usual golf inputs allowed too) in the following format (the number of decimals can vary but you can assume it remains "reasonable" and each number can be represented as a float):
```
0.00;0.00000
1;0.00
0.000;1.0000
-1.00;1.000000
```
### Output
A truthy value printed to `STDOUT` (or equivalent) if the first point in the list (`(0.00;0.00000)` in the example above) is in the convex hull of the other N points, and a falsy value otherwise.
This is [code-golf](/questions/tagged/code-golf "show questions tagged 'code-golf'"), so the shortest solution in bytes wins.
* *Border cases*: you can return any value (but don't crash) if the point lies on the border of the convex hull (i.e. on a side or on a vertex on the outer frontier of the hull), since it is a zero probability event (under any reasonable probability).
* *Forbidden*: anything (language, operator, data structure, built-in or package) that exists **only** to solve geometric problems (e.g. Mathematica's [ConvexHull](https://reference.wolfram.com/language/ComputationalGeometry/ref/ConvexHull.html)). General purpose mathematical tools (vectors, matrices, complex numbers etc.) are allowed.
### Tests
* Should return `TRUE`: [spiralTest1-TRUE](https://github.com/ahdxb/convex-hull/blob/master/spiralTest1-TRUE), [squareTest1-TRUE](https://github.com/ahdxb/convex-hull/blob/master/squareTest1-TRUE)
* Should return `FALSE`: [spiralTest2-FALSE](https://github.com/ahdxb/convex-hull/blob/master/spiralTest2-FALSE), [squareTest2-FALSE](https://github.com/ahdxb/convex-hull/blob/master/squareTest2-FALSE)

import sys,cmath as C
p,q,*P=[complex(*eval(l.replace(*";,")))for l in sys.stdin]
A=[C.phase((r-p)/(q-p+(q==p)))for r in P]
print(max(A)-min(A)>C.pi)
```
Takes input, in the same format as the original post, through STDIN, and prints a boolean value indicating whether p is in the convex hull of P
---
## Explanation
The program tests whether the difference between the maximum and minimum (signed) angles between any point *r* in *P*, *p*, and a fixed arbitrary point *q* in *P* (we just use the first point in *P*), is less than 180°.
In other words, it tests whether all the points in *P* are contained in an angle of 180° or less, around *p*.
*p* is in the convex hull of *P* if and only if this condition is false.
---
At the cost of a few more bytes, we can use a similar method that doesn't require us to explicitly calculate angles:
Note that the above condition is equivalent to saying that *p* is outside the convex hull of *P* if and only if there exists a line *l* through *p*, such that all the points in *P* are on the same side of *l*.
If such a line exists, then there's also such a line that is incident to one (or more) of the points in *P* (we can rotate *l* until it touches one of the points in *P*.)
To (tentatively) find this line, we start by letting *l* be the line through *p* and the first point in *P*.
We then iterate over the rest of the points in *P*; if one of the points is to the left of *l* (we assume some directionality throughout, left or right doesn't really matter,) we replace *l* with the line passing through *p* and that point, and continue.
After we iterated over all of *P*, if (and only if) *p* is outside the convex hull, then all the points in *P* should be to the right of (or on) *l*.
We check that using a second pass over the points in *P*.
**Python 2, 172 bytes**
```
import sys
P=[eval(l.replace(*";,"))for l in sys.stdin]
x,y=P.pop(0)
C=lambda(a,b),(c,d):(a-x)*(d-y)-(b-y)*(c-x)>0
l=reduce(lambda*x:x[C(*x)],P)
print any(C(l,q)for q in P)
```
Alternatively, to do the same thing in a single pass, let *to-the-left-of* be a realtion between any two points, *q* and *r*, in *P*, such that *q* is to the left of *r* if *q* is to the left of the line passing through *p* and *r*.
Note that to-the-left-of is an order relation on *P* if and only if all the points in *P* are on the same side of some line passing through *p*, that is, if *p* is outside the convex hull of *P*.
The procedure described above finds the minimum point in *P* w.r.t. this order, i.e., the "leftmost" point in *P*.
Instead of performing two passes, we can find the maximum (i.e., the "rightmost" point), as well as the minimum, points in *P* w.r.t. the same order in a single pass, and verify that the minimum is to the left of the maximum, i.e., effectively, that to-the-left-of is transitive.
This would work well if *p* is outside the convex hull of *P*, in which case to-the-left-of is actually an order relation, but may break when *p* is inside the convex hull (for example, try to figure out what will happen if we ran this algorithm where the points in *P* are the vertices of a regular pentagon, running counter-clockwise, and *p* is its center.)
To accommodate, we slightly alter the algorithm:
We select a point *q* in *P*, and bisect *P* along the line passing through *p* and *q* (i.e., we partition *P* around *q* w.r.t. to-the-left-of.)
We now have a "left part" and a "right part" of *P*, each contained in a halfplane, so that to-the-left-of is an order relation on each; we find the minimum of the left part, and the maximum of the right part, and compare them as described above.
Of course, we don't have to physically bisect *P*, we can simply classify each point in *P* as we look for the minimum and maximum, in a single pass.

q=function(i,j,k)abs(det(as.matrix(cbind(d[c(i,j,k),],1))))
t=function(i,j,k)q(i,j,k)==q(1,i,j)+q(1,i,k)+q(1,j,k)
any(apply(combn(2:nrow(d),3),2,function(v)t(v[1],v[2],v[3])))
```
The script takes its inputs from STDIN, e.g. `Rscript script.R < inputFile`.
It generates all triangles from the `N` last points (the last line, `apply(combn(...` ) and checks whether the first point is in the triangle using the `t` function.
`t` uses the area method to decide if `U` is in `ABC`: (writing `(ABC)` for the area of `ABC`) `U` is in `ABC` iff `(ABC) == (ABU) + (ACU) + (BCU)`. Also, areas are calculated using the determinant formula (see [here](http://demonstrations.wolfram.com/TheAreaOfATriangleUsingADeterminant/) for a nice demo from Wolfram).
I suspect this solution is more prone to numerical errors than my other one, but it works on my test cases.

The script takes its inputs from STDIN, e.g. `Rscript script.R < inputFile`.
It generates all triangles from the `N` last points (the last line, `apply(combn(...` ) and checks whether the first point is in the triangle using the `t` function.
`t` uses the barycentric method to decide if `U` is in `ABC`: (writing `XY` for the `X` to `Y` vector) since `(AB,AC)` is a basis for the plane (except for the degenerate cases where A,B,C are aligned), `AU` can be written as `AU = u.AB + v.AC` and `U` is in the triangle iff `u > 0 && v > 0 && u+v < 1`. See for instance [here](http://www.blackpawn.com/texts/pointinpoly/) for a more detailed explanation and a nice interactive chart. *NB: to save a few chars and avoid DIV0 errors, we only compute a shortcut to `u` and `v` and a modified test (`min(u*k,v*k,k-u-v)>0`).*
The only mathematical operators used are `+`, `-`, `*`, `min()>0`.

[Question]
[
A [numeronym](https://en.wikipedia.org/wiki/Numeronym) (also known as a "numerical contraction") is when a word is shortened using numbers. A common contraction method is to use the length of the replaced substring to replace all but the first and last characters. For example, use [`i18n` instead of `internationalization`, or `L10n` instead of `localization`](https://en.wikipedia.org/wiki/Internationalization_and_localization). (The `L` is capitalized since a lowercase one looks too similar to the `1`.)
Of course, several words in the same phrase may have the same abbreviated form, so your job is to convert a group of words to their numeronyms, or in the event that there exists some *different* words with the same numeronym, your program should give a result of `A7s R4t`, short for `Ambiguous Result` (yes, I know that this result is itself an ambiguous result.)
## Rules:
* Use a program or function, and print or return the result.
* Input is taken as a single string.
* The output is a single string of space-delimited words.
* Your program need not convert words with length 3, and should not convert shorter words.
* If an `l` (lowercase ell) would occur before a `1` (one), it should be made uppercase.
* If an `I` (uppercase eye) would occur before a `1` (one), it should be made lowercase.
* Input will be printable ASCII and spaces. Words are separated by spaces.
* Shortest code wins.
## Examples:
```
A7s R4t -> A7s R4t (OR: A1s R1t, etc)
Ambiguous Result -> A7s R4t
Billy goats gruff -> B3y g3s g3f
Thanks for the Memories -> T4s f1r the M6s (one possible answer, NOT: Thnks fr th Mmrs)
Programming Puzzles & Code Golf -> P9g P5s & C2e G2f
globalization -> g11n
localizability -> L12y
Internationalization or antidisestablishmentarianism -> i18n or a26m
Internationalization or InternXXXXXalization -> A7s R4t
what is this fiddle and faddle -> A7s R4t
A be see -> A be s1e (OR: A be see)
see sea -> s1e s1a (OR: see sea)
2B or not 2B -> 2B or not 2B (OR: 2B or n1t 2B. 2 letters, don't change, don't count as ambiguous)
this example is this example -> t2s e5e is t2s e5e (same words aren't ambiguous)
l1 -> l1 (2 letters, don't change.)
I1 -> I1 (2 letters, don't change.)

# Perl, 131 120 bytes
I've added a byte for using the `-p` switch:
```
s/\B(\w+)(\w)/length($1)."$2_$1"/ge;$_="A7s R4t\n"if/(\w\d+\w)(\w+)\b.*\1(?!\2)/;s/_\w+//g;s/I1\w/\l$&/g;s/l1\w/\u$&/g;
```
### Explanation
```
# Replace internal letters with count, but keep them around for the next test.
s/\B(\w+)(\w)/length($1)."$2_$1"/ge;
# Detect ambiguous result
$_ = "A7s R4t\n" if
# Use negative look-ahead assertion to find conflicts
/(\w\d+\w)(\w+)\b.*\1(?!\2)/;
# We're done with the internal letters now

(' 'joinstring(<&(]`(rplc&('I1';'i1')&(rplc&('l1';'L1'))&({.,([:":#-2:),{:))@.(#>3:))&>&;:))
```
A looong chain of composed calls.
The first part is just a fork: a literal, `joinstring`, and a function (in J, `1 (10 + +) 2` is `(10 + (1 + 2))`).
The second part is the function. The two `rplc` calls are to replace the I/l when they could be confused.
`&` is composition, and composing an operator with a value curries. (so `3&+` gives a function that expects the 2nd argument to be added).
Finally, the last part is the function that takes the first, the length-2 (composed with stringification), and the last.
the `&>&;:` bit at the end composes this function (which should be applied to every argument) to `>` (unboxing), because `;:` (split words) returns a boxed list (so that every element can have different length).
example:
```
(' 'joinstring(<&(]`(rplc&('I1';'i1')&(rplc&('l1';'L1'))&({.,([:":#-2:),{:))@.(#>3:))&>&;:)) 'hey you baby Iooooooooneey I1'

```
These lines follow this sheme:
```
Symbol of the map | Name of the map | Level of the map | Map received from combining
```
Note that the abyss and colosseum map dont combine into higher level ones since they are the highest level.
**INPUT:**
Your input will be a a string of Symbols which correspond to the map symbols, example AAAEE which would mean 3 x crypt map and 2 x dungeon map.
**OUTPUT:**
The output will be again a string of symbols which would represent the highest possible combination of the input maps. Any combination of output is allowed as long as it features every map.
**EXAMPLES:**
```
INPUT: A
OUTPUT: A
INPUT: AAA
OUTPUT: S
INPUT: AAAEEEIII
OUTPUT: SHR or HRS or RHS or SRH
INPUT: AAAAAAAAAE
OUTPUT: WE or EW
INPUT: »»»»»
OUTPUT: »»»»»
```
**SCORING:**
Your score will be calculated through this formula, which is also actualy used in the game to calculate damage reduction:
```
POINTS = 1000 - (ByteCount / (ByteCount + 1000) * 1000);
```
**BONUS POINTS:**
1. If you add runlenght encoding to both the input and output then multiply your points by 1.2, example 3A input instead of AAA. You can omit the standard input if your answer will support this.
2. If your program will allow the actual map names as input/output then multiply your points by 1.5, you can ommit the "map" part of the map name so as a example input "**crypt crypt crypt**" and output "**sewer**" is ok. Your script also doesnt need to understand the standard input anymore if you use this method. This method also requires a space between names in both the input and output.
3. If your output string goes from lowest level map to highest then multiply your points by 1.08, maps with the same level dont need to be sorted in any particular way.
You can combine all 3 bonus points.

Tested with the following inputs:
1. `AAA`
2. `AAAEEEIII`
3. `3A3E3I`
4. `»»»»»`
5. `5»`
## General solution
Basically using regex whenever possible
```
var m = "AEIOUTNSHRDLCMWFGYPBVKJXQZÓÉÁÍÚÜÖÄËÏƌџ1234567890?!()-/\|=*†‡§[]_~{}©€<>";
var r = "SHRDLCMWFGYPBVKJXQZÓKÉÁÍÚÜÖÄËÏƌџ1234Ÿ567890?!(0)-/\|=*†‡§[]_~{}©€<©µµ»»";
var x = /([^»µ])\1{2}/;
while((p=s.match(x))!==null){
s=s.replace(x,r.charAt(m.search(p[1])));
}
```
Nothing fancy here, just replacing a match for the respective output.
### For the 1.2 Bonus
Regexing the numbers and the following letter, readable code goes like this:
```
// variable 's' is the input string
var y = /\d+/;
var z = /\d+(.)/;
var p = 0;
while((p=s.match(y)-0) !== 0) {
s=s.replace(y,Array(p).join(s.match(z)[1]));
}
```
As you can see, `s.match(y) - 0`, the matched string is subtracted by 0, that's to force a parse int without actually calling `parseInt()`.
Also `Array(p).join(s.match(z)[1])` basically joins an array of `p` **empty** elements, with the character found in the match, that's an easy way to print a letter (let's say `E`) `p` amount of times.
### For the 1.08 Bonus
Sorting algorithm:
```
s.split('').sort(function(a,b) {
return m.indexOf(a) - m.indexOf(b);
}).join('');
```

})
```
```
<form>Type your text here: <input type="text" id="input" value="3A"/></form>
<h3>Output:</h3>
<p id="a">S</p>
```
The 1.2 bonus is somewhat tricky in its formatting. If you want to input a regular number, place a `1` before it.
Basically, this scans through every character that has an upgrade (all except `µ` and `»`), then finds all sets of three of this character and replaces them with the upgraded char. Sorting after each `.replace` was the best way to make sure this always works properly, so that was an automatic bonus. The 1.2 bonus was a little harder, but I got it sorted out in 45 bytes. The 1.5 bonus is just not worth it at all, as it requires a ton more encoding and would at least double the length.
As always, suggestions are very welcome!

I have a program that generates formatted Brainfuck code. I run my program
```
./example "S"
```
and the output is
```
+[>+
<
+++
]
>--.
```
which prints S in Brainfuck.
Your objective is to write a program which accepts a string as input and outputs source code in another language which prints that string.
* The source code your program outputs must be formatted in such a way that it represents the string in ASCII art (printed horizontally, not vertically).
* The source code cannot contain the string (it may, however, contain letters that occur in the string, just not sequentially)
Otherwise,
* [Standard loopholes](http://meta.codegolf.stackexchange.com/questions/1061/standard-loopholes-which-are-no-longer-funny) apply.
* Shortest code wins.
Please title your submission with the language it is written in, the language it outputs, and the total size in bytes. Please include the output of your program when you enter the string UNCOPYRIGHTABLE.
Thanks!

Excluding unnecessary whitespace. I could easily save another hundred by changing the font data in `d[]`from hex to a string in quotemarks.
```
i,j,s,t,u,v,w,h;
char a[99],b[9999],k,d[]={0x6F,0x3B,0x5A,0xD5,0x7A,0x6A,0x5B,0x2F,0xD0,0x57,0xA1,0x1B,0xCF,0x4F,0x5F,0x6E,0x6D,0x4E,0x79,0x3A,0x1F,0x95,0x9F,0xA6,0x3D,0x76};
f(int z){
return d[a[j-1-t%(2*w*j)/w/2]-65]>>z&1?z=b[i*v/u],b[i++*v/u]=' ',z:' ';
}
main(){
for(scanf("%s",a);a[j];i++)a[j]-k?k++,b[i]='+':(b[i]='.',t+=(0xE7572B70967DB>>(a[j]*2-130)&3)+5,j++);
s=i/t+2;
u=t*(s-1);
v=i;
i=0;
w=2*s;h=2*s+1;
for(t=2*w*h*j;t--;)putchar(
t%(2*w*j)?
t/2/w/j%s?
t%s||!(t/4%s)?' ':f(t/s%4/2+t/2/w/j/s*2|7*(t/s%4==2))
:(
(t%s)&&(t/s+1&2)?f(4+t/2/w/j/s):' '
)
:10 //newline
);
}
```
This uses a calculator font (for low entropy, only one byte per letter) and a very naive Brainfuck compiler inspired by <https://codegolf.stackexchange.com/a/35801/15599> (except I use plus instead of minus.) The first `for` loop compiles the text in `a` to the string `b`, and also calculates the number of strokes required to draw the formatted code, using the 13-digit hex magic number (all characters are 5-8 strokes.)
Given the total program length and the stroke count, the number of characters per stroke is calculated (this can be very small if the characters are the same or in ascending order, and very large if the characters are in descending order.)
Most of the rest of the program is dedicated to deciding whether whitespace or one of the strokes needs to be printed. If the cursor is over a stroke square, the function `f`is called with the number of that stroke as an argument. It returns a space if that stroke is not required for the current letter, or a character from the program if it is. Because the number of characters required to complete the ASCII art may be more than the characters in the program, occasionally a space is inserted, hence the calculation `b[i * v/u]`.
There are four single strokes and four double strokes in the font, numbered as follows, which are either present or absent, depending on the letter.

[Question]
[
A certain children's game, often called "Huckle Buckle Beanstalk", is played with two players. Here is a brief description of how the game is played:
1. One player is designated the "hider", and the other the "seeker".
2. The seeker goes out of the room while the hider hides a small, pre-selected object, the "treasure".
3. The hider then attempts to look for the object while the seeker gives them helpful hints:
* If the seeker is approaching the treasure, the hider will call out "warmer!"
* If the seeker is moving away from the treasure, the hider will call out "cooler!"
4. Once the seeker finds the treasure, they announce that they have found it.
Your children want you to play this game with them, however, you are very busy answering questions on codegolf.SE instead. So, you decide to write a program to play the game with them. However, you want to use as little time as possible typing, so you try to make the program as little characters as possible.
We can define the room in which the game is played as a two dimensional toroidal square field. The coordinate `0,0` is the bottom left corner, and the coordinate `99,99` is the top right corner. The treasure is placed at some position `n,m` where `n` and `m` are both positive integers between 0 and 99 inclusive.
Your program will obtain input from the player using its inbuilt user input function (e.g. `prompt()`, `raw_input()`, etc.) If your chosen language *does not* have a user input function, take input from STDIN instead. The game will work as follows:
1. The program "hides" the treasure at a position `n,m`.
2. The program prompts the seeker to input an initial searching position. The input will come in the form `x y` where `x` and `y` are positive integers.
3. The program outputs "correct" if the initial searching position `x,y` is equal to the treasure's position `n,m` and terminates. Otherwise:
4. The program will prompt the seeker to move. The input comes in the form `a b` where `a` and `b` are *integers* that *may be negative*. This represents the *direction vector* that the seeker is moving in (`a` is the x direction and `b` is the y direction).
5. If the resultant position of the seeker is at the treasure, the program outputs "correct" and terminates. Otherwise:
6. The program outputs "cooler" if the seeker is moving away from the treasure, or "hotter" if they are moving towards the treasure.
7. Go to step 4.
The words "moving away" and "moving towards" may be ambigious. For this challenge, if the resultant position of the seeker after moving is closer to the treasure than their position before they were moving, they are moving towards the treasure. Otherwise, they are moving away. (Yes, this does mean that if the resultant and previous position are the same distance away, the program should output "cooler").
This is code golf, so shortest code wins. Ask questions if the specification is not clear.

## Javascript, 275 279
Not a winner by any means, but this should get things started. Uses a trick with `eval()` and defining `100` as a "constant" to shave off a few bytes. Ungolfed version below.
```
function D(){return Math.sqrt((x-n)*(x-n)+(y-m)*(y-m))}
H=100;
n=~~(Math.random()*H);m=~~(Math.random()*H);
P="s=prompt().split(' ')";
eval(P);
x=~~s[0];y=~~s[1];i=0;
while(x!=n||y!=m)
{
if(i)alert(i>j?"hotter":"colder");
i=D();
eval(P);
x=(x+~~s[0])%H;
y=(y+~~s[1])%H;
j=D()
}
alert("correct")
```
Edit: I fell victim to Javascript's string + number operations, hence why `D()` wasn't working properly. I also fixed a bug where "hotter" was displayed before "correct". This adds 4 bytes.

I got the input function and the idea of applying the modulo in the distance calculation rather than the location update from matsjoyce's answer.
We only need distances for comparisions: Are we at the exact location? Are we closer than before? For both of these, we get the same result comparing the **squares** of the distances as we would comparing the distances. The square-root calculation required to get the actual distance is unnecessary.

I'm sure there must be savings on the random number generation. Apart from that the key point is that reading in x & y is just treated as an offset from 0, so I only need one scanf. It does mean that I have to suppress printing hotter or cooler on the first iteration though.
Changes:
Put the location into x & y directly and then shift this back to (0,0) rather than put it in m & n and use x & y to search for it.
I realised that I was printing "hotter" and "correct" so I had to add an extra three characters here.
Rewritten the printing to put all conditions in it, saving an extra call to puts().

[Question]
[
The Haskell function [`biSp`](http://haddocks.fpcomplete.com/fp/7.4.2/20130829-168/concatenative/Control-Concatenative.html#v%3abiSp) has type signature
```
biSp :: (a -> c) -> (b -> d) -> (c -> d -> e) -> a -> b -> e
```
and (for those who prefer [combinator calculus](http://en.wikipedia.org/wiki/Combinatory_logic)) can be defined as
```
biSp g h f x y = f (g x) (h y)
```
Your task is to implement `biSp` in point-free form (equivalently: as a combinator without any lambdas) using only two primitives:
```
(.) :: (b -> c) -> (a -> b) -> a -> c
flip :: (a -> b -> c) -> b -> a -> c
```
or
```
(.) f g x = f (g x)
flip f x y = f y x
```
For those with a background in combinator calculus, these are respectively the [B and C combinators](http://en.wikipedia.org/wiki/Combinatory_logic#Combinators_B.2C_C).
You may define helper functions so long as they are point-free. Your score is the total number of terms in all right-hand-side expressions.
### Testing
You can test a Haskell solution without installing any software using Ideone. By providing an explicit type alongside the definition you ensure a compile-time error if the function is incorrect. E.g. using the `:pl` reference implementation ([online demo](http://ideone.com/QF379D)):
```
biSp :: (a -> c) -> (b -> d) -> (c -> d -> e) -> a -> b -> e
biSp = flip . ((flip . ((.) .)) .) . flip (.)
main = putStrLn "Compiled ok"
```
[Answer]
# 7 terms
We again define a helper combinator `BBQ = B B (C B)`, which has reduction rule
```
BBQ w x y z = x y (w z)
```
Then `biSp = BBQ BBQ BBQ`
```
BBQ BBQ BBQ g h f x y
= BBQ g (BBQ h) f x y
= BBQ h f (g x) y
= f (g x) (h y)
```
[Online demo](http://ideone.com/O9JzKU)
By brute force, this is the only 7-term solution and there is no smaller solution.
### 8 terms
There are a handful of 8-term solutions. Firstly, the obvious
```
C BBQ BBQ BBQ
```
which reduces in one step to `BBQ BBQ BBQ`.
Then there are three solutions of the form `X X X` with a five-term `X`:
* `X = B (B B) C B` which reduces in one step to `BBQ`
* `X = C B (C B) B` which reduces in one step to `BBQ` and allows the further extraction, for no net gain or loss, of a helper combinator `Q = C B`
* `X = C (B C (B B))`
There is one solution of the form `X X` with a six-term `X`:
* `X = C B (B B (C B))` (again, with an equivalent version which extracts `Q = C B`)
And there is one solution which can only be written in 8 terms with two helper combinators:
```
Q = C B
X = Q (Q Q B)
biSp = X X
```
[Answer]
## 9 terms
Define a helper combinator `BBQ = B B (C B)`, which has reduction rule
```
BBQ w x y z = x y (w z)
```
Then we have three options:
1. `C (B B BBQ) BBQ`
2. `B (C B BBQ) BBQ`
3. `C (B (C BBQ) BBQ)`
To show the equivalence of the first two:
```
C (B B BBQ) BBQ g h f x y
= B B BBQ g BBQ h f x y
= B (BBQ g) BBQ h f x y
B (C B BBQ) BBQ g h f x y
= C B BBQ (BBQ g) h f x y
= B (BBQ g) BBQ h f x y
```
We can then continue:
```
= BBQ g (BBQ h) f x y
```
That then gives the equivalence with the third:
```
C (B (C BBQ) BBQ) g h f x y
= B (C BBQ) BBQ h g f x y
= C BBQ (BBQ h) g f x y
= BBQ g (BBQ h) f x y
```
Finally
```
= BBQ h f (g x) y
= f (g x) (h y)
```
In Haskell this is (picking one of the options):
```
bbq = (.) (.) (flip (.))
biSp = flip ((.) (.) bbq) bbq
```

## 9 terms
This uses an intermediate combinator which I shall call `Par` for *parity*, because of the way it groups its arguments. `Par = B C (B B)` has reduction rule
```
Par w x y z = (w y) (x z)
```
Then `biSp = C (B Par (C Par))`. To demonstrate:
```
C (B Par (C Par)) g h f x y
= B Par (C Par) h g f x y
= Par (C Par h) g f x y
= C Par h f (g x) y
= Par f h (g x) y
= f (g x) (h y)

```

biSp = flip ((.) par (flip par))

$a=[preg_replace('/\S/','*',$s,-1,$n),substr_count($s,'*'),$n];

Not a lot to say about this. As there is no specification for how to handle input/output, I'm assuming variable storage. Expects the input in variable `$s` and stores the array in variable `$a`. Too bad those function names are s o long.

# Rebol, 84
```
c: s: 0 parse t[any["*"(++ s)|" "|"^/"| m: skip(change m"*" ++ c)]]reduce[t s s + c]
```
Set `t` to the text like so....
```
t: {| v |
* * * *
* * *}
```
and this would return...
```
["* * *^/* * * *^/ * * *" 7 10]
```
Ungolfed version with some notes:
```
c: s: 0 ;; "s" is star count before change, "c" is count of chars changed to stars
; so using single-char ANY rule to parse each character in "t"
parse t [
any [ ;; so "t" is made up of ANY...
"*" (++ s) | ;; "*" (if so then increment s)
" " | ;; or a space
"^/" | ;; or a newline
m: skip (change m "*" ++ c) ;; or anything else (skip)
;; (and so change to "*" & increment c)
]
]
reduce [t s s + c] ;; return array with amended text (t) and counts

## AWK, (too long)

```
I'm no `awk` master so I'm sure it can be improved. The takeaway is I had fun writing it! The struggle came with how to preserve the `newlines` from the input but not put the `, 7,10]` on a new line. That bit of logic (`NR>1{z=z "\n" $0} NR==1{z=z $0}`) cost me a lot of characters. I'd be interested to see any other `awk` approaches on that front.
I didn't provide the file at the end of the script, but obviously the usage would be `awk '{<code>}' ascii.txt`, where `ascii.txt` contains the mult-line "input".

[Question]

The challenge is rather simple:
1. Take a positive whole number \$n\$ as input.
2. Output the \$n\$th Fibonacci prime number, i.e. the \$n\$th Fibonacci number that is also prime.
Input can be as an parameter to a function (and the output will be the return value), or can be taken from the command line (and outputted there).
*Note: Using built in prime checking functions or Fibonacci series generators is not allowed.*
The first 10 Fibonacci primes are
```
[2, 3, 5, 13, 89, 233, 1597, 28657, 514229, 433494437]

f=->n,a=1,b=2{n<1?a:f[n-(2..b).find{|f|b%f<1}/b,b,a+b]}
```
Calls itself recursively, keeping track of the last two numbers in the Fibonacci sequence in `a` and `b`, and how many primes it's seen so far with `n`. `n` gets decremented when the smallest factor greater than 1 of `b`, divided by `b` and rounded down to the nearest integer, is 1 rather than 0, which happens only for prime `b`. When it's seen all the primes it's supposed to, it prints `a`, which is the most recent `b` tested for primality.

(a=b=1;Do[While[{a,b}={b,a+b};b~Mod~Range@b~Count~0>2],{#}];b)&
```
These are unnamed functions which take `n` as their input and return the correct Fibonacci prime. The shorter version uses `Divisors`. I'm not entirely sure whether this is allowed, but the other Mathematica answer even uses `FactorInteger`.
The second one doesn't use any factorisation related functions at all, but instead counts the number of integers smaller than `n` which produce `0` in a modulo operation. Even this version beats all valid submissions, but I'm sure just posting this answer will cause some people to provide competitive answers in GolfScript, APL or J. ;)

`f` is the recursive definition of Fibonacci number.
`q` detects primes.
`k` is a Fibonacci prime iff `q@f@k` is True.
For `n`=10, output is `433494437`.

This is slow.
There is a builtin for primality checking. With that included, it runs much faster, and the size drops to [19 bytes](https://tio.run/##S85KzP3/3zC@MLO6Ot5BOz63QLE2vVYrxhooaAQA) (with the restriction that the supported maximum is 12, because CJam refuses to do a primality check on a BigInt).

[Answer]
# Rust, \$3^{38\,000\,000}\$ in ~1 minute
### How it works
Given position \$n\$, we convert \$3n\$ into a base-\$\frac43\$ representation with digits \$0, 1, 2, 3\$ using a relatively fast divide-and-conquer algorithm. Iterating through these base-\$\frac43\$ digits from most to least significant gives the shifts needed to maintain a three-character sliding window of the Base64 fixed point.
For example, given position \$27\$, we compute
$$3 · 27 = (3210201101)\_{\frac43},$$
so we can jump the sliding window to the following positions (in units of \$\frac13\$ of a 6-bit character).
$$0 · \frac43 + 3 = 3, \quad
3 · \frac43 + 2 = 6, \quad
6 · \frac43 + 1 = 9, \quad
9 · \frac43 + 0 = 12, \\
12 · \frac43 + 2 = 18, \quad
18 · \frac43 + 0 = 24, \quad
24 · \frac43 + 1 = 33, \quad
33 · \frac43 + 1 = 45, \\
45 · \frac43 + 0 = 60, \quad
60 · \frac43 + 1 = 81.$$
### Usage
Accepts a base-ten integer on STDIN, and outputs a character to STDOUT.

[Question]
[
*Alternatively: Now you're checking with portals!*
*[Inspired this challenge](https://codegolf.stackexchange.com/questions/256814/knight-to-fork)*
I am somewhat of a self-declared [Chess Anarchist](https://www.reddit.com/r/AnarchyChess/). That means that when I play chess, en passant is forced (else the brick gets used), double check is mate (and [pasta](https://www.reddit.com/r/AnarchyChess/comments/ylrn7m/new_chess_rule_just_dropped/)), and all sorts of new pieces and squares are added to the game.
One such piece is the [Knook](https://www.reddit.com/r/AnarchyChess/comments/xv6q0s/white_to_move_and_mate_in_1/) (also called an "Empress" or "Chancellor" in fairy chess). It moves like a horsey and a rook combined. Another common addition are portals, like the kinds you see in the [Portal](https://store.steampowered.com/app/400/Portal/) series. They behave as you would expect.
Therefore, in this challenge, I'll be give you the position of a white knook, two black kings and an orange and blue portal. You'll give me the square I should move my knook to in order to check both the kings at once and win the game.
## Detailed Explanation of Knooks and Portals
### The Knook
Here is how a knight moves in chess:

Here is how a rook moves in chess:
[](https://i.stack.imgur.com/gwEOX.png)
Therefore, this is how a knook (knight + rook) moves in chess:
[](https://i.stack.imgur.com/96LE0.png)
In BCPS notation, it's move is `EM`. In Parlett notation, it's move is `n+, ~ 1/2`. In Betza notation, it's move is `RN`.
### Portals
From the [Portal Wiki](https://theportalwiki.com/wiki/Portals):
>
> Portals in a pair act as a direct link between one another. Anything that goes into one portal comes instantly out the other.
>
>
>
Therefore, when a piece moves into a portal, it comes out the other portal. Portals occupy a single square. There are only ever two portals on a board - one orange and one blue. Pieces cannot land on a portal, as they'd just infinitely teleport between the orange and blue portals. Pieces can also attack through portals (so a piece in a position where another piece could exit a portal would be able to be taken.)
Here's are some examples of how a rook would move through a portal. Note that it always exits the other portal in the direction it entered the first portal. Note that the rook also cannot "jump" over the portal - it has to go through if there is a portal in its way.

| --- | --- |
Here's how a knight would move through portals. Note that it can either move two squares into a portal and exit one square in a perpendicular direction, or one square into a portal and exit two squares in a perpendicular direction.
| | |
| --- | --- |
Therefore, this is how a knook would move through a portal, obeying laws of both the rook and knight portal movement rules:
| | |
| --- | --- |
## An Example
On the following board, the knook is on square `b2`, the black kings are on `d7` and `f6` and the portals are on squares `b5` and `d2`. The winning move is to move the knook through the blue portal to d5, which checks the king on `d7` via rook moves and the king on `f6` via knight moves.
On the following board, the knook is on square `c5`, the black kings are on `g3` and `h4` and the portals are on squares `f7` and `g4`. The winning move is to move the knook to `d7`, as the knook threatens to take the king on `h4` with rook moves after portal travel and threatens to take the king on `g3` with knight moves after portal travel.
On the following board, the knook is on square `f4`. The black kings are on `b8` and `d3`. The portals are on squares `f6` and `a4`. The winning move is to move the knook through the portal on `d6` and exit the portal on `a4` via a knight move (up 2, right 1). This checks both kings.
## Rules
* The positions will be given in algebraic chess notation (letter then number of the square).
* The winning move will be returned in algebraic chess notation.
* Positions can be given and returned in any reasonable and convienient format, including:
+ A list of strings (e.g. `["f4", "b8", "d3", "f6", "a4"]`)
+ A list of list of strings (e.g. `[["f", "4"], ["b", "8"], ["d", "3"], ["f", "6"], ["a", "4"]]`)
+ A list of list of numbers that represent the character codes of each string item (e.g. `[[102, 52], [98, 56], [100, 51], [102, 54], [97, 52]]`)
+ A list of string, number pairs (e.g. `[["f", 4], ["b", 8], ["d", 3], ["f", 6], ["a", 4]]`)
* Input formats and output formats don't have to match, so long as they are consistent.
* Piece positions can be taken in any order (e.g. `[portal 1, portal 2, knook, king 1, king 2]` or `[knook, king 1, king 2, portal 1, portal 2]`)
* This doesn't change much, but you can assume that the black kings will [never be on the `c2` square](https://www.reddit.com/r/chessbeginners/comments/y57x1y/i_cant_move_king_to_c2_why/).
* You may assume that there will always be at least one solution to each input.
* The board layout may start with 0 or 1 king(s) already in check. Your goal is to double check.
* Double check is strictly defined as checking both kings for this challenge. A knook checking a king through a portal and starting in check is counted as a single check only for simplicity.
* It doesn't matter if a king can capture the knook if double check is achieved. All that matters is that both kings are in check at the same time.
* If there is more than one solution, you can output one, or all of the solutions.
* Portal travel might not be required for a winning move. Double check via normal knook movement is just as valid as portal usage.
* This is [code-golf](/questions/tagged/code-golf "show questions tagged 'code-golf'"), so the shortest answer in bytes in each language wins.
## Testcases
*Input order is `[knook, king 1, king 2, portal 1, portal 2]`*

Output the square if all three were attackable, meaning that the knook can move to this square, and from this square can check both kings.

[Question]

## Introduction
The \$RADD(n)\$ operation is defined as the sum of \$n + [\$ the number whose decimal representation are the decimal digits of \$n\$ in reverse order \$]\$, see [A004086](https://oeis.org/A004086). After reversal, trailing zeros are lost. See [Reverse-Then-Add Sequence](https://mathworld.wolfram.com/Reverse-Then-AddSequence.html) and [A056964](https://oeis.org/A056964).
Not all numbers can be represented as the result of a \$RADD\$ operation.
## Examples
\$RADD(11) = 11 + 11 = 22\\
RADD(23) = 23 + 32 = 55\\
RADD(70) = 70 + 7 = 77\\
RADD(85) = 85 + 58 = 143\\
RADD(1100)= 1100 + 11 = 1111\$
## Task
We are looking for a method that determines for a given number \$m\$,
whether it can be represented with \$RADD\$, and if this is the case,
then determines an argument \$n\$ such that \$m = RADD(n)\$, symbolically \$n = RADD^{-1}(m)\$
As a convention, the larger of the two summands shall be used as result, e.g.,
\$RADD^{-1}(55) = 32, RADD^{-1}(143) = 85\$
If more than one decomposition is possible, there is no preferred choice which one is used for the output.
Since the problem comes from the OEIS sequence [A356648](https://oeis.org/A356648), only square numbers \$s=n^2\$ should be considered as a target.
## Challenge
Write a function or a program that takes an integer \$n\gt0\$ as input and returns the \$RADD\$ decompositions \$RADD^{-1}(k\_{i}^2)\$ of as many as possible further distinct square numbers \$k\_{i}^2 \ge n^2\$ as the result, such that there are no numbers \$k'\$ with \$k\_{i}<k'<k\_{i+1}\$ whose squares \$k'^2\$ are also \$RADD\$-decomposable.
As \$n\$ increases, the obvious trivial method of looping through all candidates may become infeasible.
## Winning criterion
The program that delivers the most consecutive terms represented by their decompositions after \$n=1101111\$ \$(1101111^2 = 220005934299 + 992439500022)\$ in a running time of \$300\$ s wins. If only one term is found, the combined running time to scan the range up to this term and to find its decomposition counts. [fastest-code](/questions/tagged/fastest-code "show questions tagged 'fastest-code'")
## Tests
With \$R2(n) := RADD^{-1}(n^2)\$
* Initial terms of [A356648](https://oeis.org/A356648):
```
n = {2, 4, 11, 22, 25, 33, 101, 121, 141, 202, 222, 264, 303, 307, 451, 836, 1001}
R2(2) = 2, (2^2 = 2 + 2)
R2(22) = 341, (22^2 = 484 = 143 + 341)
```
for all numbers \$n\_i\le 1001\$ not in the list no \$RADD\$ decomposition exists.
* Range \$10^5\cdots 2\times 10^5\$
```
n = {100001, 101101, 102201, 103801, 105270, 109901, 110011, 111111, 111221, 112211, 120021, 121121, 122221, 125092, 125129, 133431, 138259, 148489, 161619, 165269, 171959, 200002}
```
are the only numbers in this range for which \$RADD\$ decompositions exist.
* Some larger examples
```
n = 386221, n^2 = 149166660841 = 100166999840 + 48999661001, R2(386221)= 100166999840
n = 476311, n^2 = 226872168721 = 130002968690 + 96869200031, R2(476311) = 130002968690
n = 842336, n^2 = 709529936896 = 109600929995 + 599929006901, R2(842336) = 599929006901
```
[Answer]
# C++11 (gcc), O(log(n))
This algorithm can check, if a number n has a RADD-decomp and calculate the decomp in O(D)=O(log(n)), where D is the number of digits. It also includes a pre-test, with shorter loop.
In this way, a large range can be scanned without gaps:
TOTAL COUNT IN [1:8589934591]: 2219
(There are 2219 \$\ n\in[1:2^{33}-1]\$ such that \$n^2\$ has a RADD decomposition)
Took 153s on my pc.
The core routine uses byte-arrays to process large numbers.
With the new approach, squares are not explicitly calculated. However, adding odd numbers to get the next squares still creates some overhead. But it runs faster overall without conversion from int to byte-array.

*challenge idea by [emanresu A](https://chat.stackexchange.com/transcript/message/62441610#62441610)*
Santa has a bunch of presents wrapped in cuboid boxes of various sizes. As his sled flies above a chimney, a stack of presents will be automatically dropped through it. Santa wants to carefully choose the presents so that all of them fit into a rectangular chimney.
All presents must be center-aligned due to *magical physics* issues (i.e. placing two small presents side-by-side is not allowed). The presents can be rotated, but four of the faces must be parallel to that of the chimney. A present fits in the chimney if both its width and length are `<=` those of chimney after rotation.
## Task
Given the dimensions of the presents and the chimney, determine the maximum number of presents that fit in the chimney (i.e. sum of the presents' heights is `<=` that of the chimney). All dimensions are positive integers.
Standard [code-golf](/questions/tagged/code-golf "show questions tagged 'code-golf'") rules apply. The shortest code in bytes wins.
## Test cases
Presents and chimney are given as `[width, length, height]`.
```
Presents: [[6, 6, 4], [2, 2, 2], [2, 2, 2], [2, 2, 2]]
Chimney: [6, 6, 6]
Answer: 3
Explanation: Use three small cubes.
(Placing two or more cubes above or below the single large box is not allowed)
Presents: [[6, 10, 9], [10, 7, 6], [10, 7, 5], [10, 7, 4], [5, 10, 10]]
Chimney: [6, 5, 999]
Answer: 0
Explanation: No present fits in the chimney
Presents: [[1, 2, 6], [1, 6, 2], [2, 1, 6], [2, 6, 1], [6, 1, 2], [6, 2, 1]]
Chimney: [2, 6, 6]
Answer: 6
Explanation: All six presents can be rotated to [2, 6, 1],
which fits the chimney and takes up only 1 unit of height
Presents: [[1, 2, 6], [1, 6, 2], [2, 1, 6], [2, 6, 1], [6, 1, 2], [6, 2, 1]]
Chimney: [1, 6, 6]
Answer: 3
Explanation: All six presents can be rotated to [1, 6, 2]
Presents: [[1, 2, 6], [1, 6, 2], [2, 1, 6], [2, 6, 1], [6, 1, 2], [6, 2, 1]]

The sum of the second input is there to guarantee that there is a prefix with larger sum than the height of the chimney.

### How?
The way we generate the 6 possible rotations of a present is very hackish but pretty short. It basically goes like that:
```
for(let n = 42; n;) {
a.sort(_ => -40 % n--);
}
```
The callback function of `sort()` ignores its arguments, making the sort independent of the content of the array. The result is solely based on the current value of \$n\$, which is decremented after each iteration. More specifically, we get either \$0\$ if \$n\in\{1,2,4,5,8,10,20,40\}\$ or a negative integer otherwise.
The constants \$-40\$ and \$42\$ were chosen such that all distinct rotations are eventually generated *and* we end up with exactly \$n=0\$ when the last one has been processed.

As we all know, Santa comes down the chimney to deliver presents to good kids. But chimneys are normally full of smoke, and the Elves are worried about Santa's health. So they decide to blow the smoke out using an electronic air blower.
A chimney is modeled as a rectangular grid. The number in each cell represents the amount of smoke in the region. The left and right sides are walls, the top is open, and the air blower is blowing wind from the bottom.
```
||========||
|| |99| ||
||--+--+--||
|| | |24||
||--+--+--||
||36| |12||
||--+--+--||
|| | | ||
||--+--+--||
|| |50| ||
||^^^^^^^^||
```
Every second, the following happens in order. At any step, the smoke that goes outside of the chimney through the top is excluded from simulation.
1. The smoke is blown up one cell upwards.
2. The smoke diffuses to adjacent (4-way) cells (including outside).
* Let's say a cell contains `n` amount of smoke. Then, for each available direction, exactly `floor(n/5)` amount of smoke moves in that direction.
Given the initial state above, smoke will move and diffuse as follows:
```
After step 1:
||========||
|| | |24||
||--+--+--||
||36| |12||
||--+--+--||
|| | | ||
||--+--+--||
|| |50| ||
||--+--+--||
|| | | ||
||^^^^^^^^||
After step 2: (1 second passed)
||========||
||7 |4 |14||
||--+--+--||
||15|9 |10||
||--+--+--||
||7 |10|2 ||
||--+--+--||
||10|10|10||
||--+--+--||
|| |10| ||
||^^^^^^^^||
2 seconds passed:
||========||
||8 |12|5 ||
||--+--+--||
||11|6 |8 ||
||--+--+--||
||7 |10|6 ||
||--+--+--||
||4 |4 |4 ||
||--+--+--||
|| |2 | ||
||^^^^^^^^||
5 seconds passed:
||========||
||5 |1 |5 ||
||--+--+--||
||1 |4 |1 ||
||--+--+--||
|| | | ||
||--+--+--||
|| | | ||
||--+--+--||
|| | | ||
||^^^^^^^^||
```
This chimney is completely clear of smoke after 7 seconds.
## Task
Given a 2D grid of non-negative integers which represents the current state of smoke in the chimney, simulate the chimney as specified above and output the state 1 second later. You may assume that the chimney is at least 2 units wide and 2 units tall.
Standard [code-golf](/questions/tagged/code-golf "show questions tagged 'code-golf'") rules apply. The shortest code in bytes wins.

For instance, in the example of `[[[0, 99, 0], [0, 0, 24], [36, 0, 12], [0, 0, 0], [0, 50, 0]]]`, when the outer loop is processing the `24` and the inner loop is processing the `12`, the cells are found to be adjacent, so `12/5=2` is diffused into the outer cell but `24/5=4` is diffused out, while when the inner loop is processing the two zero cells also adjacent to the `24` there is nothing to diffuse in while `4` still diffuses out each time. This results in a net total of `24+2-4+0-4+0-4=14` in that cell.

Given a matrix of integers \$M\$, find the smallest (by number of elements) submatrix \$N\$ that contains at least one of every element present in \$M\$. (A [submatrix](https://mathworld.wolfram.com/Submatrix.html) is a “matrix formed by taking a block of the entries … from the original matrix.”)
$$
M = \begin{bmatrix}9 & 0 & -4 & 5 & 1 & -4\\
3 & -2 & 5 & 9 & -7 & 1\\
\color{blue}{0} & \color{blue}{-7} & \color{blue}{-2} & \color{blue}{5} & 9 & 5\\
\color{blue}{9} & \color{blue}{9} & \color{blue}{5} & \color{blue}{-4} & 1 & 9\\
\color{blue}{-4} & \color{blue}{1} & \color{blue}{8} & \color{blue}{3} & -4 & -4\end{bmatrix}
$$
In the above example the submatrix \$N\$, shown in blue, has at least one of every element in \$M\$, and there is no smaller submatrix with that property. Note that some elements (i.e. \$8\$) do not exist outside of \$N\$ and some elements in \$N\$ are duplicated (i.e. \$9\$).
## Input
Input will consist of a matrix \$M\$ in any convenient format. It will be at least \$1\times 1\$.
## Output
Output may be either of:
1. The submatrix \$N\$ in any convenient format. If it's returned as a 1-dimensional list its dimensions must also be given.
2. The position of \$N\$ within \$M\$, given either as the row and column positions of two of its corners diagonal from each other, or as the row and column position of one of its corners and its width and height. The answer should indicate which corners are given.
If multiple submatrices are tied for smallest representative submatrix, any one may be returned, or all may be returned.
## Rules
* [Default I/O rules](https://codegolf.meta.stackexchange.com/questions/2447/default-for-code-golf-input-output-methods/) and [standard rules](https://codegolf.meta.stackexchange.com/questions/2419/default-for-code-golf-program-function-or-snippet/2422#2422) apply. [Standard loopholes](https://codegolf.meta.stackexchange.com/questions/1061/loopholes-that-are-forbidden-by-default) are forbidden.
* This is [code-golf](/questions/tagged/code-golf "show questions tagged 'code-golf'"); shortest solution in bytes wins.

Really slow.
### Explanation
We first get the set of distinct elements of the matrix. We know that the submatrix contains at least these elements: we thus append an unknown amount of additional elements (Brachylog will try in increasing amounts until it finds a solution), we then permute them (until it finds a solution) and group them in sublists of equal lengths (trying different lengths until it finds a solution). We finally constrain this constructed sublist to actually be a sublist of the input.
Since what we’re doing is basically constructing all possible matrices which contain at least all distinct elements of the original one, and verify afterwards that it is a real submatrix of the input, you can guess why it’s really slow.
```
c Concatenate the matrix into a list
d Remove duplicate values: we get elements that must be in the submatrix
;Lc Append an unknown list L to this list
p Try any permutation
ġ. Try any grouping of elements into sublists of equal lengths; this is the output
&s Take a subset of consecutive rows of the input
\ Transpose
s Take a subset of consecutive columns of this subset
\ Transpose
This must also be the output (i.e. the output is a submatrix of the input)

What is the shortest way to convert a string containing integers separated by spaces to a list of integers?
* input : "-3 1 5 8 10"
* output : [-3, 1, 5, 8, 10]
I regularly face this situation and I wanted to know if there is a better way than (24 bytes):
```
list(map(int,s.split()))
```
[Answer]
Using *map* is way shorter than any of the ways I mentioned. You should do that.
Instead of calling `list(...)`, you should use `[*...]` (21 bytes):
```

Or even better, if you switch to python 2, `map` will always return a list. (18 bytes):

[Question]

## Introduction:
In Dutch, the words leading and suffering, being 'leiden' and 'lijden' respectively, are pronounced the same way. One is written with a "short ei", and one with a ["long ij"](https://en.wikipedia.org/wiki/IJ_(digraph)), as we Dutchman would say, but both 'ei' and 'ij' are pronounced [ɛi].
## Challenge:
Given a list of numbers, determine which (if any) are leading, and which (if any) are suffering.
A leading number is:
* A positive number
* Has at least four digits
* Is in the highest 50% of the list in terms of value
* Is still in the highest 50% of the list in terms of value, if it's 3rd digit is replaced with its 2nd digit, and it's 2nd digit-position is filled with a 0 (i.e. `1234` would become `1024`)
A suffering number is:
* A negative number
* Has at least four digits
* Is in the lowest 50% of the list in terms of value
* Is still in the lowest 50% of the list in terms of value, if it's 3rd digit is replaced with its 2nd digit, and it's 2nd digit-position is filled with a 0 (i.e. `-4321` would become `-4031`)
**Example:**
Input: `[5827, 281993, 3918, 3854, -32781, -2739, 37819, 0, 37298, -389]`
Output: leading: `[5827, 281993, 37819, 37298]`; suffering: `[-32781, -2739]`
*Explanation:*
If we sort and split the numbers into two halves, it would be:
```
[[-32781, -2739, -389, 0, 3798], [3854, 3918, 5827, 37819, 281993]]
```
There are only two negative numbers with at least four digits: `[-32781, -2739]`. Changing the digits as described above wouldn't change their position, so they are both suffering numbers.
For the largest halve, all the numbers have at least four digits: `[3854, 3918, 5827, 37819, 281993]`. Changing the digits as described above would change some of their positions however. The `3854` would become `3084`, putting it below `3798` which is in the lowest 50%, so `3854` is not a leading number in this list. The same applies to `3918` which would become `3098`, also putting it below `3798`. The other three numbers are leading, as `5827` which would become `5087`, which is still above `3798` and is in fact still at the same index of the sorted list. So `[5827, 37819, 281993]` are the leading numbers.
## Challenge rules:
* I/O is flexible. Input-list can be a list of integers, 2D digit lists, list of strings, etc. Output can be a list of lists of integers, two separated lists, two strings, both printed to STDOUT, etc.
* When determining if a number is leading/suffering, we only look at its new position of that number if only its digits are changed accordingly, not after we've applied the modifications to all numbers.
* We output the original numbers, not the modified ones.
* The numbers in the leading and suffering output-lists can be in any order.
* If the size of the input-list is odd, the number at the center doesn't belong to either halve.
* Numbers are guaranteed to remain unique after its modification. So a list like `[0, 1, 1045, 1485]` isn't a valid input-list, since `1485` would be equal to `1045` after it's modification.
## General rules:
* This is [code-golf](/questions/tagged/code-golf "show questions tagged 'code-golf'"), so shortest answer in bytes wins.
Don't let code-golf languages discourage you from posting answers with non-codegolfing languages. Try to come up with an as short as possible answer for 'any' programming language.
* [Standard rules apply](https://codegolf.meta.stackexchange.com/questions/2419/default-for-code-golf-program-function-or-snippet/2422#2422) for your answer with [default I/O rules](https://codegolf.meta.stackexchange.com/questions/2447/default-for-code-golf-input-output-methods/), so you are allowed to use STDIN/STDOUT, functions/method with the proper parameters and return-type, full programs. Your call.
* [Default Loopholes](https://codegolf.meta.stackexchange.com/questions/1061/loopholes-that-are-forbidden-by-default) are forbidden.
* If possible, please add a link with a test for your code (i.e. [TIO](https://tio.run/#)).
* Also, adding an explanation for your answer is highly recommended.

# An Séimhiú agus an tUrú
In Irish Gaelic (Gaeilge) there are a number of ways that the start of a word can be changed. The most common of these are lenition (an séimhiú) and eclipsis (an t-urú)
Lenition involves adding the letter *h* as the second letter. For example, the word "bean" (woman) would be lenited to "bhean".
Eclipsing adds a prefix to the word. The prefix is determined by the first letter of the word. For example, the word "capall" (horse) starts with a *c*. Its eclipsis is *g*. So when the word "capall" is eclipsed it becomes "gcapall".
## Challenge
Write a function or program that takes a word and returns both its lenited and eclipsed forms.
### Lenition
Only words beginning with:
```
b
c
d
f
g
m
p
s
t
```
are lenited. Words beginning with other letters are not changed.
**Some examples:**
```
bean bhean
capall chapall
Sasana Shasana
lón lón
Ífreann Ífreann
```
### Eclipsis
If a word starts with any of the following letters, it is prefixed by its respective eclipsis:
```
Letter Eclipsis
b m
c g
d n
f bh
g n
p b
t d
```
Words that don't start with those letters remain unchanged.
**Examples:**
```
bean mbean
capall gcapall
cailín gcailín
doras ndoras
fuinneog bhfuinneog
Gaeilge nGaeilge
Sasana Sasana
```
There are other changes that can happen to the start of a word, but we'll just focus on these ones.
## Rules
The input is only one word. Words will only contain `a-z`, `A-Z` or the *fada* vowels `á`, `Á`, `é`, `É`, `í`, `Í`, `ó`, `Ó`, `ú` and `Ú`.
To make it a bit more simple the word itself doesn't necessarily need to be an Irish word, just that it is treated like one in the code. So inputting `delta` should return `dhelta` and `ndelta`.
For this challenge you can assume that the input words have not already been lenited or eclipsed (in Irish, a word is only lenited or eclipsed once. You would never end up with "bhhean" or "ngcapall").
[Standard rules apply](https://codegolf.meta.stackexchange.com/questions/2419/default-for-code-golf-program-function-or-snippet/2422#2422), including [the default I/O rules](https://codegolf.meta.stackexchange.com/questions/2447/default-for-code-golf-input-output-methods/). Similarly, [default loopholes are forbidden](https://codegolf.meta.stackexchange.com/questions/1061/loopholes-that-are-forbidden-by-default).
Finally, this is [code-golf](/questions/tagged/code-golf "show questions tagged 'code-golf'") so shortest answer in bytes wins.
## Test cases
```

capall chapall gcapall

### How?
We define the following lookup table:
```
A = [ ...'2n1111gbnd1m1', 'bh', 2 ]
// 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14
A = [ '2', 'n', '1', '1', '1', '1', 'g', 'b', 'n', 'd', '1', 'm', '1', 'bh', 2 ]
```
where:
* a single character (or the string *"bh"*) is used for eclipsis; all letters that trigger eclipsis also trigger lenition
* \$1\$ means that there's no eclipsis and no lenition
* \$2\$ means that there's no eclipsis but there is lenition
The first letter of the input word is converted from Base30 to decimal, multiplied by \$17\$ and then reduced with a modulo \$22\$. The result is used to pick the correct value from \$A\$.
Any result above \$14\$ yields *undefined*, and so does any letter in the range **u-z** or any fada vowel. An undefined value is interpreted the same way as \$1\$ (no eclipsis, no lenition).
```
1st letter | from Base30 | * 17 | mod 22 | A[n]
-------------+-------------+------+--------+-----------
a | 10 | 170 | 16 | undefined
b | 11 | 187 | 11 | 'm'
c | 12 | 204 | 6 | 'g'
d | 13 | 221 | 1 | 'n'

[Question]
[
In [Map inputted ASCII characters](https://codegolf.stackexchange.com/q/124306/61563), I asked you to .. map inputted ASCII characters. This time, you will do the opposite, by immediately mapping all ASCII characters, and then mapping spaces over them.
This program will have practical uses, such as seeing what characters you have left in a [restricted-source](/questions/tagged/restricted-source "show questions tagged 'restricted-source'") challenge submission.
# Challenge
Your job is to write a program that *un*-maps inputted ASCII characters. As soon as the program is run, it will display *this exact map* (except color, font, size, etc.):
Each time the user inputs a printable ASCII character, you will print a space over it.
[](https://i.stack.imgur.com/iR50B.gif)
# Rules
* The initial output must be exactly as shown in the first image above: a 6x16 grid with ASCII characters in their respective positions, with the space (32) at the top left and the tilde (126) at one character left from the bottom right.
* Your program only needs to display the printable ASCII characters, `0x20` to `0x7E`.
* Your program must not terminate and continue to print spaces over characters until all printable ASCII characters have been overwritten. From here, your program can either terminate or run off into Neverland.
* Your reverse map must be updated in realtime (as soon as it receives user input).
* If your program does not read input silently, it must put the cursor out of the way, so the text won't get in the way of the map.

This has no cursor whatsoever. I also have a 47 byte version which might be valid, depending on what is meant by "put the cursor out of the way, so the text won't get in the way of the map":
```
8000- 20 58 FC A9 A0 20 1B 80
8008- 20 ED FD 1A C9 FF D0 F5
8010- 20 0C FD 20 1B 80 20 57

8020- 29 0F 0A 85 24 68 4A 4A
8028- 4A 4A 20 5B FB 68 60
```
This puts a cursor at the character after the character you type (which is the space between characters), so it won't overwrite any of the actual characters in the map. Whether this is valid or not is up to the creator of the challenge.

An [error quine](https://codegolf.stackexchange.com/q/36260/62131) (also known as a "Kimian quine") is a program which, when compiled or run, causes the compiler/interpreter/runtime to print an error message that has identical text to the program itself, and nothing else. For the purposes of this challenge, we're defining "error" broadly, to include warnings too.
## Task
In this challenge, we're looking for a [quine](/questions/tagged/quine "show questions tagged 'quine'") which is *also* an error quine. When executed, the program must print its own source code normally (i.e. not as an error/warning message); this must be a [proper quine](http://meta.codegolf.stackexchange.com/q/4877/62131) (i.e. some part of the program must encode a different part of the output). Additionally, compiling and executing the program must *also* cause the program's source code – and nothing else – to be printed as error or warning messages by the implementation. (Note that this means that you will not be able to use compile-time errors, in languages where those prevent the program from executing normally.) So in other words, the program's source code will be printed twice, once via each method.
## Clarifications
* In most cases, it'll be obvious what is and isn't an error/warning message; we aren't distinguishing between the two here. In ambiguous cases, define an error/warning message as any text that's output by the implementation either: 1. as a consequence of something other than executing a command (or whatever the closest equivalent is in the language); or 2. that wasn't part of the input to the command that produced it as output.
* The error/warning part of the quine doesn't need to be a proper quine (although in most cases it will be by chance, as most error and warning messages contain considerable amounts of fixed text).
* It's acceptable for the program to output multiple errors/warnings, which form the program's source when concatenated together. It's not acceptable to output errors/warnings that don't appear in the source.
* Unlike in many challenges, the switches given to the compiler, and the program filename, are likely to be highly relevant in this challenge. Given that the challenge may not be possible otherwise, I'm willing to be flexible here, although if you run the implementation in an unusual way, remember that PPCG rules charge a byte penalty for doing so (equal to the number of additional characters that you'd need to add on the command line over the shortest "normal" way to run a program), and thus you'll need to specify the size of the penalty in your post. (For example, if the interpreter you're using reads the program from a file, and has no particular restrictions on the filename, the shortest normal way to run the program would be from a file with a 1-character filename; thus, if you need a 100-character filename to make your program work, you'd incur a byte penalty of +99.)
* The compiler/interpreter version you use may well be relevant, so as part of your submission, please state a specific compiler or interpreter on which your program works, and which version is required. (For example, a C submission might state "C (gcc 6.2.0)" in the header.)
* Note that this task may not be possible in all languages. In the languages where it is, the easiest method will likely be to find an error or warning message for which it's possible to customize some subset of the text (via changing the name of something that gets quoted in the message; filenames are a common choice here, but not the only one). I'll be particularly impressed (and surprised) if someone finds a way to do this using *only* error and warning messages whose text is fixed.
## Victory condition
This is a [code-golf](/questions/tagged/code-golf "show questions tagged 'code-golf'") challenge, so an entry is considered to be better if it has a smaller byte count. As such, once you've got your program working at all, you want to optimize it to bring the number of bytes down as far as possible. (However, don't be discouraged if there's already a shorter entry, especially if it's in a different language; what we're really looking for here is to shorten a particular algorithm or idea behind a program as much as possible, but seeing multiple solutions in different languages or that rely on different principles is always worthwhile.)

# JavaScript (Firefox 50), 153 bytes
```
Error: "Error: 1.replace(/.+/,x=>{alert(x=x.replace(1,uneval(x)));throw x.slice(7)})".replace(/.+/,x=>{alert(x=x.replace(1,uneval(x)));throw x.slice(7)})
```
### Explanation
The idea here was to start with the [most easily modifiable JS quine](https://codegolf.stackexchange.com/a/62466/42545) I've found yet:
```
".replace(/.+/,x=>alert(uneval(x)+x))".replace(/.+/,x=>alert(uneval(x)+x))
```
The `throw` keyword is a simple way to make it throw its own code as well:
```
".replace(/.+/,x=>{alert(x=uneval(x)+x);throw x})".replace(/.+/,x=>{alert(x=uneval(x)+x);throw x})
```
However, there's a slight problem: Firefox prepends the thrown message with `Error:`. Fortunately, `Error: mycode` is actually valid JavaScript! (To learn more about this, [visit MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/label).)
```
Error: ".replace(/.+/,x=>{alert(x=uneval(x)+x);throw x})Error: ".replace(/.+/,x=>{alert(x=uneval(x)+x);throw x})
```
Oops, this alerts the wrong thing:
```
".replace(/.+/,x=>{alert(x=uneval(x)+x);throw x})Error: ".replace(/.+/,x=>{alert(x=uneval(x)+x);throw x})Error:
```
Since the quotation mark is no longer at the start of the code, `uneval(x)+x` won't give us the correct result. The best way to fix this is to add a placeholder in place of the nested string:
```
Error: "Error: 1.replace(/.+/,x=>{alert(x=x.replace(1,uneval(x)));throw x})".replace(/.+/,x=>{alert(x=x.replace(1,uneval(x)));throw x})
```
Uh-oh, now there's an extra `Error:` in the error message. Let's fix that by slicing the string:
```
Error: "Error: 1.replace(/.+/,x=>{alert(x=x.replace(1,uneval(x)));throw x.slice(7)})".replace(/.+/,x=>{alert(x=x.replace(1,uneval(x)));throw x.slice(7)})
```
And finally, both the output and the error message are identical to the code! I'd add a Stack Snippet, but it doesn't seem to work in a snippet in any browser.

The trailing linefeed is required.
```
s='s=%r;print s%%s;exit(s%%s)';print s%s;exit(s%s)
```
[**Try it online**](http://ideone.com/jOeSqN)
I started with a simple quine:
```
s='s=%r;print s%%s';print s%s
```
Then I added `raise` on the end to throw an `IOError`.
```
s='s=%r;print s%%s;raise IOError(s%%s)';print s%s;raise IOError(s%s)
```
Unfortunately, the traceback was causing problems (I couldn't make it go away completely), and the name of the exception was always printed in front like `IOError: <code here>`, even if I removed the traceback.
Then I found this [helpful SO answer](https://stackoverflow.com/a/41414413/2415524) and modified it for my purposes.
Then I found that I can skip creating my own class and can just use `sys.exit`, making my code much shorter.

[Question]
[
Let's parse and process Key-Language! Given the input of a sequence of keyboard keypresses and/or special keys, write a program, function, etc. that outputs the product when all the actions are processed based on the following keyboard:
```
+-------------------------------------------------------+
| ~ | ! | @ | # | $ | % | ^ | & | * | ( | ) | - | + | |
| ` | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 0 | _ | = |Del|
+-------------------------------------------------------+
|TAB| q | w | e | r | t | y | u | i | o | p | [ | ] | \ |
| | Q | W | E | R | T | Y | U | I | O | P | { | } | | |
+-------------------------------------------------------+
|CAPS | a | s | d | f | g | h | j | k | l | ; | ' | RET |
| | A | S | D | F | G | H | J | K | L | : | " | |
+-------------------------------------------------------+
| SHIFT | z | x | c | v | b | n | m | , | . | / | SHIFT |
| | Z | X | C | V | B | N | M | < | > | ? | |
+-------------------------------------------------------+
| |
| SPACEBAR |
+-------------------------------------------------------+
```
The keys that output actual characters *not* consisting of whitespace and *are* able to be modified by other keys will be known as "character keys", and those that modify the output of other keys or output whitespace will be known as "special keys". The alphabet character keys, which will be shown in the input with uppercase letters, can be modified with either `Shift` or `Caps Lock` to produce uppercase letters, and the rest of the character keys can only be modified with `Shift` to produce their alternate characters. Therefore `A` in the input corresponds to the `a A` character key, whose normal output is `a` and whose modified output, obtainable with either the `Shift` or `Caps Lock` key, is `A`. On the other hand, `/`, which corresponds to the `/ ?` character key, has a normal output of `/` and a modified output of `?` obtainable with only with `Shift` this time.
# Rules
* The input will *always* be a *string* consisting of a sequence of the character keys and special keys. The full special key to string mapping for the input (i.e. the format they are guaranteed to be in the input) and their corresponding actions/outputs are as follows:
+ `<DEL> -> Delete the previous character (including whitespace). If called when string is empty, nothing happens. If called 2 or more times in a row, 2 consecutive deletes happen. For instance, "RE<DEL><DEL>" should return an empty string ("") and also "R<RET><DEL><DEL>E" should return just "E".`
+ `<CAPS> -> Enable Caps Lock until <CAPS> appears again, upon which it is disabled, although it is not guaranteed to be disabled by the end of the input. Enabling this only modifies the upcoming alphabet keys resulting in them outputting only uppercase letters. For instance, "<CAPS>RE<CAPS>" results in the output "RE", but <CAPS>.<CAPS> would still result in a ".".`
+ `<RET> -> Add a new line.`
+ `<SPC> -> Add a single blank space.`
+ `<TAB> -> Add 4 spaces.`
+ `<SHFT> -> Shift is held down resulting in the alternate character of the upcoming keypress to be output, after which the key is released. For instance, "<SHFT>A" results in the output "A", "<SHFT>1" results in the output "!", and "<SHFT>1234" results in the output "!234" as only the first upcoming keypress is modified and nothing else. It is guaranteed that a character key will succeed a <SHFT>. Therefore, <SHFT><SPC> is not a possible input.`
* An empty string is also possible as input, for which the output should be nothing.
* The use of *any* built-in that solves this problem directly is disallowed.
* The use of standard loopholes is disallowed.
# Test Cases
Presented in the format `Actual String Input -> Actual String Output` followed by an explanation for a few.
1. `1<SHFT>2<TAB><CAPS>R.KAP.<SPC><SHFT>123 -> 1@ R.KAP. !23`
Output `1` as the `1` key is pressed without a toggle, then Shift is held down and the `2` key is pressed resulting in the `@` output. Then the Shift key is released and Tab is pressed, resulting in a 4 spaced indentation. Following up, the Caps Lock key is pressed, after which the `R`,`.`,`K`,`A`,`P`, and `.` keys are pressed, resulting in the output `R.KAP.`. Finally, a single space is output followed by shift resulting in `!23` being output when the `1`,`2`, and `3` keys are pressed at the end.
2. `<SHFT>ABCDEFG<SHFT>HIJK<SHFT>1<SHFT>2<SHFT>3<SHFT>4567890 -> AbcdefgHijk!@#$567890`
The Shift key is held down followed by the `A` key, resulting in the output `A` followed by the output `bcdefg` when the `B-G` keys are pressed. Then, the Shift key is held down again succeeded by the `H` key, after which the output is `H`, followed by `ijk` when the `I-K` keys are pressed. Finally, the `1-4` keys are all modified as shift is held down before each keypress resulting in the output `!@#$` finished off by `567890` when the `5-0` keys re pressed.
3. `<CAPS>THIS<SPC>IS<SPC>IN<SPC>ALL<SPC>CAPS<CAPS><SPC>NOW<SPC>THIS<SPC>IS<SPC>IN<SPC>ALL<SPC>LOWERCASE -> THIS IS IN ALL CAPS now this is in all lowercase`
4. `<TAB><SPC><TAB><SHFT>1 -> !`
5. `<CAPS>WWW<CAPS>.CODEGOLF.STACKEXCHANGE<SHFT>.COM -> WWW.codegolf.stackexchange>com`
6. `PROGRAMMING<CAPS><SPC>IS<SPC><CAPS>AWESOME -> programming IS awesome`
7. `<DEL><RET><DEL><RET><DEL> -> "" (Empty String)`
The delete key is pressed in the beginning after which nothing happens. Then, the Return key is pressed resulting in a new line, which is deleted after the backspace key is pressed again. Finally, the same sequence (new line followed by backspace) is repeated. After all this, the output is an empty string.
8. `<SHFT>HI<SPC>HOW<SPC>ARE<SPC>YOU<SHFT>/<RET><SHFT>I<SPC><SHFT>AM<SPC>O<DEL><SHFT>GOOD<SHFT>1 -> Hi how are you?\nI Am Good!`
9. `<SHFT>,<CAPS>RET<CAPS><SHFT>. -> <RET>`
The string `<RET>` should be the *actual* string output. Thus, this should *not* output a new line.
10. `<CAPS>67890,.;'[]<CAPS> -> 67890,.;'[]`
11. `<CAPS><SHFT>A -> A`
12. `RE<DEL><DEL> -> "" (Empty String)`
13. `U<RET><DEL><DEL>I -> i`
14. `<DEL><DEL><DEL>5<DEL> -> "" (Empty string)`
15. `"" (Empty String) -> "" (Empty String)`

# 16-bit x86 machine code, 140 139 bytes
*Saved 1 byte by replacing DL with DX in the second-to-last opcode. Also corrected jump offsets in disassembly to match hex dump.*
Since the nature of the task requires some pre-initialized data, and the answer is not a full program but a function, I assume that there's a data section in the program and the linker promptly updates the address of the data. The address placeholder is denoted by '????'.
This is a hex representation of the code. The parameters are pointer to input string in SI and pointer to the output buffer in DI. Strings are assumed to be NULL-terminated.
```

[Question]
[
My preferred way to approximate a derivative is the central difference, its more accurate than forward difference or backward difference, and I'm too lazy to go higher-order. But the central difference requires a data point on either side of point you are evaluating. Normally this means you end up not having a derivative at either endpoint. To solve it, I want you to switch to forward and backward difference at the edges:
Specifically, I want you to use a forward difference for the first point, a backward difference for the last point, and a central difference for all the points in the middle. Also, you can assume x values are evenly spaced, and focus only on y. Use these formulas:
[](https://i.stack.imgur.com/kmtvZ.png)
Good luck, I'm looking forward to seeing if someone comes up with a simple rule which reproduces all 3 derivatives in the right places!
EX INPUT:
```
0.034 9.62 8.885 3.477 2.38
```
I will use FD, CD, and BD to denote which algorithm to use in which spot, so above 5 points are used to approximate derivatives using
```
FD CD CD CD BD
```
And then the calculated values would be:
```
9.586 4.4255 -3.0715 -3.2525 -1.097
```
You can assume that there will always be at least 3 input points, and you can calculate using single or double precision.
And as always, shortest answer wins.

This yields [b-a, b-a, c-b, d-c, e-d, e-d].
+2\ Add the values of all overlapping pairs.
This yields [2(b-a), c-a, d-b, e-c, 2(e-d)].
H Halve all resulting numbers.
This yields [b-a, (c-a)/2, (d-b)/2, (e-c)/2, e-d].

[Question]
[
This is based on this challenge and Geobits's/CarpetPython's idea to improve it:
[Keep your distance!](https://codegolf.stackexchange.com/questions/44781/keep-your-distance)
For this challenge, the distance between two numbers is measured on a loop, so, for example, the distance between 0 and 999 is 1. This should prevent strategies like always picking the lowest or highest number from winning almost every time. The only other change is that the lowest number that can be chosen is now 0 instead of 1.
I'll summarize it here:
* Write a function in Java, Python, or Ruby that takes three arguments:
+ the number of rounds played so far
+ the number of players
+ the numbers picked in the previous rounds, as an array of space-separated strings
* It should return an integer from 0 to 999, inclusive
* The score for a program each round is the sum of the square roots of the distances to the numbers each other program picked
* The program with the highest score after 100 rounds wins.
* One answer per person
The control program is here:
<https://github.com/KSFTmh/src/>
# Leaderboard
NumberOne, by TheBestOne, is winning.
* NumberOne - 9700
* NumberOnePlusFourNineNine - 9623
* AncientHistorian - 9425
* FindCampers - 9259
* WowThisGameIsSoDeep - 9069
* Sampler - 9014
* SabotageCampers - 8545
Apparently, my camper sabotage...er(?) doesn't work very well.
Here are the full results: <https://github.com/KSFTmh/src/blob/master/results-3>
I think this is different enough to not be a duplicate.
By the way, this is my first time asking a question on Stack Exchange, so let me know if I'm doing something wrong.
[Answer]
# Python 2, Sampler
This entry is based on the same code for [Keep your distance, Sampler entry](https://codegolf.stackexchange.com/a/44798/31785). I hope it will do better here where the 1 and 999 advantages do not exist.
Out of a list of places, choose the one that is farthest away from recently used
numbers, ignoring the previous turn (because other entries may predict based on just the previous turn).
```
def choose(turn, players, history):
sample = map(int, (' '.join( history[-5:-1] )).split())
def distance(x):
return sum(min(1000-abs(x-y), abs(x-y))**0.5 for y in sample)
score, place = max((distance(x), x) for x in range(1000))
return place
```
[Answer]
# Number OnePlusFourNineNine, Java
```
public static int choose(int round, int players, String[] args) {
return 500;
}
```
The logic is really simple. Unless someone finds a real algorithm which takes previous scores into consideration, this answer is fairly optimized.
Now that we count the distance in a circle, the maximum distance of any two points can be 500. Now if all entries were generating random numbers (or pseudo random based on some algorithm), this answer would not have been in any advantage at all. But there is at least 1 entry which produces a constant answer which an almost maximum distance. The makes the score come in favor of 500 as there is a fixed source of maximum distance possible in each round :)
[Answer]
# AncientHistorian - Python
It is the same algorithm from the previous one, except when calculating the potential scores it uses the circular distance. Since I'm losing horribly and can't get the controller to compile, I'm just trying a new strategy, where I use the worst from the previous rounds.
```
def choose(round, players, scores):
calc = lambda n, scores: sum([min(abs(int(i)-n), 1000-max(int(i),n)+min(int(i),n))**.5 for i in scores.split(' ')])
return min(range(1000), key=lambda n: sum([calc(n, j) for j in scores[1:]])) if round>1 else 250
```

remove.append(i)
campers=[i for i in prevchoices if i not in remove]
return random.choice(campers)
```
The campers are still winning. Let me know if you have any suggestions for this.
[Answer]
# FindCampers - Python 2
Find all the campers from the last 10 rounds and stay away from them. I'm hoping that predictors will run from me. I will now ignore my old choices.

return min(1000 - abs(x-y), abs(x-y))
pastRounds = list(map(lambda x: Counter(map(int, x.split())), previous))
me = 751
for (index, round) in enumerate(pastRounds):
round.subtract((me,))
pastRounds[index] = set(round.elements())
campers = reduce(lambda x,y: x.intersection(y), pastRounds[max(1, index-9):index], pastRounds[max(0,index-10)])

# Background
In this challenge, a *base-`b` representation* of an integer `n` is an expression of `n` as a sum of powers of `b`, where each term occurs at most `b-1` times. For example, the base-`4` representation of `2015` is
```
4^5 + 3*4^4 + 3*4^3 + 4^2 + 3*4 + 3
```
Now, the *hereditary* base-`b` representation of `n` is obtained by converting the exponents into their base-`b` representations, then converting their exponents, and so on recursively. Thus the hereditary base-`4` representation of `2015` is
```
4^(4 + 1) + 3*4^4 + 3*4^3 + 4^2 + 3*4 + 3
```
As a more complex example, the hereditary base-`3` representation of
```
7981676788374679859068493351144698070458
```
is
```
2*3^(3^(3 + 1) + 2) + 3 + 1
```
The *hereditary base change of `n` from `b` to `c`*, denoted `H(b, c, n)`, is the number obtained by taking the hereditary base-`b` representation of `n`, replacing every `b` by `c`, and evaluating the resulting expression. For example, the value of
```
H(3, 2, 7981676788374679859068493351144698070458)
```
is
```
2*2^(2^(2 + 1) + 2) + 2 + 1 = 2051
```
# The Challenge
You are given as input three integers `b`, `c`, `n`, for which you may assume `n >= 0` and `b, c > 1`. Your output is `H(b, c, n)`. The shortest byte count wins, and standard loopholes are disallowed. You can write either a function or a full program. You must be able to handle arbitrarily large inputs and outputs (bignums).
# Test Cases
```
4 2 3 -> 3
2 4 3 -> 5
2 4 10 -> 1028
4 4 40000 -> 40000
4 5 40000 -> 906375
5 4 40000 -> 3584
3 2 7981676788374679859068493351144698070458 -> 56761
2 3 2051 -> 35917545547686059365808220080151141317047
```
### Fun Fact
For any integer `n`, the sequence obtained by
```
n1 = n
n2 = H(2, 3, n1) - 1
n3 = H(3, 4, n2) - 1
n4 = H(4, 5, n3) - 1
....
```
eventually reaches `0`. This is known as [Goodstein's theorem](http://en.wikipedia.org/wiki/Goodstein%27s_theorem).
[Answer]
# Python 2, 55
```
H=lambda b,c,n,s=0:n and n%b*c**H(b,c,s)+H(b,c,n/b,s+1)
```
A recursive solution. Like the recursive algorithm to convert between bases, except it recurses on the exponent as well.
We split `n` into two parts, the current digit `n%b`, and all other digits `n/b`. The current place value is stored in the optional parameter `s`. The current digit is converted to base `c` with `c**` and the exponent `s` is converted recursively. The remainder is then converted the same way, as `+H(b,c,n/b,s+1)` but the place value `s` is one higher.
Unlike base conversion, hereditary base conversion required remembering the current place value in the recursion for it to converted.
For ease of reading, here's what it looks like when `b` and `c` are fixed global constants.
```
H=lambda n,s=0:n and n%b*c**H(s)+H(n/b,s+1)
```

[Question]

Your goal is to implement [Möbius inversion](http://en.wikipedia.org/wiki/M%C3%B6bius_inversion_formula), a linear operation on a sequence of numbers that is [used in combinatorics and number theory](https://www.maa.org/sites/default/files/pdf/upload_library/22/Ford/BenderGoldman.pdf). Fewest bytes wins.
**What is Möbius inversion?**
Given a (finite) integer sequence `f_1, f_2, ..., f_N`, we can compute its divisor-partial-sum `g`, whose `n`th element `g_n` is the sum of all terms `f_d` whose index `d` is a divisor of `n`.
```
g_n = sum_(d with d|n) [f_d]
g_1 = f_1
g_2 = f_1 + f_2
g_3 = f_1 + f_3
g_4 = f_1 + f_2 + f_ 4
g_5 = f_1 + f_5
g_6 = f_1 + f_2 + f_3 + f_6
...
```
The sequence `g` has the same length as `f`.
[Möbius inversion](http://en.wikipedia.org/wiki/M%C3%B6bius_inversion_formula) is the process of inverting this operation -- recovering `f` from `g`. This inverse is unique and produces an integer sequence. A explicit but complicated way to compute it is the [Möbius inversion formula](http://en.wikipedia.org/wiki/M%C3%B6bius_inversion_formula), which expresses `f_n` as a weighted sum over divisors `d` of `n`:
```
f_n = sum_(d with d|n) [μ(d) * g_(n/d)]
```
and `μ` is the [Möbius function](http://en.wikipedia.org/wiki/M%C3%B6bius_function):
```
μ(n) = 1 if n is a square-free positive integer with an even number of prime factors.
μ(n) = −1 if n is a square-free positive integer with an odd number of prime factors.
μ(n) = 0 if n has a squared prime factor.
```
**Program requirements**
Write a [function or program](https://codegolf.meta.stackexchange.com/q/2447/20260) to perform Möbius inversion. Fewest bytes wins. Built-in methods to perform Möbius inversion, do sequence convolution, compute the Möbius function (or related thing like checking squarefreeness), or solve systems of equations are not allowed.
**Input**
A sequence of integers of length at least 1. Can be any format that represents an ordered sequence: array, list, stack, token-separated string, etc. Unordered maps from the index to the element like dictionaries and functions are not OK. You're not given the length of the input sequence separately.
**Output**
Return or print the output sequence in any format, with same restrictions as input. It should be the same length as the input sequence.
**Test cases**
```
Input: [1, 2, 2, 3, 2, 4, 2, 4, 3, 4, 2, 6, 2, 4, 4, 5, 2, 6, 2, 6]

# J - 13 char

```
(%.0=#\|~/#\)
```
Here's what's going on:
* `#\` gets indices from 1 to the length of the input list, inclusive.
* `|~/` makes a table of indices modulo themselves.
* `0=` checks for equality to zero, 1 for true, 0 for false. On the table of moduli, this checks divisibility, returning a matrix like
```
1 0 0 0 0 0 0 0
1 1 0 0 0 0 0 0
1 0 1 0 0 0 0 0
1 1 0 1 0 0 0 0

1 1 1 0 0 1 0 0
1 0 0 0 0 0 1 0
1 1 0 1 0 0 0 1
```
* Finally, `%.` takes the input sequence and this matrix, and solves it as a linear system: `x` equal to `b %. A` is the solution to `Ax=b` if it exists. Our `b` is the input sequence and `A` is this divisibility matrix above.
In use: (Note that J spells its negative sign `_`)

Then I just solve the corresponding system of equations.
The command `meshgrid(x)` is primarly inteded for producing matrices like
```
1 1 1 1
2 2 2 2
3 3 3 3
4 4 4 4
```
and
```
1 2 3 4
1 2 3 4
1 2 3 4
1 2 3 4
```
which can then be used as e.g. x and y coordinates for plotting 2d functions. I just use one of them for ceating a matrix with where the k-th column has is 0 every k-th element via elementwise remainder division (modulo). `~` as the logical `not` which replaces nonzero values with zeros and vice versa, which then results in the matrix above.

[Question]
[
The [edit (or Levenshtein) distance](https://en.wikipedia.org/wiki/Edit_distance) between two strings is the minimal number of single character insertions, deletions and substitutions needed to transform one string into the other. If the two strings have length n each, it is well known that this can be done in O(n^2) time by dynamic programming. The following Python code performs this calculation for two strings `s1` and `s2`.
```
def edit_distance(s1, s2):
l1 = len(s1)
l2 = len(s2)
matrix = [range(l1 + 1)] * (l2 + 1)
for zz in range(l2 + 1):
matrix[zz] = range(zz,zz + l1 + 1)
for zz in range(0,l2):
for sz in range(0,l1):
if s1[sz] == s2[zz]:
matrix[zz+1][sz+1] = min(matrix[zz+1][sz] + 1, matrix[zz][sz+1] + 1, matrix[zz][sz])
else:
matrix[zz+1][sz+1] = min(matrix[zz+1][sz] + 1, matrix[zz][sz+1] + 1, matrix[zz][sz] + 1)
return matrix[l2][l1]
```
In this task you have to get as close are you can to computing the edit distance but with a severe memory restriction. Your code is allowed to define one array containing 1000 32-bit integers and this is to be the only temporary storage you use in your computation. All variables and data structures are to be contained in this array. In particular, you would not be able to implement the algorithm above as for strings of length 1000 as it would require you to store at least 1,000,000 numbers. Where your language doesn't naturally have 32 bit integers (for example Python) you simply need to make sure you never store a number larger than 2^32-1 in the array.
You may read in the data using any standard library of your choice without worrying about the memory restrictions in that part. In order to make the competition fair for the main part of your code, you may only use operations that are functionally equivalent to those in the C programming language and cannot use any external libraries.
To be extra clear, the memory to store the input data or used by your language's interpreter, JVM etc. does not count towards your limit and you may not write anything to disk. You must assume the input data is read-only when in memory so you can't reuse that to gain more working space.
**What do I have to implement?**
Your code should read in a file in the following format. It will have three lines. The first line is the true edit distance. The second is string 1 and the third is string 2. I will test it with the sample data at <https://bpaste.net/show/6905001d52e8> where the strings have length 10,000 but it shouldn't be specialised for this data. It should output the smallest edit distance it can find between the two strings.
You will also need to prove your edit distance actually comes from a valid set of edits. Your code should have a switch which turns it into a mode that may use more memory (as much as you like) and outputs the edit operations that give your edit distance.
**Score**
Your score will be the `(optimal edit distance/divided by the edit distance you find) * 100`. To start things off, notice that you can get a score by just counting the number of mismatches between the two strings.
You can use any language you like which is freely available and easy to install in Linux.
**Tie break**
In the case of a tie-break, I will run your code on my Linux machine and the fastest code wins.
[Answer]
# C++ 75.0
The program is designed to work with arbitrary text strings. They can be of any different lengths as long as neither exceeds 13824 characters. It uses 1,897 16-bit integers, which is equivalent to 949 32-bit integers. At first I was writing it in C, but then realized there was no function for reading a line.
The first command-line argument should be a filename. If a second argument exists, a summary of the edits is printed. The first line in the file is ignored while the second and third are the strings.
The algorithm is a doubly blocked version of the usual algorithm. It performs basically the same number of operations, but is of course much less accurate, since if a common subsequence gets split over the edge of a block, much of the potential savings are lost.

[Answer]
# C++, Score 92.35
Estimation Algorithm: The algorithm finds the first place the two string differ, and then tries all possible N operation permutations (insert, delete, replace - characters that match are skipped without consuming an operation). It scores each possible set of operations based on how much farther that set of operations successfully matches the two strings, plus how much it causes the string lengths to converge. After determining the highest-scoring set of N operations, the first operation in the set is applied, the next mismatch is found, and the process repeats until the end of the string is reached.
The program tries all values of N from 1-10 and selects the level that gave the best results. N=10 is generally the best now that the scoring method takes the string length into consideration. Higher values of N would probably be even better, but take exponentially more time.
Memory Usage: Since the program is purely iterative, it needs very little memory. Only 19 variables are used to track the program state. These are set by #defines to act as global variables.
Usage: The program is used the same as feersum's: the first parameter is assumed to be the file, and any additional parameters indicate that the edits should be shown. The program always prints the estimated edit distance, and the score.
Verification Output: The verification output it formatted in three rows:
```
11011111100101100111100110100 110 0 0000 0 01101
R I IR R D D D DDD D D
01 1111110010 0001110001101000110101000011101011010
```
The top row is the target string, the middle is the operations, and the bottom is the string being edited. Spaces in the operation line indicate that the characters match. 'R' indicates that the edit string has it's character in that position replaced with the target string's character. 'I' indicates that the edit string has the target string's character inserted at that position. 'D' indicates that the edit string has it's character in that position deleted. The edit and target strings have spaces inserted when the other has a character inserted or deleted so they line up.

# Python, 100
I did manage to calculate the edit distance perfectly in the allotted memory limit. Sadly, this entry violates two rules of the challenge, in letter if not in spirit.
First, I have not actually stored my data in 1000 32-bit ints. For 10000-character strings, my program creates two 10000-element arrays that will only contain +1, 0, or -1. At 1.585 bits per ternary number, it would be possible to pack those 20000 trits into 31700 bits, leaving 300 bits as more than enough for my 7 remaining 16-bit integers.
Second, I have not implemented the required mode for showing edits. I have, alternately, implemented a mode that prints out the full edit matrix. It is absolutely possible to calculate the edit path from that matrix, but I don't have time right now to implement it.

Can output around 15,000 numbers on my computer. Compile with `-lgmp -lgmpxx -O3`. Please make sure there aren't other programs active while running this, because I've noticed that on my computer it changed the number by almost 1,000, even with just Firefox.
## Explanation
This is an implemention of Bach's algorithm, although with a lot of optimizations.
The main function is `gen_factor`, which given \$n\$ returns \$q = p^\alpha\$ with probability \$\log(p) \#(\frac{n}{2q}, \frac nq] = \log(p) \lfloor\frac{\frac{N}{q} + 1}2\rfloor\$, where \$\#(a, b]\$ is the number of integers in that range.
We approximate that the floor isn't important, and then use rejection sampling to get back the appropriate distribution.
After multiplying by (the constant) \$\frac2N\$, we get \$\log(p)(\frac1q+\frac1N)\$. Now we group the terms by \$p\$, and for a given \$p\$ we have its probability being $$\log(p) \sum\_{\alpha=1}^{\lfloor \log\_p(N) \rfloor} (\frac1{p^\alpha}+\frac1N) = \log(p) (\frac1{p-1} - \frac1{p^{\lfloor \log\_p(N) \rfloor}} + \frac{\lfloor \log\_p(N) \rfloor}N) \leq \frac{\log(p)}{p-1} + \frac{\log(N)}{N}$$
We split the range to \$[2, 510510)\$, and \$[510510 \cdot2^i, 510510 \cdot2^{i+1})\$ for all \$i\$. For the first range, we precalculate stuff to get numbers with the correct probability. For each of the \$[510510 \cdot2^i, 510510 \cdot2^{i+1})\$ ranges we notice that the probability is decreasing, so we can just take the probability for \$p = 510510\cdot 2^i\$ and use rejection sampling. To lower the amount of numbers we have to generate, we require the numbers to be coprime to \$510510 = 2\cdot3\cdot5\cdot7\cdot11\cdot13\cdot17\$, so we need to multiply the probability by \$\frac{510510}{\varphi(510510)}\$ for the other segment.

# Context
After ["Computing a specific coefficient in a product of polynomials"](https://codegolf.stackexchange.com/q/198779/75323), asking you to compute a specific coefficient of polynomial multiplication, I wish to create a "mirror" challenge, asking you to compute a specific coefficient from polynomial division.
# Polynomial division
Let us establish an analogy with integer division. If you have two integers `a` and `b`, then there is a unique way of writing `a = qb + r`, with `q, r` integers and `0 <= r < b`.
Let `p(x), a(x)` be two polynomials. Then there is a unique way of writing `a(x) = q(x)p(x) + r(x)`, where `q(x), r(x)` are two polynomials and the degree of `r(x)` is strictly less than the degree of `p(x)`.
# Algorithm
Polynomial division can be performed through an iterative algorithm:
1. Initialize the quotient at `q(x) = 0`
2. While the degree of `a(x)` is at least as big as the degree of `p(x)`:
* let `n = degree(a) - degree(p)`, let `A` be the coefficient of the term of highest degree in `a(x)` and `P` be the coefficient of highest degree in `p(x)`.
* do `q(x) = q(x) + (A/P)x^n`
* update `a(x) = a(x) - p(x)(A/P)x^n`
3. `q(x)` is the quotient and what is left at `a(x)` is the remainder, which for our case will always be `0`.
# Task
Given two polynomials `a(x)`, `p(x)` such that there exists `q(x)` satisfying `a(x) = p(x)q(x)` (with all three polynomials having integer coefficients), find the coefficient of `q(x)` of degree `k`.
(Yes, we are assuming the remainder is `0`)
# Input
Two polynomials (with integer coefficients) and an integer.
Each input polynomial can be in any sensible format. A few suggestions come to mind:
* A string, like `"1 + 3x + 5x^2"`
* A list of coefficients where index encodes exponent, like `[1, 3, 5]`
* A list of `(coefficient, exponent)` pairs, like `[(1, 0), (3, 1), (5, 2)]`
An input format must be sensible AND completely unambiguous over the input space.
The integer `k` is a non-negative integer. You may take it in any of the usual ways. You can assume `k` is less than or equal to the differences of the degrees of `a(x)` and `p(x)`, i.e. `k <= deg(a) - deg(p)` and you can assume `deg(a) >= deg(p)`.
# Output
The **integer** corresponding to the coefficient of `x^k` in the polynomial `q(x)` that satisfies the equality `a(x) = q(x)p(x)`.
# Test cases
The input order for the test cases is `a(x)`, `p(x)`, integer `k`.

[Question]
[
Given a string that is potentially boxed in, toggle the box. This becomes clearer in the test cases and explanation.
# Input / Output
### Input Format
The input will be either a single string separated by CR, LF, or CRLF, or a list of strings. The input format is up to you to decide.
### Output Format
The output format must be in the same format as the input.
# Explanation + Example
Let's take a boxed string as an example:
```
+-------------+
|Hello, World!|
+-------------+
```
To toggle the box, we remove the first and last row and the first and last column. You may assume that there will be no trailing whitespace after the last line (with an optional trailing newline at the end of the last line), and no trailing whitespace on any line, not counting the newline of course.
This would become:
```
Hello, World!
```
# The Other Way
If the string is *not* in a box, add a box to it. This is fairly simple; prepend `+---...---+` on its own line with `k` dashes where `k` is the length of the longest line, and then for each line, pad it with trailing whitespace to match the length of the longest line and then prepend and append a pipe character (`"|"`). Finally, append a line containing the same `+---...---+` setup as the first line.
For example:
```
Hello, World!
```
becomes:
```
+-------------+
|Hello, World!|
+-------------+
```
You may assume that none of the lines in the input will have trailing whitespace.
Another example of a string that should have a box put around it:
```
Hello,
World!
```
becomes
```
+----------+
|Hello, |
| World!|
+----------+
```
An example of something that should still be boxed:
```
+--------+
| |
--------+
```
becomes:
```
+----------+
|+--------+|
|| ||
| --------+|
+----------+
```
# Rules + Specifications
* Standard Loopholes Apply
* No line of input will have any leading or trailing whitespace both overall and in each line, regardless of whether or not it has been boxed in
* Boxes will only have `+` as their corners and `|` for the vertical edges and `-` for the horizontal sides.
* A box must have its pluses in place to be considered a box; if it has height or width 2 (that is, no content), it should still be unboxed, which would result in a bunch of newlines, depending on the height of the box.
* If the input has a box but text outside of the box, the whole thing should be boxed.
* Your program must check the entire perimeter of the string. If a single character along the outside is not correct (either missing or a different character than what it should be), then it should be boxed, not unboxed.
* The unboxed string itself may contain `+ | -`. If the unboxed string itself has a box around it, return the string with the box; it should only be unboxed once.
# Edge Cases
### 1: Small boxes
Input:
```
++
++
```
Output is a empty or a newline
Input:
```
+----+
+----+
```
Output is empty or a newline
Input:
```
++
||
||
++
```
Output is 2 newlines or 3 newlines
### 2: Partial Box
Input:
```
+-------+
| Hello |
+ ------+
```
Output:
```
+---------+
|+-------+|
|| Hello ||
|+ ------+|
+---------+
```
### 3: Text outside of box
Input:
```
+-------+
a| Hello |
+-------+
```
Output:
```
+----------+
| +-------+|
|a| Hello ||
| +-------+|
+----------+
```

```
+m`^((.)*)(¶(?<-2>.)*(?(2)$|(.)))
$1$#4$* $3$#2$*
```
This stage is quite complicated in itself, so I'll break it down a bit. `+` means that the stage repeats until no more replacements can be found. `m`^` means that the stage matches at the start of any line. `((.)*)` then matches the whole line. Now `$1` is simply the matched line, but `$2` is a list of matches i.e. characters. `(¶` then matches the end of the line and therefore the start of the next line. `(?<-2>.)*` uses a .NET balancing group. The `<-2>` removes matches from `$2` as long as a character can be matched on the second line. At this point, one of three things can happen:
* There weren't enough characters on the second line. `$2` still has some matches left.
* The two lines were exactly the same length. `$2` has no matches left, and we are at the end of the line.
* The second line is longer, so there is at least one character left over.
`(?(2)$|(.)))` helps distinguish these using a condition. If `$2` still has some matches left, then we need this to be because the second line is too short, so we match the end of the line, but if `$2` has no matches left, then we want the second line to be longer, so we match a character (which goes into `$4` so that we know that the match happened). Otherwise the two lines are the same length and the match fails at this point (it might match again at a later line of course).
The replacement string is `$1$#4$* $3$#2$*`. The `$#4` evaluates to `1` if we matched an additional character on the second line, `0` if not. This means that `$#4$*` adds a space to the first line if the second line was longer. Similarly `$#2$*` adds spaces to the second line if the first line was longer. (In fact, it ends up adding exactly the right number of spaces. If we were only balancing two lines, a `+` could have been added to the fourth capture group to achieve this directly for the case of the longer second line too.)
The upshot of all this is that this stage pads out the input into a rectangle. We can now draw a box around it.
```
%`^|$
|
```
Place `|`s on each side.
```
^.(.*).
+$.1$*-+¶$&
```
Place `+-...-+` on the top.
```
.(.*).$
$&¶+$.1$*-+
```
And again on the bottom.
```
^(\+-*\+)¶(\|\+-*\+\|)¶(\|\|.*\|\|¶)*\2¶\1$
¶$&¶
```
See if we've created a double box. If so, extra blank lines are added at the top and bottom for the remaining stages to match to delete both boxes.
```
..(.*)..(?=(.|¶)*¶$)
$1
```
If there's a trailing blank line, remove two characters from the start and end of every line.
```
^¶-*¶-*¶|(\G|¶)-*¶-*¶$
```
If there's a leading blank line, delete it and the next two lines (which will be the `-`s remaining at the top of the box). If there's a trailing blank line, delete it and the previous two lines. The `(\G|¶)` deals with the case where there's only six lines (and therefore 5 `¶`s) because the box had no content.

I recently listed to the song [I'm a Textpert](https://m.youtube.com/watch?v=FWj42BxDXCU) about texting while driving and one particular line in the song inspired this challenge.

Now obviously, this would be an almost impossible thing to do in ones head and so you should help textperts world wide by coding a program to do the same thing.
Your job is to take the name of an image file with the dimensions `500x500` pixels and output the file as binary. You may also take an image as input, if you language supports it.
You may use image files with the extensions
* `.jpg`
* `.png`
* `.gif`
* `.bmp`
* `.svg`
Allow me to demonstrate how to convert an image into binary, for those who don't understand what I mean.
**Step 1**
Take the first pixel in the file and retrieve its RGB value as 3 decimal numbers: R, G and B. Let's assume, for example, that the first pixel is `255,0,0` (red).
**Step 2**
Convert each number into its 8-bit binary representation and concatenate into a single 24-bit number. For the example, this yields `111111110000000000000000`
**Step 3**
Add this 24-bit number to the final output. Therefore, the final output should be `6000000` digits long and should consist of entirely `1` and `0`

[Question]

Given two lists that contain no duplicate elements `a` and `b`, find the crossover between the two lists and output an ASCII-Art Venn Diagram. The Venn Diagram will use a squarified version of the traditional circles for simplicity.
# Example
**Given:**
```
a = [1, 11, 'Fox', 'Bear', 333, 'Bee']
b = ['1', 333, 'Bee', 'SchwiftyFive', 4]
```
**Output (Order is 100% arbitrary, as long as the Venn Diagram is correct):**
```
+-----+----+-------------+
|11 |333 |SchwiftyFive |
|Fox |Bee |4 |
|Bear |1 | |
+-----+----+-------------+
```
The program may either consider `'1' == 1` or `'1' != 1`, up to your implementation. You may also choose to just handle everything as strings, and only accept string input.
---
**Given:**
```
a=[]
b=[1,2,3]
```
**Output (Notice how the two empty parts still have the right-pad space):**
```
+-+-+--+
| | |1 |
| | |2 |
| | |3 |
+-+-+--+
```
---
**Given:**
```
a=[1]
b=[1]
```
**Output:**
```
+-+--+-+
| |1 | |
+-+--+-+
```
# Rules

`tinylisp` is, in its essence, a very stripped-down version of Lisp, as the name suggests. It was made by @DLosc for an "interpret this language" challenge, which can be found [here](https://codegolf.stackexchange.com/questions/62886/tiny-lisp-tiny-interpreter). It features a small amount of builtins, which can be used to create practically anything.
There is a repository for the "official" tinylisp interpreter/documentation [here](https://github.com/dloscutoff/Esolangs/tree/master/tinylisp), and it is available to try online [here](https://tio.run/nexus/tinylisp).
What tips do you have for golfing (creating the shortest program possible) in tinylisp? This question is looking for tips to golf specifically in tinylisp, not general tips that can be applied to any language.
[Answer]
# Abuse builtins for type-checking
The official way to check the type of a value is with the `type` builtin, which returns one of `Int`, `List`, `Name`, or `Builtin`. However, `(e(type x)(q Int))` is pretty verbose, and `(type? x Int)` with the library isn't too much shorter.
The good news here is that errors in tinylisp generally aren't fatal--they just print a warning to stderr and return `()` (nil). So under certain circumstances, we can use the one-letter builtins in unintended ways to perform ad-hoc type-checking. Supposing we have some value bound to the name `x`:
* `(a x 1)` - truthy for all integers except -1; falsey for -1; error for any other type
* `(s x 1)` - same, but replace -1 with 1
* `(a x 0)` - same, but with 0
* `(t x)` - truthy for lists with more than 1 element; falsey for nil and single-element lists; error for any other type
* `(h x)` - truthy for nonempty lists with a truthy first element; falsey for nil and lists with a falsey first element; error for any other type
* `(c()x)` - truthy for lists; error for any other type
* `(l()x)` - truthy for nonempty lists; falsey for nil; error for any other type
* `(l 0 x)` - truthy for positive integers; falsey for 0 and negative integers; error for any other type
* `(v x)` - truthy for nonzero integers; falsey for 0 and nil; error for any list that's not a valid s-expression (including any nonempty list of integers); result varies for valid s-exprs and names
Even the string builtins, though longer, could be useful under certain circumstances:
* `(string x)` - truthy for integers, builtins, names, and lists of integers (including nil); error for lists containing anything other than integers
* `(chars x)` - truthy for nonempty names; falsey for empty name; error for any other type
For example, here's a function that adds all the integers in a ragged list such as `(1 2 (3 4 (5) 6))`:
```
(d S(q((L)(i L(i(e(type L)(q Int))L(a(S(h L))(S(t L))))0
```
(We could write `(type? L Int)` for the type-check if we loaded the library, but that costs more bytes unless we need the library for something else.)
By the time execution reaches `(e(type L)(q Int))`, we know that `L` is either a nonempty list or a nonzero integer. We want a test that's truthy if `L` is an integer and falsey/error if `L` is a list. `(a L 0)` fits the bill:
```
(d S(q((L)(i L(i(a L 0)L(a(S(h L))(S(t L))))0
```
But in this case, so does `(v L)`. That's because:
* `v` on any integer returns the integer unchanged, and we know the integer won't be zero, so it's always truthy
* `v` on any list tries to evaluate the list as tinylisp code
* Nil evaluates to itself, but we know the list is nonempty
* A nonempty list evaluates as a function call, where the first element of the list is the function or macro. An integer isn't a valid function or macro; neither is nil; and a nonempty list will get evaluated as a function call, simply trying the same thing one layer down. Upshot: `v` will always error on a nonempty ragged list of integers.
Total savings: 13 bytes.
```
(d S(q((L)(i L(i(v L)L(a(S(h L))(S(t L))))0
```
[Answer]
# Use lambdas instead of full functions
To save a few bytes, you can make your answer a lambda instead of a full function:
```
Predecessor function:
(q (
(n)
(s n 1)))
Golfed:
(q((n)(s n 1)))
```
This is only useful if the function doesn't recurse.
[Answer]
# Take advantage of parenthesis autocompletion
The tinylisp parser will fill in missing close parens at the end of each line, provided that each of your top-level expressions is on a single line (which it should be anyway for code golf). So instead of this:
```
(load library)(d D(q((M)(i(h M)(c(h(h M))(D(map t(t M))))()))))
```
you can write this, for a savings of 5 bytes:
```
(load library
(d D(q((M)(i(h M)(c(h(h M))(D(map t(t M))))(
```
(Just make sure that your test code in the header or footer is formatted the same way, or you may get some puzzling error messages.)
[Answer]
# Use the library
Although tinylisp itself has a small set of builtins, it also comes with a standard library that adds a lot of functionality. You can access any function in the library by running `(load library)`.
The names of library functions/constants are not golfy like the builtins are, so some of them aren't worth it. For example, there's no need to load the library just to use `inc` or `dec`, since `(a 1 x)` is the same length as `(inc x)` and `(a(some-expr)1)` is shorter than `(inc(some-expr))`. For others, it depends on the use case: using `reverse` is probably shorter than reimplementing it yourself, but you may be able to restructure your code to avoid using it at all. Others, like `*`, are indispensable (multiplication isn't built in, and reimplementing it would be prohibitively long).
One drawback: there's not really any documentation besides just [reading the code](https://github.com/dloscutoff/Esolangs/tree/master/tinylisp/lib).
[Answer]
# Try switching the order of expressions
When you have multiple atoms (names/integers) next to each other, they have to be separated by whitespace. In some cases, you can rearrange the expression to eliminate the whitespace. A common example is with addition:
```
(a 1(subexpression))
(a(subexpression)1)
```
A less obvious case is when you have a function with multiple arguments. Consider a function `F` with arguments `(A B)`. If you're calling the function like this:
```
(F A(s B 1))
```
then you may be able to save a byte by taking the arguments as `(B A)` instead:
```
(F(s B 1)A)
```
(These particular examples only work if they're not at the end of a line; in that case, parenthesis autocompletion would make both options the same length. But there are instances where switching the order helps even at the end of a line.)
Reordering can be especially helpful with conditionals. Frequently, you will have a recursive function with a body structured like this:
```
(i(condition)(recursive call)(base case))
```
In some instances, you can save bytes by inverting the condition and reversing the order of the truthy and falsey branches:
```
(i(inv-condition)(base case)(recursive call))
```
For example, here's a function `F` that returns [the length of a number's Collatz orbit](https://codegolf.stackexchange.com/q/12177/16766):
```
(load library
(d F(q((N)(i(l 1 N)(a(F(i(odd? N)(a(* 3 N)1)(/ N 2)))1)0
```
If we change the condition `(l 1 N)` (truthy if N is greater than 1, falsey if N is 1 or less) to `(l N 2)` (truthy if N is less than 2, falsey if N is 2 or greater), we can switch the truthy and falsey branches and save a byte thanks to parenthesis autocompletion:
```
(d F(q((N)(i(l N 2)0(a(F(i(odd? N)(a(* 3 N)1)(/ N 2)))1
```
In this particular case, we can then save more bytes by rewriting `(a(...)1` to `(a 1(...`:
```
(d F(q((N)(i(l N 2)0(a 1(F(i(odd? N)(a(* 3 N)1)(/ N 2
```

Tamagotchi and Giga Pets were small electronic devices which simulated a little virtual pet. This pet had several stats, like health, hunger, etc.
I recently wrote this example:
```
import msvcrt,os,sys;d=m=100;h=s=t=p=0;f=10
while 1:
os.system('cls'if os.name=='nt'else'clear');print("health:",d,"\nhunger:",h,"\nsleep:",s,"\nfood:",f,"\npotions:",p,"\nmoney:",m);t+=1
if msvcrt.kbhit():
k=ord(msvcrt.getch())
if k==102 and h>8 and f:f-=1;h-=9
if k==115:s=0
if k==112 and p:p-=1;d+=9
if k==98 and m>8:m-=9;p+=1
if k==116 and m>8:m-=9;f+=1
if t>99:
t=0;h+=1;s+=1
if s>80:s=0;h+=9
if h>80:d-=1
if d<1:sys.exit(0)
if d>79:m+=1
```
This is a bare-bones virtual pet in 467 bytes! I then wondered how well the **code golf pros** could do, so now, the challenge.
# The Challenge
Make a program that tracks 6 stats of a virtual pet, and updates them over time and in response to user input. The stats are: health and money (starting at 100), food (starting at 10), and hunger, sleep, and potions (starting at 0).
The program should update the values in response to the following events:
* While the program is receiving no input, it should perform updates at regular intervals (the interval between updates should not be shorter than half a second nor longer than one second). Each update does the following:
+ Hunger and Sleep each increase by 1.
+ If Hunger is 80 or above, Health decreases by 1.
+ If Sleep is 80 or above, it is reset to 0, and Hunger increases by an additional 9.
+ If Health is 80 or above, Money increases by 1.
+ If Health is 0, the program exits.
* The program must also respond immediately upon the following keypresses by the user (this means that you will need to use a language feature or library that can detect a key being pressed and respond to it immediately, rather than just reading from standard input), performing the following actions:
+ `f`: If Hunger is greater than 8 and Food is nonzero, then Food is decreased by 1 and Hunger is decreased by 9.
+ `s`: Sleep is reset to 0.
+ `p`: If Potions is greater than zero, Potions is decreased by 1 and Health is increased by 9.
+ `b`: If Money is greater than 8, then Money is decreased by 9 and Potions are increased by 1.
+ `t`: If Money is greater than 8, then Money is decreased by 9, and Food is increased by by 1.
Whenever the values of the stats change, they must be displayed on screen in the form `Stat: *value*`. All six stats must be displayed whenever any of them changes; and the stats within a display must be separated either by commas or by newlines.
This challenge follows normal [code-golf](/questions/tagged/code-golf "show questions tagged 'code-golf'") rules: the shortest program complying with the specification above wins. (Note that as usual, if the language is newer than the competition, the submission must be marked as non-competing.)

I appreciate the need for raw input and asynchronous updates in the problem spec. Even though that required some overhead from the ncurses setup and signal handlers, it's nice to have the occasional challenge that (hopefully) won't be automatically won by one of the dedicated golfing languages.
You didn't specify exactly how game over is indicated, so this one perishes with the traditional Tamagotchi death cry of "Floating point exception (core dumped)".

Requires a unix-ish OS for the non-blocking STDIN. Oddly, using switch/case versus cascading if/else produced shorter source code, but the subsequent compressed version was longer.

The line breaks are important because they are newline characters in the string so I could use `Row` instead of `Column`. If you evaluate this in a Mathematica notebook you should see something like this:
[](https://i.stack.imgur.com/3S75t.png)
You have to click in the input field and quickly (less than a second) type your character before `Dynamic` causes the input field to update. This headache could be avoided entirely if the `EventHandler` was in its own cell rather than being an element of `Row`, but that would require saving the program as a .nb file which would greatly increase the byte count.

Made all the atoms loose variables instead of being inside a state object. That alone got rid of a lot of code. I also created the shortcut functions `a!` and `s!` to add and subtract from the `atoms` easier (basically acting as `+=` and `-=`, since Clojure doesn't have those operators).
I realized that I could probably do away with `atom`s if I manage to integrate key input into a `loop`. I'll have to see.

Ohdeargod. Definitely room for improvement here. This kind of problem is easiest to do with side effects, and Clojure is functional, so I'm trying to abuse `atom`s to lessen the amount of code needed. Unfortunately, I didn't go in with a plan, so it's kind of haphazard right now. I've already gotten a few ideas to shrink I though.
It's a full program. It can be run by running `-main`.

In the examples below, `A` and `B` will be 2-by-2 matrices, and the matrices are one-indexed.
A [Kronecker *product*](http://mathworld.wolfram.com/KroneckerProduct.html) has the following properties:
```
A⊗B = A(1,1)*B A(1,2)*B
A(2,1)*B A(2,2)*B
= A(1,1)*B(1,1) A(1,1)*B(1,2) A(1,2)*B(1,1) A(1,2)*B(1,2)
A(1,1)*B(2,1) A(1,1)*B(2,2) A(1,2)*B(2,1) A(1,2)*B(2,2)
A(2,1)*B(1,1) A(2,1)*B(1,2) A(2,2)*B(1,1) A(2,2)*B(1,2)
A(2,2)*B(2,1) A(2,2)*B(1,2) A(2,2)*B(2,1) A(2,2)*B(2,2)
```
A [Kronecker sum](http://mathworld.wolfram.com/KroneckerSum.html) has the following properties:
```
A⊕B = A⊗Ib + Ia⊗B
```
`Ia` and `Ib` are the [identity matrices](http://mathworld.wolfram.com/IdentityMatrix.html) with the dimensions of `A` and `B` respectively. `A` and `B` are square matrices. Note that `A` and `B` can be of different sizes.
```
A⊕B = A(1,1)+B(1,1) B(1,2) A(1,2) 0
B(2,1) A(1,1)+B(2,2) 0 A(1,2)
A(2,1) 0 A(2,2)+B(1,1) B(1,2)
0 A(2,1) B(2,1) A(2,2)+B(2,2)
```
**Given two square matrices, `A` and `B`, calculate the Kronecker sum of the two matrices.**
* The size of the matrices will be at least `2-by-2`. The maximum size will be whatever your computer / language can handle by default, but minimum `5-by-5` input (5 MB output).
* All input values will be non-negative integers
* Builtin functions that calculate the Kronecker sum or Kronecker products are not allowed
* In general: Standard rules regarding I/O format, program & functions, loopholes etc.

### Explanation
This code is an exercise in compound (or infix) operators. These are generally useful for array manipulation, but this challenge exacerbated the need for them. Here is a quick overview:
* `f` expects a list and something else on the stack and maps the following *binary* operator over the list, passing in the other element as the second argument. E.g. `[1 2 3] 2 f*` and `2 [1 2 3] f*` both give `[2 4 6]`. If both elements are lists, the first one is mapped over and the second one is used to curry the binary operator.
* `:` has two uses: if the operator following it is unary, this is a simple map. E.g. `[1 0 -1 4 -3] :z` is `[1 0 1 4 3]`, where `z` gets the modulus of a number. If the operator following it is binary, this will *fold* the operator instead. E.g. `[1 2 3 4] :+` is `10`.
* `.` vectorises a binary operator. It expects two lists as arguments and applies the operator to corresponding pairs. E.g. `[1 2 3] [5 7 11] .*` gives `[5 14 33]`.
Note that `:` itself is always a unary operator, whereas `f` and `.` themselves are always binary operators. These can be arbitrarily nested (provided they have the right arities). And that's what we'll do...
```
9Yb e# Push the binary representation of 9, i.e. [1 0 0 1].
2/ e# Split into pairs, i.e. [[1 0] [0 1]]. We'll use these to indicate
e# which of the two inputs we turn into an identity matrix.
q~ e# Read and evaluate input, [A B].
f{ e# This block is mapped over the [[1 0] [0 1]] list, also pushing
e# [A B] onto the stack for each iteration.
.{ e# The stack has either [1 0] [A B] or [0 1] [A B]. We apply this
e# block to corresponding pairs, e.g. 1 A and 0 B.
_, e# Duplicate the matrix and get its length/height N.
,_ e# Turn into a range [0 1 ... N-1] and duplicate it.
ff= e# Double f on two lists is an interesting idiom to compute an
e# outer product: the first f means that we map over the first list
e# with the second list as an additional parameter. That means for
e# the remaining operator the two arguments are a single integer
e# and a list. The second f then maps over the second list, passing
e# in the the number from the outer map as the first parameter.
e# That means the operator following ff is applied to every possible
e# pair of values in the two lists, neatly laid out in a 2D list.
e# The operator we're applying is an equality check, which is 1
e# only along the diagonal and 0 everywhere else. That is, we've
e# created an NxN identity matrix.
? e# Depending on whether the integer we've got along with the matrix
e# is 0 or 1, either pick the original matrix or the identity.
}
e# At this point, the stack contains either [A Ib] or [Ia B].
e# Note that A, B, Ia and Ib are all 2D matrices.
e# We now want to compute the Kronecker product of this pair.
:ffff* e# The ffff* is the important step for the Kronecker product (but
e# not the whole story). It's an operator which takes two matrices
e# and replaces each cell of the first matrix with the second matrix
e# multiplied by that cell (so yeah, we'll end up with a 4D list of
e# matrices nested inside a matrix).
e# The leading : is a fold operation, but it's a bit of a degenerate
e# fold operation that is only used to apply the following binary operator
e# to the two elements of a list.
e# Now the ffff* works essentially the same as the ff= above, but
e# we have to deal with two more dimensions now. The first ff maps
e# over the cells of the first matrix, passing in the second matrix
e# as an additional argument. The second ff then maps over the second
e# matrix, passing in the cell from the outer map. We multiply them
e# with *.
e# Just to recap, we've essentially got the Kronecker product on the
e# stack now, but it's still a 4D list not a 2D list.
e# The four dimensions are:
e# 1. Columns of the outer matrix.
e# 2. Rows of the outer matrix.

### How it works
* For matrices **A** and **B**, `map(a->a*B,A')` computes the Kronecker product **A⊗B**.
The result is a vector of matrix blocks with the dimensions of **B**.
We have to transpose **A** (with `'`) since matrices are stored in column-major order.
* Since bitwise NOT with two's complement satisfies the identity **~n = -(n + 1)** for all integers **n**, we have that **-~-n = -(~(-n)) = --((-n) + 1) = 1 - n**, so **-~-0 = 1** and **-~-1 = 0**.
This way the anonymous function `i->map(a->a*B^i,A'^-~-i)` applies the above map to **B⁰** (the identity matrix with **B**'s dimensions) and **A¹ = A** when **i = 0**, and to **B¹** and **A⁰** when **i = 1**.
* `sum(i->map(a->a*B^i,A'^-~-i),0:1)` sums over **{0,1}** with the above anonymous function, computing the Kronecker sum **A⊕B** as **A¹⊗B⁰ + A⁰⊗B¹**.
The result is a vector of matrix blocks with the dimensions of **B**.
* `sum(A^0)` computes the sum of all entries of the identity matrix of **A**'s dimensions. For an **n×n** matrix **A**, this yields **n**.
* Finally, `hvcat(sum(A^0),sum(i->map(a->a*B^i,A'^-~-i),0:1)...)` concatenates the matrix blocks that form **A⊕B**.
With first argument **n**, `hvcat` concatenates **n** matrix blocks horizontally, and the resulting (larger) blocks vertically.

[Question]
[
Given a string of letters and a set of words, output an ordering of the words so
that they can be found in the string by dropping letters that are not needed.
Words may occur more than once in the word set. The input string and all words
will consist of 1 to 1000 lower case letters each. The letters to be dropped may occur inside words or between words.
Your program or function can accept the letter string and words as lists, a string, or from STDIN, and must output all words in a correct order as a list
or string output. If there is more than one correct solution, only output one of
them. If there is no possible correct solution, output an empty list or an empty
string.
Examples:
```
dogcatfrog cat frog dog
-> dog cat frog
xxcatfixsxhingonxgrapexxxfishingcxat cat grape catfish fishing
-> catfish grape fishing cat
dababbabadbaccbcbaaacdacdbdd aa bb cc dd ba ba ba ab ac da db dc
-> da ab ba ba ba cc bb aa ac dc db dd
flea antelope
->
(no solution)
```
This is code golf. Lowest number of bytes wins.

This program is very much brute force. It first constructs every subset of the input, then every partition of the subsets, then checks for the first one which is a reordering of the word list. No possibilities is handled via erroring with no output to stdout, which is allowed by meta consensus. The error can be removed for 2 extra bytes.
Note that for many of the given test cases, the program will not complete in a reasonable period of time.

```
Accepts a string and an array of words and returns an array of words or `undefined` on failure. Add 2 bytes if it must return the empty string on failure (`?q:```), in which case this alternative version is only 120 bytes and returns the empty string on failure, and can even save 2 bytes if it's allowed to return 0 on failure:
```
(s,a,t=``,...r)=>a[0]?a.reduce((q,w,i)=>q||(b=[...a],b.splice(i,1),f(s,b,w+t,w,...r)),0):~s.search([...t].join`.*`)?r:``

# Groovy (44 Bytes)
I can't believe nobody else used regexes for this...
```
{a,b->a.findAll(/${b.join('|')}/).join(" ")}
```
## Explanation
`/${b.join('|')}/` - Create a regex to find any of the words in a string.
`.findAll(...)` - Find and collect all occurrences in the string into an array.
`.join(" ")` - Join the array together with spaces.
Basically, if there aren't any occurrences, the array is empty and returns an empty string implicitly. If it does find occurrences, it returns an array object with the occurrences then flattens it into a string.

# Introduction
[Doppelkopf](https://en.wikipedia.org/wiki/Doppelkopf) is a traditional German card game for 4 players. The deck consists of 48 cards (9, 10, Jack, Queen, King, Ace of each suit while every card is in the game twice), so each player gets 12 at the start of a round.
There are always 2 teams which are determined by the distribution of the Queens of Clubs. The 2 players who are holding the Queens form a team and play against the other 2 players. The team with the Queens of Clubs are called the "Re"-team, the one without is the "Contra"-team.
At the start of the round noone knows who is on which team. The team distribution will be revealed in the progress of the round, which adds a lot of strategy to the game.
The game consists of 12 tricks. The players who wins a trick gets all the 4 cards in it. Every card has a certain value (King counts 4, Ace counts 11 for example), all cards together sum up to 240 points which is the highest possible result.
At the end of a round the points are counted and the team with the highest amount of points wins the round. Then then next round starts...
# The Challenge
Every round has a certain score which is determined by the amount of points the winning team got and potential announcements. You will have to write a program that takes the point distribution and potential announcements (see explanation below) as input and outputs the score of the round and the winner.
# The score calculation
As mentioned there is a Re- and a Contra-team. Also there is a maximum of 240 points possible in one round. The Re-team has to get 121 points to win, while the Contra-team only needs 120. There is also the possibility to announce "Re" or "Contra" at the start of the round if you think that you will win the game. By doing this you are raising the score.
Here are the scoring rules:
* +1 for winning the game
* +1 if the losing team has **less** than 90 points ("Keine 90")
* +1 if the losing team has **less** than 60 points ("Keine 60")
* +1 if the losing team has **less** than 30 points ("Keine 30")
* +1 if the losing team has 0 points ("Schwarz")
* +2 for an announcement of Contra
* +2 for an announcement of Re
* +1 if the Contra team won ("Gegen die Alten")
**Note:** Re/Contra-Announcements always apply, regardless of the winner. See examples in the testcases below.
# Input and Output
The input to the program will be the score of the Re-team and potential announcements of Re or Contra. Since there are always 240 points in the game you can easly calculate the score of the Contra-team.
The input will be a single string which has the score of the Re-team first, followed by the potential announcements, while "R" is for Re and "C" is for Contra. If both got announced, Re will always come first.
Output will be the score of the game followed by the winning team ("C" for Contra, "R" for Re)
# Rules
* Your submission can be a full program or a function. If you choose the latter include an example on how to invoke it.
* Input can be provided by function- or command line arguments or user input.
* Output can be provided as return value or printed to the screen.
* [Standard loopholes](http://meta.codegolf.stackexchange.com/questions/1061/loopholes-that-are-forbidden-by-default) apply.
* Lowest Byte-Count wins!
# Testcases
```
Input -> Output (Explanation)
145R -> 3R (Re won, +1 for winning, +2 for Re-Announcement)
120 -> 2C (Contra won, +1 for winning, +1 for winning as Contra)
80C -> 5C (Contra won, +1 for winning, +1 for no 90, +1 for winning as Contra, +2 for Contra-Announcement)
240R -> 7R (Re won, +1 for winning, +1 for no 90, +1 for no 60, +1 for no 30, +1 for no points for the losing team, +2 for Re-announcedment)
90 -> 2C (Contra won, +1 for winning, +1 for winning as Contra)
110RC -> 6C (Contra won, +1 for winning, +1 for winning as Contra, +2 for Re-Announcement, +2 for Contra-Announcement)
110R -> 4C (Contra won, +1 for winning, +1 for winnins as Contra, +2 for Re-Announcement)
184C -> 5R (Re won, +1 for winning, +1 for no 90, +1 for no 60, +2 for Contra-Announcement)

Ahh, it's been way too long since I used Labyrinth. It's always quite a joy to golf it. :)
### Explanation
*This is a bit outdated now. The overall structure of the program is still the same, but a few details have changed. I'll update this later. This is the previous solution, for reference:*
```

`

```
Let's break down the score a bit:
* If we count the characters after the number in the input, let's call it `M`, then there will be `2M+1` points in the final score, for winning, Re, and Contra.
* If the score is 120 or less, Contra wins and the score is incremented by `1`.
* Looking at the losing score, we can (integer) divide it by 30 to determine the additional points. That has three problems though: 1. the value increases in the wrong direction, so we need to subtract it from the score (and add 3 to it to correct for that). 2. This gives an additional point for a result of exactly 120, which we need get rid of. 3. It doesn't handle a result of 0 (for the losing side) yet, but we can include it by turning 0 into -1 (since Labyrinth's integer division rounds towards `-∞`).
That's pretty much how the code works. Sp3000 posted a good primer for Labyrinth today, so I decided to steal it. :)
* Labyrinth is stack-based and two-dimensional, with execution starting at the first recognised character. There are two stacks, a main stack and an auxiliary stack, but most operators only work on the main stack. Both stacks are bottomless, filled with zeroes.
* At every branch of the labyrinth, the top of the stack is checked to determine where to go next. Negative is turn left, zero is straight ahead and positive is turn right.
* Digits don't push themselves (as they do in Befunge, ><> or Prelude) - instead they "append themselves" to the top of stack, by multiplying the top by 10 and adding themselves.
So execution starts on the `(` in the first row, with the instruction pointer (IP) going right. `(` just turns the top of the main stack into `-1` and `}` shifts it off to the auxiliary stack, where we can forget about it. The program really starts with the `?` which reads the integer from STDIN. The IP then hits a dead end and turns around.
`}` shifts the input to the auxiliary stack and `(` decrements another zero to `-1`. This will be the final score. We now enter a very tight clockwise loop:
```
;)
,)
```
The `))` increments the score by two (so the first time we go through the loop, the score becomes `1`, the score for winning). Then `,` reads a character. As long as that's not EOF, the loop continues. `;` discards the character, because we don't care if it was `R` or `C` and `))` adds two to the score again. This will repeat 0, 1 or 2 times depending on the input.
We leave the loop, when we've hit EOF, the top of the stack will be `-1`. We then run this linear part:
```
`20{:}-
```
The ``` is unary negation, so we get `1`, then `20` turns it into a `120`. `{:}` gets a copy of the input integer from the auxiliary stack and `-` computes the difference with `120`. We can use the sign of this result to determine who won.
1. If the result is negative, Re won and we take the northern path, executing:
```
;}82{_240{-#;
```
`;` discards this result, `}` shifts the score away, `82` puts itself (character code of `R`) at the bottom of the main stack, `{` gets the score back on top, `_240{-` subtracts the integer input from 240 so we can work with Contra's (the losing side's) points.
The `#;` is just to ensure that we have a non-zero value on the stack so we can join up both paths reliably.
2. If the result is positive, Contra won and we take the southern path, executing:
```
;#"-))}67{{#;
```
The `#` pushes the stack depth which is `1`. This gets subtracted from the score before we add `2` with `))`. `67` puts itself (character code of `C`) at the bottom of the main stack. `{{` gets the other values back.
3. If the result is zero, Contra still won. However, that's the 120/120 case for which we need add an extra point to the final score (see above). That's why this path doesn't push a 1 with `#`, but instead just leaves the zero such that the `-` simply removes that zero from the stack.
The stacks are now joined back together and we've accounted for everything except the part where we divide by 30. But first, we need to turn a zero-score into -1. That's what this little detour does:
```
("
`"~
```
The ``` doesn't affect a zero, `"` is a no-op and `~` is bitwise negation. The bitwise NOT of `0` is `-1` as required. If the score was positive instead, then ``` makes it negative, `(` decrements it by `1` and `~` undoes both of those operations in one go.
```
#0/#--!.@
```
The stack depth is now 3 (the winning side's character, the total score so far, and the losing side's points), so `#` pushes `3`. `0` turns it into a `30`, `/` does the division. `#` pushes another `3` which is subtracted and that result is in turn subtracted from the final score. `!` prints it as an integer, `.` prints the winning side as a character and `@` terminates the program.

`p.length*2` overestimates the score by 1 if Re wins so I have to subtract `r` again. `!(n%120)+3-((r?240-n:n)/30|0)` is what I came up with to encapsulate the rules for scoring "Keine"; I so wish the boundaries had been 31, 61 and 91 as that would have made the formula `4-((r?269-n:29+n)/30|0)`.

[Question]
[
Two rows of a matrix are *orthogonal* if their inner product equals zero. Call a matrix with all rows pairwise orthogonal an *orthogonal matrix*. A [circulant matrix](https://en.wikipedia.org/wiki/Circulant_matrix) is one where each row vector is rotated one element to the right relative to the preceding row vector. We will only be interested in matrices where the entries are either `-1` or `1`.
**Task**
Write code to count as many different `n/2` by `n` orthogonal, circulant matrices as possible in 2 minutes (for even `n`).
**Input**
The code has no input. It can try any even values of `n` it likes. For example, the code could try all `n` that are multiplies of `4` starting from the smallest and also try `n = 2`.
**Output**
The number of orthogonal circulant matrices you have found. There should also be a simple switch in your code to enable it to output the matrices themselves.
**Score**
The number of circulant matrices you have found.
**Hints**
Orthogonal `n/2` by `n` circulant matrices only exist when `n` is a multiple of `4` or `n` is less than `4`.
An example orthogonal circulant matrix is:
```
-1 1 -1 -1
-1 -1 1 -1
```
**Tips for a naive approach**
The most naive approach is just to iterate over all possible matrices. This can be sped up using the following two observations.
* To test orthogonality of a circulant matrix we need only compare each row to the first one. This is implemented in the sample code.
* We can iterate over [Lyndon words](https://en.wikipedia.org/wiki/Lyndon_word) and then if we find an orthogonal matrix multiply by the number of possible rotations. This is idea as yet untested so may be buggy.
**Sample code**
This is a very simple and naive python answer. I ran it using `timeout 120`.
```
import itertools
def check_orthogonal(row):
for i in xrange(1,int(n/2)):
if (sum(row[j]*row[(j+i) % n] for j in xrange(n)) != 0):
return False
return True
counter = 0
for n in xrange(4,33,4):
for row in itertools.product([-1,1],repeat = n):
if check_orthogonal(row):
counter +=1
print "Counter is ", counter, ". n = ", n
```
**Correctness tests**
For `n = 4,8,12,16,20,24,28`, the number of distinct matrices you should get is `12,40,144,128,80,192,560`, respectively.
**Levels of awesomeness**
Judging by the sample code, I hereby present two levels of awesomeness that any answer can aspire to achieve.
* Silver level awesomeness is achieved by getting a score or *1156*.
* Gold level of awesomeness is to get higher than that.
**Languages and libraries**
You can use any language or library you like (that wasn't designed for this challenge). However, for the purposes of scoring I will run your code on my machine so please provide clear instructions for how to run it on Ubuntu.
**My Machine** The timings will be run on my machine. This is a standard Ubuntu install on an 8GB AMD FX-8350 Eight-Core Processor. This also means I need to be able to run your code.

# OCaml, 1588 (n = 36)
This solution uses the usual bit pattern approach to represent vectors of -1s and 1s. The scalar product is as usual calculated by taking the xor of two bit vectors and subtracting n/2. Vectors are orthogonal iff their xor has exactly n/2 bits set.
Lyndon words are not per se useful as a normalized representation for this, as they exclude any pattern that is a rotation of itself. They are also relatively expensive to compute. Therefore, this code uses a somewhat simpler normal form, which requires that the longest consecutive sequence of zeroes after rotation (or one of them, if there are multiples) must occupy the most significant bits. It follows that the least significant bit is always 1.
Observe also that any candidate vector must have at least n/4 ones (and at most 3n/4). We therefore only consider vectors with n/4 ... n/2 bits set, since we can derive others via complement and rotation (in practice, all such vectors seem to have between n/2-2 and n/2+2 ones, but that seems to also be difficult to prove).
We build these normal forms from the least significant bit up, observing the constraint that any remaining runs of zeroes (called "gaps" in the code) must follow our normal form requirement. In particular, as long as at least one more 1-bit has to be placed, there must be room for the current gap and another than that is at least as big as the current gap or any other gap observed so far.
We also observe that the list of results is small. Therefore, we do not try to avoid duplicates during the discovery process, but simply record the results in per-worker sets and calculate the union of these sets at the end.
It is worth noting that the runtime cost of the algorithm still grows exponentially and at a rate that is comparable to that of the brute-force version; what this buys us is essentially a reduction by a constant factor, and comes at the cost of an algorithm that is more difficult to parallelize than the brute-force version.
Output for n up to 40:
```
4: 12
8: 40
12: 144
16: 128
20: 80
24: 192
28: 560
32: 0
36: 432
40: 640
```
The program is written in OCaml, to be compiled with:
```
ocamlopt -inline 100 -nodynlink -o orthcirc unix.cmxa bigarray.cmxa orthcirc.ml
```
Run `./orthcirc -help` to see what options the program supports.
On architectures that support it, `-fno-PIC` may offer some small additional performance gain.
This is written for OCaml 4.02.3, but may also work with older versions (as long as they aren't too old).
---
UPDATE: This new version offers better parallelization. Note that it uses `p * (n/4 + 1)` worker threads per instance of the problem, and some of them will still run considerably shorter than others. The value of `p` must be a power of 2. The speedup on 4-8 cores is minimal (perhaps around 10%), but it scales better to a large number of cores for large `n`.

## Java, 1156 matrices
This uses fairly naive bitmasking, and takes under 15 seconds for n=28 on my machine.
Circulant matrices are determined by their first rows. Therefore, I represent the first rows of the matrices as bit vectors: 1 and 0 represent -1 and 1. Two rows are orthogonal when the number of set bits when they're xor'd together is n/2.
```
import java.util.Arrays;
class Main {
static void dispmatrix(long y,int N)
{
int[][] arr = new int[N/2][N];
for(int row=0; row < N/2; row++)
{
for(int col=0; col < N; col++)
{
arr[row][col] = (int) ((y >>> (N+row-col)) & 1L);
}
}
System.out.println(Arrays.deepToString(arr));
}
public static void main(String[] args) {
int count = 0;
boolean good;
boolean display = false;
long y;
for(int N=4; N <= 28 ;N += 4)
{
long mask = (1L << N) - 1;
for(long x=0; x < (1L<<N); x++)
{
good = true;
y = x + (x << N);
for(int row = 1; row < N/2; row++)
{
good &= N/2 == Long.bitCount((y ^ (y >>> row)) & mask);
}
if(good)
{
if(display) dispmatrix(y,N);
count++;
}
}
System.out.println(count);
}
}
}
```
I can't get Eclipse to work right now, so this was tested on repl.it.
Here are the number of first rows that are orthogonal to the first r rows afterwards for n=28:
```
[268435456, 80233200, 23557248, 7060320, 2083424, 640304, 177408, 53088, 14896, 4144, 2128, 1008, 1008, 560]
```
Optimizations:
* Since orthogonality doesn't change with a cyclic rotation of both rows, we just need to check that the first row is orthogonal to the rest.
* Rather than manually do an N-bit cyclic shift N/2 times, I store the bits to be shifted in at the top of the `long`, and then use a single `and` with the lower N bits to extract the needed ones.
Possible further optimizations:
* Generate Lyndon words. According to my calculations this only makes sense if Lyndon words can be generated in less than ~1000 cycles each.
* If Lyndon words take too long, we can still only check the bit vectors that start in `00`, and use their rotations (and rotations of the NOT) when we find an orthogonal matrix. We can do this because `0101...01` and `1010...10` are not possible first rows, and all the others contain either a `00` or a `11`.
* Branch maybe halfway through when the matrix is probably orthogonal. I don't know how much branching will cost, though, so I'll need to test.
* If the above works, start with a row other than row 1?
* Maybe there's some mathematical way to eliminate some possibilities. I don't know what that would be.
* Write in C++, of course.

[Question]
[
In this challenge, you need to parse morgue files from the roguelike game [Dungeon Crawl Stone Soup](http://crawl.develz.org) and output it to STDOUT.
## What are these morgue files??
When you die, a text file is generated with that character's data inside. You can see what equipment the character had, what happened during the last few turns, and how many monsters he has killed.
You can find a example morgue file [here](http://crawl.berotato.org/crawl/morgue/Ryuzilla/morgue-Ryuzilla-20150317-113750.txt)
## The challenge
Your job is to make a program that takes one of those files from STDIN, parses it, and outputs the data to STDOUT.
To make this challenge a bit easier, you only have to parse the first block of text. (up until `The game lasted <time> (<turns> turns).`
You need to parse and output the following information:
* The version number.
* The score.
* The character name, title, race and class.
* The character level.
* The cause of death/victory.
* The amount of turns the run lasted.
Example:
```
Dungeon Crawl Stone Soup version <version number> character file.
<score> <name> the <title> (level <level>, 224/224 HPs)
Began as a <race> <class> on Mar 16, 2015.
Was the Champion of the Shining One.
<cause of death/victory>
The game lasted 16:11:01 (<turns> turns).
```

For now, this is a test-driven regular expression.
It simply replaces the unwanted info and keeps the important stuff.
It creates an anonymous function that simply returns the wanted text.
```

[Question]
[
The [*Ship of Theseus*](http://en.wikipedia.org/wiki/Ship_of_Theseus) is an old question that goes something like:
>
> If a ship has had all of its original parts replaced, is it still the same ship?
>
>
>
For this golf, we're going to slowly replace "parts" on a "ship", and see how long it takes to get a whole new ship.
### Task
A ship is comprised of at least two parts. The parts are given as an array of positive (non-zero) integers, representing the part's condition.
On each cycle, [randomly choose](http://meta.codegolf.stackexchange.com/a/1325/14215) one part from the list in a uniform fashion. That part's condition will be reduced by one. When a part's condition reaches zero, it is replaced by a new part. The new part starts with the same condition value as the original did.
On the first cycle where all parts have been replaced (at least) once, stop and output the number of cycles it took.
For example (assume I'm choosing parts randomly here):
```
2 2 3 <- starting part conditions (input)
2 1 3 <- second part reduced
2 1 2 ...
2 1 1
2 2 1 <- second part reduced to zero, replaced
1 2 1
1 2 3 <- third part replaced
1 1 3
2 1 3 <- first part replaced
```
Output for this example would be `8`, since it took eight cycles for all parts to be replaced. Exact output should differ for each run.
### I/O
The only input is the list/array of integers for part condition. The only output is a number of cycles. You can take/give these values in any of the usual ways: STDIO, function arguments/returns, etc.
### Test Cases
Since output is not fixed, you could use whatever you want to test, but here's a couple for standardization purposes:
```
1 2 3 4
617 734 248 546 780 809 917 168 130 418
19384 74801 37917 81706 67361 50163 22708 78574 39406 4051 78099 7260 2241 45333 92463 45166 68932 54318 17365 36432 71329 4258 22026 23615 44939 74894 19257 49875 39764 62550 23750 4731 54121 8386 45639 54604 77456 58661 34476 49875 35689 5311 19954 80976 9299 59229 95748 42368 13721 49790

[Online demo](http://golfscript.apphb.com/?c=OyJbMiAyIDNdIgoKfnskKSp9ey4scmFuZHsoK30qKCgrfS8sCg%3D%3D)
CJam (same idea but slightly different implementation):

[Online demo](http://cjam.aditsu.net/#code=q~%7B_mr((%2B_%24)*%7Dg%3B%5D%2C&input=%5B2%202%203%5D)
Input is on stdin in the form `[2 2 3]`.
This is one of those rare occasions where GolfScript's *unfold* operator is useful. It allows us to accumulate the states which the ship passes through, and then count them at the end. Note that the array which is counted includes the initial (input) state but not the final state in which the last element has been reduced to 0.
However, although CJam doesn't have *unfold* its ability to shuffle an array uniformly for only 2 chars counts for a lot and allows it to come out on top.

```
[Demonstration.](https://pyth.herokuapp.com/?code=f!eSXOUQQtZ1&input=%5B2%2C%202%2C%203%5D&debug=0)
How it works:
This is based around Pyth's infinite filter, which tests an expression with increasing inputs until it returns something truthy, then returns the input which caused this to happen. However, the expression that will be tested will not use the input value.
Instead, the expression will modify the input list by decrementing a random entry. This is accomplished via the expression `XOUQQtZ`. This means increase the index `OUQ` in the list `Q` by `tZ`. `OUQ` is a random index in the length of `Q`, and `tZ` is -1. `Q` is initialized to the input list.
After modifying `Q` in this fashion, we take its current value, which `X` returns, take its maximum entry with `eS`, and take the logical not of that value with `!`. This returns a truthy value for the first time when every element of `Q` has been reduced to `0` or below for the first time.
To ensure that the number returned will be exactly the number of times that `Q` was modified, we will start the count at `1`, indicating the the first time this is called, there has been 1 modification. To see what `Q` looks like after each iteration of the code, check out the version [here](https://pyth.herokuapp.com/?code=f!eS%2BXOUQQtZpbQ1&input=%5B2%2C%202%2C%203%5D&debug=0).

# Introduction
You are a friend of a curator for an art museum, who has had the recent delight of getting modern art from four artists (*some of which may give the curator zero pieces of art, young scoundrels*). As this is modern art, all of any given artist's pieces look exactly the same. Your friend wants to use a computer to help decide which order to place these pieces in.
# Program Requirements
Your program must take five integers (passed to a function or inputted through stdin (or someway else)). The first four are the number of paintings supplied by each of the four artists. The last value is an permutation index `i` (counting from 1, not 0). The curator wishes to see the `i`th permutation by lexicographic order of the paintings.
Your program must output this permutation in any reasonable format: e.g. `abbccd` or `[0 1 1 2 2 3]`. The runtime for input totalling fewer than ten paintings must take less than an hour (this should hopefully be no problem).
**You are not allowed to use any in-built functions to work out permutations**
# Examples
Input: 0 1 2 0 2
Given that we have one painting by artist B and two by artist C (and they all look the same), the permutations in lexicographic order are:
>
> ['bcc', '**cbc**', 'ccb']
>
>
>
The highlighted permutation would be the correct output, because it is the second in lexicographic order.
Input: 1 2 0 1 5
>
> ['abbd', 'abdb', 'adbb', 'babd', '**badb**', 'bbad', 'bbda', 'bdab', 'bdba', 'dabb', 'dbab', 'dbba']
>
>
>
## Testing
Here are some tests that should be correct.
```
1 2 4 1 5 - ABBDCCCC
2 2 3 1 86 - ABBCACDC
4 1 2 0 24 - AACACBA
1 4 3 2 65 - ABBCBBDCDC
```
A short piece of code in Python3 that should randomly generate inputs and outputs is available here (not valid for entry, this uses the Python import of permutations):
```
from itertools import permutations
from random import randint
a,b,c,d,n = randint(1,2),randint(1,2),randint(1,3),randint(1,3),randint(1,15)
print(str(a) + " " + str(b) + " " + str(c) + " " + str(d) + " " + str(n) + " - " + str(sorted(set([''.join(p) for p in permutations(a * "a" + b * "b" + c * "c" + d * "d")]))[n-1]))

[Question]
[
After your [disastrous canoe ride](https://codegolf.stackexchange.com/questions/36337/extreme-whitewater-canoeing), you ended up falling off a waterfall at the end of the river rapids. Your canoe exploded, but you managed to survive the explosion. However, your river journey went completely off the map - you have now found yourself lost in the midst of a forest. Luckily, you still have your programming skills, so you decide to carve a program into the side of a tree to help you find your way through the forest. However, there is not much surface area on the tree, so you must make your program as short as possible.
The forest can be described as a `n` by `n` (`n > 5`) square of characters, which will only consist of the lowercase letters `a-z`. An example forest:
```
anehcienwlndm
baneiryeivown
bnabncmxlriru
anhahirrnrauc
riwuafuvocvnc
riwnbaueibnxz
hyirorairener
ruwiiwuauawoe
qnnvcizdaiehr
iefyioeorauvi
quoeuroenraib
cuivoaisdfuae
efoiebnxmcsua
```
You may have noticed that in this forest, there is a diagonal line of `a` characters running through it from the top left corner to the bottom right corner. This is a "path" through the forest which will lead you somewhere if you follow it. Your task is to write a program which will find the singular path. I will now more specifically describe what connotates a "path" in this challenge.
A "path", in this challenge, is defined as a line similiar to one which might have been generated with a [Bresenham algorithm](http://en.wikipedia.org/wiki/Bresenham's_line_algorithm), but with the added requirements that:
* The line must be a minimum 6 characters long
* Each collinear (completely adjacent) group of characters in the line *must be the same length*.
* It will begin at one edge of the forest and end at the opposite edge (see [my comment here](https://codegolf.stackexchange.com/questions/36404/the-forest-path#comment81469_36404) for elaboration)
To explain the second requirement more clearly, consider the following line:
```
aaa
aaa
aaa
aaa
aaa
```
This line is composed of collinear "segments" of characters, each of which are exactly three characters long. It qualifies as a path. Now consider this line:
```
a
aa
a
aa
a
aa
```
This line is composed of collinear "segments" that are not all exactly the same length of characters (some of them are 1 character long and some of them are 2). Thus, this one does not qualify as a path.
Your program, given a map of the forest, identify the characters used in the path. Input is to whatever is convienient (e.g. command line argument, STDIN, `prompt()`, etc.). It cannot be pre initialised into a variable. The first part of the input is a single integer `n` representing the size of the forest (the forest is always a square). After that is a space and then the entire forest as a single string. For instance, the example forest would be presented, as an input, like this:
```
13 anehcienwlndmbaneiryeivownbnabncmxlriruanhahirrnraucriwuafuvocvncriwnbaueibnxzhyirorairenerruwiiwuauawoeqnnvcizdaiehriefyioeorauviquoeuroenraibcuivoaisdfuaeefoiebnxmcsua
```
The output for this would be:
```
a
```
because the path is formed using the letter `a`. There will only be one path in the forest. This is code golf, so the lowest number of characters wins. If you have questions, ask in the comments.

# Lua - ~~506~~ 380 - bytes
I felt kinda bad that you hadn't received any submission for your well thought out challenge, so I threw this together. It was quit fun inferring what the minimum distinguishable properties the path must have from the information you gave. I hope I got it right... AND correctly implemented it.
```
a=io.read"*l"n=a:match("%d+")+0 m=a:match"[a-z]+"o=""for i=1,n do for k=1,n^2,n do o=o..m:sub(i+k-1,i+k-1)end end q={m,o}for g=1,n^2 do for u=1,2 do l=q[u]:sub(g,g)for r=1,n do i=1 t=0 e=0 while i do s,e=q[u]:find(l:rep(r),e+1)if s then x=s-(e-s)-i-1 print(s,i,r,n,r)if x==n or x==n-2 or t==0 then t=t+1 i=s end else i=nil end end if t*r==n then print(l)os.exit()end end end end
```
It can be tested with:
```
lua divisorPath.lua "input"
```
~~If a wild challenger appears, I'll look to golf my code for what it's worth.~~
**Update**: golfed in honour of those who will rise above us. While I was at it I had to fix my code to recognized path going from right to left. Oops.

* `⎕ML←3`: set `ML` to `3`, meaning `⊂` has its APL2 meaning.
* `I←⍞`: read a line from the keyboard and store it in `I`
* `I⊂⍨' '≠I`: split `I` on the spaces
* `{`...`}/`: apply this function to the two resulting strings:
+ `2/⍎⍺`: evaluate the left argument and replicate it twice, giving the matrix size
+ `⍵⍴⍨`: format the right argument using that size
* `F←⊃`: unbox it and store it in `F`.
* `{(⍳≢⍵)⌷¨↓⍵}¨(⊂F),⊂⌽F`: get the diagonals: from each row in both `F` and `⌽F` (vertically mirrored `F`), get the value at column X, where X is its row number
* `(↓⍉F),(↓F),`: get the rows and columns of `F`
* `Z←∪¨`: find the unique values on each row, column and diagonal and store them in `Z`.
Since the 'forest' is rectangular, if there is a valid path it means one of these will consist of only one character, which is the path character, so:
* `Z/⍨1=≢¨Z`: take those subarrays from `Z` that have only one element.
This will display the characters for all valid paths, but since there should be only one that doesn't matter.

# MATLAB - 270 characters
The following defines a function `x` that accepts a forest string as an argument and returns the character representing the valid "path" through the forest subject to the given rules.
```
function F=x(s),A=sscanf(s,'%d%s');n=A(1);A=reshape(A(2:end),n,n);for c=A(:)',B=A==c;for i=1:n,if~mod(n,i),C=[kron(eye(i),ones(n/i,1)),zeros(n,n-i)];for j=0:n-i,f=@(B)sum(sum(B&circshift(C,[0,j]))==n;D=fliplr(B);if f(B)|f(B')|f(D)|f(D'),F=char(c);end;end;end;end;end;end
```
The non-minified version is
```
function F = x(s)
A = sscanf( s, '%d %s' );
n = A(1);
A = reshape( A(2:end), n,n );
for c = A(:)'
B = A==c;
for i = 1:n
if ~mod( n, i )
C = [kron( eye(i), ones( n/i,1 ) ), zeros( n,n-i )];
for j = 0:n-i
f = @(B) sum(sum( B & circshift( C, [0 j] ))) == n;
D = fliplr(B);
if f(B) | f(B') | f(D) | f(D')
F = char(c);
end
end
end
end
end
end
```
The basic premise is to construct a boolean mask for every possible valid path and return any character whose index function in the matrix covers any mask. To accomplish this, only vertical or top-to-bottom backslash-shaped masks are created, but the forest matrix is compared in all four orientiations: identity, flipped, rotated 90°, flipped rotated 90°.
The function runs for any `n`. An example of it being invoked on the commandline is
```
x('13 anehcienwlndmbaneiryeivownbnabncmxlriruanhahirrnraucriwuafuvocvncriwnbaueibnxzhyirorairenerruwiiwuauawoeqnnvcizdaiehriefyioeorauviquoeuroenraibcuivoaisdfuaeefoiebnxmcsua')

## Python - ~~384~~ ~~325~~ 275
This Algorithm basically checks the first and last row of the matrix for matching characters and then calculates the length of each line segment
```
012345
------
aaVaaa|0
aaVaaa|1
aaaVaa|2
aaaVaa|3
aaaaVa|4
aaaaVa|5
```
In the Example above:
The V in the first row is at index 2, the V in the last row at index 4.
So the length of each line segment would be n / (4-2)+1 = 2 with n=6.
It then checks if the line is valid.
In order to find a path from left to right, it swaps rows with columns and does the same thing again.
**Edit:** Can't quite get to 270 (Damn you Python and your damn indentation!!)
```
n,m=raw_input().split()
n,r=int(n),range
t=r(n)
a=[m[i:i+n]for i in r(0,n*n,n)]
for v in a,["".join([a[i][j]for i in t])for j in t]:
for i in t:
for j in t:
p=1-2*(j-i<0);d,c=p*(j-i)+1,v[0][i]
if 6<=sum([v[z][i+(z/(n/d))*p*(n%d==0)]==c for z in t])==n:print c;exit()

Your mission is to write a program that accepts a date in the formats `2014-02-27` (calendar date) and `2014-W09-4` (week date) from standard input and outputs the date in the format it wasn't entered in (to standard output with a trailing newline). The dates must conform to the standard ISO 8601, i.e. with weeks that starts on Mondays and where the first week in a (week) year is the one that contains the first Thursday in the calendar year. You are not allowed to use any libraries, built-in functions or operators that relates to the handling of dates and time.
For example:

# Javascript: 422 characters
Originally this had 825 characters, and was still a bit comprehensible and legible, beside the fact of being golfed. I was sure that it could be reduced in something between 10% to 20%. This answer passed by tons of edits from me and got suggestions from @Ismael Miguel and specially from @DocMax resulting in an extremely-golf-crushed source down to 422 characters, with the side-effect of making it heavily obfuscated, a reduction of almost 49%. Really thanks for both, I wish that you two could get a badge for this. I did not thought that it could be reduced by so much.
Here is the code, 422 characters:
```
x=prompt(E=eval);W=x[f=5]=='W';A=x.match(/\d+/g);y=+A[a=0];for(t="'012011223445569'[z]-30+30*z";q=a%4<1&(a%100>0|a%400<1),a++<y;f=(f+1+q)%7)v=f;z=w=+A[1]-W;r=+A[2];if(W){w+=f>3;h=7*w+r-f;for(z=1;h-q*(z>2)>=E(t);++z);w=1+(10+z--)%12;d=h-q*(z<3)-E(t);y+=z?z>12:-1}else{g=r+E(t)-(w>1&&!q+w-2?2-q:2);d=(f+g)%7;w=0|g/7+(f<4);w=w>11&r-d>26?(++y,1):w<1?(--y,53^v>3):w}alert(y+(W?'-':'-W')+(w>9?'':0)+w+'-'+(!W|++d>9?'':0)+d+'\n')
```
Pretty complex. Here a (somewhat long) partially-ungolfed (but still badly obfuscated) and commented version:
```
x = prompt(E = eval); // Receives input, but has a side-effect of having a strange message in the prompt box.
// Year 0 of the Gregorian calendar (if such thing existed) would start on a 5=Friday. (0=Monday, 6=Sunday)

A = x.match(/\d+/g); // Divide the input in 3 numbers.
y = +A[a = 0]; // Parse the year.
// The t variable is used to create a table with cumulative months length starting from December of the previous year, this table is acessed by using the eval() function.
// Calculate the weekday of 01/01 of the year in the f variable. Do that by counting Gregorian calendar years from 0 until now.
// Count 2 weekdays for leap years and 1 for non-leap years.
// The variable q defines if the year is a leap year.
// The v variable stores the weekday of 01/01 of the prevoius year.
// The % 7 ensures that the weekday are kept in the interval 0-6, where 0 is Monday and 6 is Sunday.
for (t = "'012011223445569'[z] - 30 + 30 * z"; q = a % 4 < 1 & (a % 100 > 0 | a % 400 < 1), a++ < y; f = (f + 1 + q) % 7)
v = f;
z = w = +A[1] - W; // Parse the second number, might be the week number or the month, accordingly to the W.
r = +A[2]; // Parse the third number, might be the week day or the day in the month, accordingly to the W.
// Converts week date to calendar date.
if (W) {
// The expression "7 * (f > 3) - f" maps the offset between the calendar date and the week date in the following manner:

// Obtain the day within the year and store it in h.
w += f > 3;
h = 7 * w + r - f;
// Finds the day offset in the table to the corresponding month.
for (z = 1; h - q * (z > 2) >= E(t); ++z);
// This calculates the day in the month and the month.
w = 1 + (10 + z--) % 12;
d = h - q * (z < 3) - E(t);

The prompt box comes with the message with the serialization of the `eval` function. Ignore this message, it is just a side-effect of golfing some chars.
It passes for all provided test cases. If given invalid input, the behaviour is undefined.
Here are the test cases, had some bugs in previous versions (specially with the last two lines):
```

2008-12-30 <--> 2009-W01-2

2011-04-23 <--> 2011-W16-6

In a quite unorthodox fashion I will give an entry to my own challenge (but I will not accept this answer even if it is the shortest when the time comes), just to show another (much less elegant than the JS-solution) way to attack the problem.
```
I[9],C[9],W[9],Y,M=5,D,y,w,d;main(){for(gets(I);sprintf(C,"%d-%02d-%02d",Y,M,D),sprintf(W,"%d-W%02d-%d",y,w,d),(strcmp(I,C)||puts(W)<0)&&(strcmp(I,W)||puts(C)<0);++D>28+(M^2?M+(M>7)&1^2:!(Y&3)&&(Y%25||!(Y&15)))&&(D=1,M=M%12+1)<2&&Y++,(d=d%7+1)<2&&(M>11&&D>28||M<2&&D<5?(w=1,y++):w++));}
```
I simply simulate the calendars day by day, increasing the month, week, year and week-year as needed. When either the week date or calendar date is equal to what was inputted I output the date in the format it wasn't inputted in (so if the input is invalid it will simply loop forever).
In a slightly more readable form:
```
I[9],C[9],W[9],Y,M=5,D,y,w,d;
main(){
for(
gets(I);
sprintf(C,"%d-%02d-%02d",Y,M,D),
sprintf(W,"%d-W%02d-%d",y,w,d),
(strcmp(I,C)||puts(W)<0)&&
(strcmp(I,W)||puts(C)<0);
++D>28+(M^2?M+(M>7)&1^2:!(Y&3)&&(Y%25||!(Y&15)))&&
(D=1,M=M%12+1)<2&&Y++,
(d=d%7+1)<2&&
(M>11&&D>28||M<2&&D<5?(w=1,y++):w++)

[Question]
[
Assuming A=1, B=2... Z=26, and the value of a word is the sum of these letter values, it is possible to split some words into two pieces such that they have equal values.
For example, "wordsplit" can be broken into two pieces like so: ordsl wpit, because o+r+d+s+l = w+p+i+t.
This was a challenge given to us by my computing teacher - it is an old Lionhead Studios challenge, apparently. I have solved it in Python, and will post my answer shortly.
**Challenge:** The shortest program which can list **all** the possible splits which have equal scores. Note that it only has to list one for each group of letters - ordsl wpit is the same as rdosl wtip, for example. It is easier to list them in the order they come in the word.
**Bonus:**
* If you highlight pairs where both words are valid English words (or some permutation of the letters is), using a word list of some kind. (This could be done by placing an asterisk next to each or some other method, but make it clear.)
* Adding the option for removing duplicates (this should not be the default.)
* Supporting more than two splits, for example, three, four or even n-way splits.

Run with `perl -nE '<code goes here>'`. That 'n' is counted in the code size.
## Respaced:
```

$l = $r;

$l - $r ||

print $_[$_]

## With comments and variable names:
```
# split a line of input by character
@chars = /./g;
# generate all binary masks of same length
for $mask (1 .. 1<<@_) {
# start at "zero"
$left_sum = $right_sum;
# depending on mask, choose left or right count
# 1 -> char goes left; 0 -> char goes right
$mask & 1<<$_ ? $left_sum : $right_sum
-= 64 - ord $chars[$_] # add letter value
for 0 .. $#chars; # for all bits in mask
# if left = right

$mask & 1<<$_ &&
# print it
print $chars[$_]
# ...iterating on all bits in mask
for 0 .. $#chars;
# newline
say ""
}
```
## Some of the tricks used:
* `1..1<<@_` covers the same bit range as `0..(1<<@_)-1` , but is shorter. (note that considering the problem from further away, including the range boundaries multiple times wouldn't result in a wrong output anyway)
* $left\_range and $right\_range aren't reset to actual "0" numeric zero: since we just accumulate and compare them in the end, all we need is them to start at the same value.
* subtracting `64-ord$_[$_]` instead of adding `ord$_[$_]-64` wins an invisible character: since it ends with a delimiter, it makes the space before `for` unnecessary.
* Perl lets you assign to a variable determined by the ternary conditional operator: `cond ? var1 : var2 = new_value`.
* boolean expressions chained with `&&` and `||` are used instead of proper conditionals.
* `$l-$r` is shorter than `$l!=$r`
* will output a newline even on splits that don't balance. Empty lines are ok by the rules! I asked!

My solution is below. It is an almost anti-golf in its size, but it works very well. It supports n-way splits (although computational time becomes very long for any more than about 3 splits) and it supports removing duplicates.
```

def __init__(self, word, splits=2):
if len(word) == 0:
raise ValueError, "word too short!"
if splits == 0:
raise ValueError, "splits must be > 1; it is impossible to split a word into zero groups"
self.word = word
self.splits = splits
def solve(self, uniq_solutions=False, progress_notifier=True):
"""To solve this problem, we first need to consider all the possible
rearrangements of a string into two (or more) groups.
It turns out that this reduces simply to a base-N counting algorithm,
each digit coding for which group the letter goes into. Obviously
the longer the word the more digits needed to count up to, so
computation time is very long for larger bases and longer words. It
could be sped up by using a precalculated array of numbers in the
required base, but this requires more memory. (Space-time tradeoff.)
A progress notifier may be set. If True, the default notifier is used,
if None, no notifier is used, and if it points to another callable,
that is used. The callable must take the arguments as (n, count,
solutions) where n is the number of iterations, count is the total
iteration count and solutions is the length of the solutions list. The
progress notifier is called at the beginning, on every 1000th iteration,
and at the end.

an empty list. Duplicate solutions are removed if the uniq_solutions

[Question]
[
[The Universal Crossword](https://www.puzzlesociety.com/crosswords) has a set of [guidelines](https://docs.google.com/document/d/1ORNpKwGG7RedypfnYwgOfkTUc0jNZ7FKRRTVWDmTfl8/edit) for crossword puzzle submissions.
In this challenge we are going to be concerned with their rules for hidden word themes. A hidden word clue consists of a clue and a word. It can either be a
"word break" or a "bookend".
For a word break the word must not appear as a contiguous substring of the clue, but if all the spaces are removed from the clue, then it is a contiguous substring with a non-empty prefix and suffix. Some examples:
* `POOR HOUSE`, `RHO`: is valid. Solution: `POO***R HO***USE`
* `IMPROPER USE`, `PERUSE`: is not valid. It appears separated by a space: `IMPRO***PER USE***`, but the suffix is empty.
* `SINGLE TRACK`, `SINGLET`: is not valid. It appears separated by a space: `***SINGLE T***RACK`, but the prefix is empty.
* `PLANE TICKET`, `ET`: is not valid. The word appears separated by a space: `PLAN***E T***ICKET`, but it also appears contiguously: `PLANE TICK***ET***`.
For a bookend the word must appear as a combination of a non-empty prefix and a non-empty suffix of the clue, but is not a contiguous substring. Bookends may span word breaks, but are not required to. The clue must not appear as a contiguous substring to be a valid bookend.
* `SINGLE TRACK`, `SICK`: is valid. Solution: `***SI***NGLE TRA***CK***`
* `YOU MUST DOT YOUR IS AND CROSS YOUR TS`, `YURTS`: is valid. Solution: `***Y***OU MUST DOT YOUR IS AND CROSS YO***UR TS***`
* `STAND CLEAR`, `STAR`: is valid, even though there are two solutions: `***STA***ND CLEA***R***` and `***ST***AND CLE***AR***`
* `START A WAR`, `STAR`: is not valid since the word is a prefix of the clue.
* `TO ME`, `TOME`: is valid. It can be split multiple ways including ways with empty prefixes and suffixes.
* `TWO BIRDS WITH TWO STONE`, `TONE`: is not valid since the word is a suffix of the clue
* `IMPROPER USE`, `PERUSE`: is not valid. It appears as a suffix and is not a contiguous substring: `IMPRO***PER USE***`, but the prefix needs to be non empty for a bookend.
You will take as input a word (consisting of letters `A`-`Z`) and a clue (consisting of letters `A`-`Z` and spaces) and you must determine if the word is a valid solution to the clue by the above rules.
If the input is a valid pair you must output one consistent value, if it is not you must output a distinct consistent value.
This is [code-golf](/questions/tagged/code-golf "show questions tagged 'code-golf'") so the goal is to minimize the size of your source code as measured in bytes.
## Test cases
Valid:
```
POOR HOUSE, RHO
SINGLE TRACK, SICK
YOU MUST DOT YOUR IS AND CROSS YOUR TS, YURTS
STAND CLEAR, STAR
TO ME, TOME
IN A PICKLE, NAP
```
Invalid:
```
IMPROPER USE, PERUSE

This approach allows us to avoid treating the two cases of bookends and word breaks as separate:
* `-.@rxin*` Not in the unaltered string
* `*` And...
* `-.&' '` Remove spaces from haystack
* `#\@]` Create the integers 1..n (where n is length of haystack)
* `,&#` Create the integers n and m, the lengths of needle and the haystack. I'll explain why below.
* `-.` Remove n and m from 1..n (again, why below). Call this our "rotation list".
* `|."{[` Do every rotation of 1..n in our rotation list. The rotations we are leaving out are precisely the ones where our haystack abuts the left or right side, which are the illegal ones. We now have a matrix, with each row representing a legal rotation.
* `#@[>:` In every row, change the numbers 1..m (where m is length of needle) to 1 and the rest to 0, so now we have a matrix of the legal rotations of, eg, `1 1 1 0 0 0 0 0` (if the needle had length 3).
* `]#~` Now use the rows of legal 0-1 masks to filter the no-spaces input. These represent all possible bookends and word breaks.
* `[e.` Is the needle in any of those?

* `-.@rxin` Does not appear in unaltered string
* `*` and...
* `(rxin g)` Does appear in the no-spaces `' '-.~]` string, after that string has its first and last elements removed `g=.}:@}.`
* `+.` or...
* `-~&#(g=.}:@}.)@(]\.)` Matches one of the outfixes (of appropriate length `-~&#`) after the set of all such outfixes has its first and last elements removed `}:@}.`.

[Question]
[
A [fixed-point combinator](https://en.wikipedia.org/wiki/Fixed-point_combinator) is a higher order function \$\mathrm{fix}\$ that returns the fixed point of its argument function. If the function \$f\$ has one or more fixed points, then $$\mathrm{fix} f=f(\mathrm{fix} f).$$
The combinator \$Y\$ has such properties. Encoded in lambda calculus: $$Y=\lambda f.(\lambda x.f(x x))\ (\lambda x.f (x x))$$
You can extend a fixed-point combinator to find the fixed point of the \$i\$-th function out of \$n\$ given functions.
$$
\mathrm{fix}\_{i,n}f\_1\dots f\_n=f\_i(\mathrm{fix}\_{1,n}f\_1\dots f\_n)\dots(\mathrm{fix}\_{n,n}f\_1\dots f\_n)
$$
As an extension to the \$Y\$ combinator:
\begin{alignat\*}{2}
Y\_{i,n}=\lambda f\_1\dots f\_n.&((\lambda x\_1\dots x\_n.f\_i&&(x\_1x\_1\dots x\_n)\\
& && \dots\\
& && (x\_nx\_1...x\_n)))\\
&((\lambda x\_1\dots x\_n.f\_1&&(x\_1x\_1\dots x\_n)\\
& && \dots\\
& && (x\_nx\_1...x\_n)))\\
&\dots\\
&((\lambda x\_1\dots x\_n.f\_n&&(x\_1x\_1\dots x\_n)\\
& && \dots\\
& && (x\_nx\_1...x\_n)))
\end{alignat\*}
Example:
\begin{alignat\*}{3}
Y\_{1,1}&=Y && &&&\\
Y\_{1,2}&=\lambda f\_1f\_2.&&((\lambda x\_1x\_2.f\_1&&&(x\_1x\_1x\_2)\\
& && &&& (x\_2x\_1x\_2))\\
& &&((\lambda x\_1x\_2.f\_1&&&(x\_1x\_1x\_2)\\
& && &&& (x\_2x\_1x\_2))\\
& &&((\lambda x\_1x\_2.f\_2&&&(x\_1x\_1x\_2)\\
& && &&& (x\_2x\_1x\_2))
\end{alignat\*}
**Your task** is to write a *variadic* fixed-point combinator \$\mathrm{fix}^\*\$ that finds and returns the fixed-points of all given functions.
$$
\mathrm{fix}^\*f\_1\dots f\_n=\langle\mathrm{fix}\_{1,n}f\_1\dots f\_n,\dots,\mathrm{fix}\_{n,n}f\_1\dots f\_n\rangle
$$
While the details are up to you, I suggest your program accepts a list of functions and returns a list of their fixed points.
**For example**, take the following pseudo-Haskell functions your program should be able to solve (basically \$\mathrm{fix}\_{i,2}\$):
```
-- even/odd using fix* with lambdas as function arguments
f = (\f g n -> if n == 0 then True else (g (n - 1)))
g = (\f g n -> if n == 0 then False else (f (n - 1)))
isEven = head $ fix* [f,g]
isOdd = tail $ fix* [f,g]
-- mod3 using fix* with lists as function arguments
h1 [h1, h2, h3] n = if n == 0 then 0 else h2 (n - 1)
h2 [h1, h2, h3] n = if n == 0 then 1 else h3 (n - 1)
h3 [h1, h2, h3] n = if n == 0 then 2 else h1 (n - 1)
mod3 = head $ fix* [h1, h2, h3]
```
**Example (ungolfed) implementation**:
>
> [Bruijn](https://bruijn.marvinborner.de): `y* [[[0 1] <$> 0] [[1 <! ([[1 2 0]] <$> 0)]] <$> 0]`
>
>
>
**Rules**:
* Use any language you like, as long as `fix*` can accept functions and return their fixed points in your preferred format
* `code-golf`, the shortest implementation in bytes wins
* You can assume a fixed point exists for every given function, you *do not* need to solve the halting problem
* **Bonus**: Subtract 10 from your byte count if your solution does not use recursion (i.e. does not use the feature of your language that's typically responsible for recursion; fixed-point combinators are allowed)
* Have fun!

A recursive function that takes a list of functions and returns a list of functions. The input list of functions should be a list of mutually recursive functions. Each function within this list should take a list of functions as an argument, and return a function that makes use of one or more members of the function list.

```
Based on [*@user*'s Java answer](https://codegolf.stackexchange.com/a/229753/52210) for [the related *Implement Fix2 combinator* challenge](https://codegolf.stackexchange.com/questions/229602/implement-fix2-combinator), as well as [my Java answer](https://codegolf.stackexchange.com/a/266084/52210) for [the related *Golfed fixed point combinator* challenge](https://codegolf.stackexchange.com/questions/1064/golfed-fixed-point-combinator).
**Explanation:**
```
interface C{ // Completed Function interface
Object t(Object o);} // Using a function that transforms a given Object
interface F{ // Function interface
C f();} // A wrapper to pass the 'Completed Function' as function
interface P{ // Program interface
C c(F[]f); // Which takes an array of 'Function's as argument,
// and returns a 'Completed Function'
static F[]g(P[]a){ // Recursive function that accepts an array of 'Program's as argument,
// and returns an array of 'Function's
return java.util.Arrays.stream(a)
// Convert the given 'Program's-array to a generic Stream
.map(p-> // Map each 'Program' in this Stream to:
(F) // A casted 'Function' (necessary since it's a generic instead of typed Stream)
()-> // which wraps:
p.c( // A completed call to its own 'Program' interface
g( // Using a recursive call to its own function
a)) // with the given 'Program's-array as argument
.toArray(F[]::new);}}
// After the map: convert the Stream to a 'Function's-array
```
The method to call is `P::g`, which takes an array of `P` as argument and returns an array of `F`. To obtain a completed function `C` from an `F`, we can call `F::f` on it. `P` represents the function to be fixed, and its method `c` takes `F` as argument to prevent immediate evaluation, returning a `C` that represents a complete function to transform a given Object `o` with `C`'s `t(o)`.
**Example even/odd implementation:**
```
P[] evenOddFix = {
func -> n -> (int)n == 0 ? true : func[1].f().t((int)n-1),
func -> n -> (int)n == 0 ? false : func[0].f().t((int)n-1)
};
F[] evenOddFunctions = P.g(evenOddFix);
C evenFunc = evenOddFunctions[0].f(),
oddFunc = evenOddFunctions[1].f();
Object evenResult = evenFunc.t(input),
oddResult = oddFunc.t(input);

A lambda taking a list of mutually recursive functions and returning a list of functions that return functions. Unlike R, Python doesn’t have lazy evaluation of function arguments so an extra step is needed to delay function evaluation from happening within the call to `y` itself; I think this is analogous to the [Java answer from @KevinCruijsson](https://codegolf.stackexchange.com/a/266085/42248).
The even odd and Collatz examples here look like this:
```
even_odd_fix = [
lambda f:lambda n:n==0 or f[1]()(n-1),
lambda f:lambda n:n!=0 and f[0]()(n-1)
]
collatz_fix = [
lambda f:lambda n,d=0:d if n==1 else f[int(n%2+1)]()(n,d+1),
lambda f:lambda n,d:f[0]()(n//2,d),
lambda f:lambda n,d:f[0]()(3*n+1,d)
]
even_odd = [f() for f in y(even_odd_fix)]
collatz = y(collatz_fix)[0]()
[print(x, "Even:", even_odd[0](x), "Odd:", even_odd[1](x), "Collatz:", collatz(x)) for x in range(1,11)]
```
Note that the functions returned must be called without an argument to return the actual useful function.

[Question]
[
There have already been challenges about computing the [exponential](https://codegolf.stackexchange.com/questions/230784/to-raise-e-to-the-power-of-a-matrix) of a matrix , as well as computing the [natural logarithm](https://codegolf.stackexchange.com/questions/262711/vanilla-natural-logarithm-challenge)
of a number. This challenge is about finding the (natural) logarithm of matrix.
You task is to write a program of function that takes an invertible \$n \times n\$ matrix \$A\$ as input and returns the [matrix logarithm](https://en.wikipedia.org/wiki/Logarithm_of_a_matrix) of that matrix.
The matrix logarithm of a matrix \$ A\$ is defined (similar to the real logarithm) to be a matrix \$L\$ with \$ exp(L) = A\$.
Like the complex logarithm the matrix logarithm is not unique, you can choose to return any of the possible results for a given matrix.
Examples (rounded to five significant digits):
```
log( [[ 1,0],[0, 1]] ) = [[0,0], [0,0]]
log( [[ 1,2],[3, 4]] ) = [[-0.3504 + 2.3911i, 0.9294 - 1.0938i], [1.3940 - 1.6406i, 1.04359 + 0.75047i]]
log( [[-1,0],[0,-1]] ) = [[0,pi],[-pi,0]] // exact
log( [[-1,0],[0,-1]] ) = [[0,-pi],[pi,0]] // also exact
log( [[-1,0],[0,-1]] ) = [[pi*i,0],[0,pi*i]] // also exact
log( [[-1,0,0],[0,1,0],[0,0,2]] ) = [[3.1416i, 0, 0], [0, 0, 0], [0, 0, 0.69315]]
log( [[1,2,3],[4,5,4],[3,2,1]] ) = [[0.6032 + 1.5708i, 0.71969, -0.0900 - 1.5708i],[1.4394, 0.87307, 1.4394],[-0.0900 - 1.5708i, 0.71969, 0.6032 + 1.5708i]]
```
If you want to try out more examples use the function `digits 5 matrix logarithm` followed by a matrix in [Wolfram Alpha](https://www.wolframalpha.com)
Rules:
* You can Input/Output matrices as nested lists
* You can Input/Output complex numbers as pairs of real numbers
* You can assume the logarithm of the input matrix exists
* Your result should be accurate up to at least 5 significant (decimal) digits
* You only have to handle matrices of sizes \$2\times2\$ and \$3\times3\$
* You program may return different results when called multiple times on the same input as long as all of them are correct
* Please add builtin answers (including libraries) to the community wiki instead of posting them separately
* This is [code-golf](/questions/tagged/code-golf "show questions tagged 'code-golf'") the shortest solution (per language) wins

I didn't initially spot the 'invertible' in the challenge specification, so tried to use [this other method from Wikipedia](https://en.wikipedia.org/wiki/Logarithm_of_a_matrix#Power_series_expression) which works for non-diagonalizable matrices `M`, but with the restriction that `norm(M-I)` must be `<1`.
In many cases, this can be extended to matrices with larger-valued elements, using `L == log( M %*% X) == log( M ) + log( X )`: in these cases, we divide the matrix `M` by a sufficiently-large power-of-2 `l`, and add `l` times the log of 2x the identity matrix to the result.
Nevertheless, this is not fully-general, and fails for matrices `M` that cannot be scaled to satisfy `norm(M-I)<1` (for instance, the matrix `[[1,2],[3,4]]`).

[Question]
[
A twin of [this](https://codegolf.stackexchange.com/questions/249186/fix-my-fizzbuzz).
FizzBuzz is where a range of positive integers is taken, and numbers divisible by 3 are replaced with "Fizz", divisible by 5 with "Buzz" and divisible by 15 with "FizzBuzz". For example, FizzBuzz from 1 to 10 is `1, 2, Fizz, 4, Buzz, Fizz, 7, 8, Fizz, Buzz`.
Your challenge is to, given a list of Fizzes, Buzzes, FizzBuzzes and a value representing an integer (I'm going to use Int), determine if it can be arranged into valid FizzBuzz.
For example, `Int, Fizz, Fizz, Buzz` can be arranged into `Fizz, Buzz, Int, Fizz` (for example 9,10,11,12) which is valid. But `Buzz, Fizz, Buzz` cannot, as the two `Buzz` need to be five values apart.
You may choose any four values to represent Fizz, Buzz, FizzBuzz and Int.

Takes `Int` as `1`, `Fizz` as `3`, `Buzz` as `5`, `FizzBuzz` as `15`.
## Explanation
One key observation is that, if we replace all the integers with a single value `Int`, then the FizzBuzz sequence has a period of 15:
```
Int
Int
Fizz
Int
Buzz
Fizz
Int
Int
Fizz
Buzz
Int
Fizz
Int
Int
FizzBuzz
```
It is rather easy to prove that this is in fact the case. *Hint: start by placing the multiples of 3 and 5.*
What we can therefore do is focus on the first 15 numbers. From each of these numbers, we can make a little subsequence of numbers whose length is the same as the length of the input, and determine whether the sorted values (where the integers become `Int`) are the same as the input.
How do we do this? We use a cool trick whereby we get the maximum number out of `[1, 3, 5, 15]` such that the current number is divisible by that number. Since `Int` is `1`, all numbers that are not multiples of 3 or 5 correspond to `Int`. Multiples of 3 but not of 5 correspond to `Fizz`, etc. We can eventually generate this sequence of 1s, 3s, 5s and 15s.
Sorting the input and comparing it against the sorted values of the subsequence will reveal whether the input is shuffled FizzBuzz or not.

Lean is a theorem prover and programming language. It's also as of writing the [Language of the Month](https://codegolf.meta.stackexchange.com/q/23916/56656)!
What tips do people have for golfing in Lean? As always, tips should be specific to to Lean (e.g. "Remove comments" is not an answer), and stick to a single tip per answer.
[Answer]
# Introductions
If you've just finished the natural number game you may be familiar with the `intro` tactic, this can be used to create implications / functions. However this tactic is rarely the golfiest.
If your intro is the first part of your proof then an implicit forall is probably better. Compare:
```
def q:list ℕ→ℕ:=by{intro x,induction x,exact 0,exact x_hd+x_ih}
```
with
```
def q(x:list ℕ):ℕ:=by{induction x,exact 0,exact x_hd+x_ih}
```
This is frequently always your best option. However if the type of your function can be inferred you have other options.
```
def f:ℕ→ℕ:=by{intro x,exact x+3}
def f(x:ℕ):ℕ:=by{exact x+3}
def f:=λx,by{exact x+3}
def f(x):=by{exact x+3}
```
These are ordered by length so implicit forall (the last option is still implicit forall) is the shortest. But the lambda can expression can have the `def f:=` removed if the function is your submission, making it the shortest in that case.
[Answer]
## Use `by` instead of `begin ... end`
`by` can be shorter than `begin` and `end`.
```
def foo(m:ℕ):m=m:=begin refl,end
```
is longer than
```
def bar(m:ℕ):m=m :=by refl
```
You can also use it for multiple tactics, though you'll need to encase the tactics in braces, as Wheat Wizard pointed out. For example, `by{rw add_assoc,refl}` is shorter than `begin rw add_assoc,refl end`.
[Answer]
## The `;` and `<|>` combinators.
`;` makes it so that all subgoals created by the last tactic have the next tactic applied; for example, `lemma asda (n : ℕ) : n = n := by { induction n; refl }` is a valid proof. As a bonus, it also allows you to not use the braces (e.g. `def k(n:ℕ):n=n:=by induction n;refl`).
The `<|>` is a bit more niche, but still useful; it allows you to do one tactic, and if it fails, the other instead. It also allows for no braces (although this is longer than `,`, so not as useful). For example:
```
example(x):0+x=x:=by induction x;refl<|>rw nat.zero_add
```

[Question]
[
## Background
The [fixed-point combinator](https://en.wikipedia.org/wiki/Fixed-point_combinator) \$\textsf{fix}\$ is a higher-order function that computes the fixed point of the given function.
$$\textsf{fix}\ f = f\ (\textsf{fix}\ f)$$
In terms of programming, it is used to implement recursion in lambda calculus, where the function body does not normally have access to its own name. A common example is recursive factorial (written in Haskell-like syntax). Observe how the use of `fix` "unknots" the recursive call of `fac`.
```
fix f = f (fix f)
fac = fix facFix where
facFix fac' n =
if n == 0
then 1
else fac' (n - 1) * n
-- which is equivalent to the following recursive function:
fac n =
if n == 0
then 1
else fac (n - 1) * n
```
Now, have you ever thought about how you would do the same for *mutually* recursive functions? [This article](http://okmij.org/ftp/Computation/fixed-point-combinators.html#Poly-variadic) describes the fully general \$\textsf{Y}^\*\$ combinator, which takes a list (or equivalent) of unknotted definitions and returns the list of mutually recursive ("knotted") functions. This challenge will focus on a simpler situation with exactly 2 mutually recursive functions; the respective combinator will be called `fix2` throughout this challenge.
A common example of mutual recursion is `even` and `odd` defined like this:
```
even n =
if n == 0
then true
else odd (n - 1)
odd n =
if n == 0
then false
else even (n - 1)
```
The unknotted version of these would look like this (note that mutually recursive definitions should have access to *every single function* being defined):
```
evenFix (even, odd) n =
if n == 0
then true
else odd (n - 1)
oddFix (even, odd) n =
if n == 0
then false
else even (n - 1)
```
Then we can knot the two definitions using `fix2` to get the recursive `even` and `odd` back:
```
fix2 (a, b) = fix (\self -> (a self, b self))
where fix f = f (fix f)
let (even, odd) = fix2 (evenFix, oddFix)
```
## Challenge
Implement `fix2`. To be more precise, write a function or program that takes two unknotted black-box functions `fFix` and `gFix` and a non-negative integer `n`, and outputs the two results `(f(n), g(n))` of the knotted equivalents `f` and `g`. Each `f` and `g` is guaranteed to be a function that takes and returns a non-negative integer.
You can choose how `fFix` and `gFix` (and also `fix2`) will take their arguments (curried or not). It is recommended to demonstrate how the even-odd example works with your implementation of `fix2`.

The method to call is `P::z`, which takes two-element array of `P`s and returns a two-element array of `L`'s. To obtain a completed function (`C`) from an `L`, one has to call `L::g` on it. `P` represents a function to be fixed, and its `a` method takes a two-element array of `L`s to prevent evaluation immediately, returning a `C` that represents a complete function that an `int` `n` can be applied to.

This is very similar to Anders Kaseorg's answer, but it takes a lot more effort to avoid stack overflows and infinite recursion in Scala because it doesn't have lazy evaluation by default.
```

//A function that needs to be fixed. Takes a by-name parameter, a lazily evaluated
//list that contains complete functions, and returns a complete function
type T=(=>Stream[R])=>R
//The meat of the answer. This is practically the same as the Haskell answer.
def>(f:Stream[T]): Stream[R] =
f.map( //For every incomplete function in f
_( //apply it to
>(f))) //the result of applying > on f again (not immediately evaluated)
```
A possible implementation of `evenFix` and `oddFix`:
```
val evenFix: T = fns => n => if (n == 0) 1 else fns(1)(n - 1)
val oddFix: T = fns => n => if (n == 0) 0 else fns(0)(n - 1)
```
Note that since `fns` is a by-name parameter, using it more than once causes it to be evaluated again. It can also not be pattern-matched on, since that causes it to be evaluated.

Create the shortest function, program, or expression that calculates a sequence of squarefree palindromic numbers.
A squarefree number is one which is not evenly divisible by a square number (i.e. does not contain a repeated prime factor). For example, \$44 = 2^2 \times 11\$ is not squarefree, whereas \$66 = 2\times3\times11\$ is.

### Helper function
The helper function **g** checks simultaneously whether **i** is palindromic and squarefree. The variable **d** is used as a counter to test the divisors and as a decreasing digit index. The variable **k** is used as an increasing digit index. Both **i** and **k** are defined in the wrapper.
```
g = d => // g is a recursive function taking a counter d
i[d] && // if i[d] is defined
i[d] - i[k++] ? // and it's not equal to i[k] (increment k afterwards):
1 // i is not palindromic: force a truthy result
: // else:
i % d-- ** 2 ? // if d² is not a divisor of i (decrement d afterwards):
g(d) // do a recursive call
: // else:
d // return d (0 if i is squarefree)
```
### Wrapper
The main function decrements **n** whenever **g** returns **0** and stops when **n = 0**.
```
f = (n, i) => // f is a recursive function taking an index n
g(i += k = '') || // set k to a zero'ish empty string,
// coerce i to a string
// and invoke g with d = i
n-- ? // if the above call was truthy or n is not equal to 0:
f(n, -~i) // do a recursive call with i + 1
: // else:
i // success: return i

[Question]
[
I often have to take character data and categorize it numerically at work. A common thing I do is to take character type variables and convert them to numeric type characters, keeping same categories according to the level of work I'm doing. (The longer the substring, the more in depth and specific, shorter substrings for broad level). Enough backstory...
The challenge: **In as few bytes as possible,** convert the input part A, *a vector/list of unique strings*, into the output, a *vector/list of numbers*, keeping unique categories within the length of substrings the same length, which is input part B. Feel free to ask questions for clarification.
**Input:**
1. w, Vector/list of unique strings of equal character length. `n <= 10`
* These strings may be any combination of uppercase letters and numbers. Sorry if it seems my examples follow a pattern, I just created them after a similar pattern I see in the data I work with.
* Some random examples of what input could look like: "A1", "7LJ1", "J426SIR", "4AYE28TLSR", or any other random combination of uppercase letters up to 10 characters. To repeat: Each element in the vector/list will be the same length.
* Input may already be ordered by group, or non-contiguous, meaning elements lying within one group may be separated by elements of a different group. (See example 2)
2. s, where `1 <= s <= n`
**Output:**
Output should have the indexes of the sorted, de-duplicated, trimmed values. See example 2. (I've included comments in my output to clarify, this is not required) This can be 0-based or 1-based index, as per your language uses.
**Example Input 1:**
```
#Input already alphabetized, but this input is not always guaranteed
s = 3, w =
[ABC01,
ABC11,
ABC21,
ABD01,
ABE01,
ABE02,
ACA10,
ACA11,
ACB20,
ACB21]
```
**Example Output 1:**
```
[1, #ABC
1,
1,
2, #ABD
3, #ABE
3,
4, #ACA
4,
5, #ACB
5]
```
**Example Input 2:**
s = 4, w =
```
[X1Z123,
X1Z134,
X1Y123,
X1Y134,
X1Y145,

X2Z134,
X1X255,
X1Y124,
X2Z222,
X2Z223,

```
**Example 2 Output:**
```
#Categorize by order of appearance

2, #X1Y1

[Question]
[
Flip flop is a memory / arithmetic game that I played in high school. Some number of players stand in a circle. The players take turns. On the `n`th turn, the current player checks:
1. What is the largest power of 7 dividing n?
2. How many instances of the digit 7 does the decimal representation of n contain?
3. What is the largest power of 8 dividing n?
4. How many instances of the digit 8 does the decimal representation of n contain?
Let `FLIPS(n)` be the sum of the power of 7 dividing `n` and the number of `7`'s n contains. For example, `FLIPS(7)=2` (divisible by 7 once, contains one 7), `FLIPS(14) = 1` (divisible by 7 once, contains zero 7's), `FLIPS(17)=1` (not divisible by 7, contains one 7).
Let `FLOPS(n)` be the sum of the power of 8 dividing `n` and the number of `8`'s `n` contains.
On a player's turn, if `FLIPS(n)=FLOPS(n)=0` they say `n`. Otherwise, they first say "flip" `FLIPS(n)` times and then say "flop" `FLOPS(n)` times.
If `FLIPS(n)` is odd, the direction of play swaps (from counterclockwise to clockwise or from clockwise to counterclockwise). The next `FLOPS(n)` players in the new play order are skipped.
## Task
Write a program that takes a pair of integers `(num_players, turns)` and plays Flipflop with a group of `num_players` players for `turns` turns. Output should be a list of the `current_player` on the nth turn. The players are numbered 1 through num\_players. The player to the left of player 1 is player num\_players. (If it's more convenient to label the players `0` to `num_players - 1`, that is fine too.) Play begins with player 1 in counterclockwise order.
## Example:
I'll give an example with 5 players. For the first 6 turns nothing interesting happens:
1. Player 1 says "1" (CCW)
2. Player 2 says "2" (CCW)
...
5. Player 5 says "5" (CCW)
6. Player 1 says "6" (CCW)
7. Player 2 says "flipflip" (still CCW `FLIPS(7)=2` is even)
8. Player 3 says "flopflop" (CCW, skip players 4 and 5)
9. Player 1 says "9" (CCW)
...
14. Player 1 says "flip" (now CW play order)
15. Player 5 says "15" (CW)
16. Player 4 says "flop" (CW)
17. Player 2 says "flip" (now CCW)
18. Player 3 says "flop" (CCW)
19. Player 5 says "19" (CCW)
The 70's and 80's have a lot of activity. When trying to actually play this game, it is hard to remember where in this 20 digit sequence you are (though 700 / 800 is much worse).
69. Player 4 says "69" (CW)
70. Player 3 says "flipflip" (still CW)
71. Player 2 says "flip" (CCW)
72. Player 3 says "flipflop" (CW)
73. Player 1 says "flip" (CCW)
74. Player 2 says "flip" (CW)
75. Player 1 says "flip" (CCW)
76. Player 2 says "flip" (CW)
77. Player 1 says "flipflipflip"(CCW)
78. Player 2 says "flipflop" (CW)
79. Player 5 says "flip" (CCW)
80. Player 1 says "flopflop" (CCW)
81. Player 4 says "flop" (CCW)
82. Player 1 says "flop" (CCW)
83. Player 3 says "flop" (CCW)
84. Player 5 says "flipflop" (CW)
85. Player 3 says "flop" (CW)
86. Player 1 says "flop" (CW)
87. Player 4 says "flipflop" (CCW)
88. Player 1 says "flopflopflop"(CCW)
89. Player 5 says "flop" (CCW)
90. Player 2 says "90" (CCW)

A dyadic link that takes the number of turns as the left argument and number of players as the right. Players and numbered from 0 to *number of players - 1* and play starts with player 1. Currently returns the start player and the current player after each turn (so 101 players in total); this could easily be changed to omit the final one at the cost of a byte.
As a bonus, [here's a version](https://tio.run/##y0rNyan8//9Rw5xDC1UfNe473P6oceuh3Q93bDq05OGubqUot0dNa06sV/JSAUoCVT1qmJv1aOM6rsMtulrHuh41zDi2FqggwND6cIvqw53TuFyOdB9aqv1wd@/J6Yf3metYHF5@dM/hjSenP2rcCdSteWg50JiHO1oeNe561LgFas/RPUATH@7qAxrkDcRHpmUBSaA6PYXI//8f7lzrcHj5oaX/DQ0M/psDAA) that prints the player and what they say.

[Coding Convention Conversion](/questions/70180/coding-convention-conversion)
(19 answers)
Closed 4 years ago.
## Story
In an unnamed company, some people use Java and some use C++. This was always a nuisance, and they kept on arguing which single language they should all be using. To settle the dispute, the management decided that they'll buy a translator program that will be able to rewrite their C++ programs to Java and vice versa. An important part of the translator will be a routine that will rewrite all the identifiers. This is because Java coders in the company write multiword identifiers in a different way than C++ coders in the company do. We will now describe both methods. In Java a multiword identifier is constructed in the following manner: the first word is written starting with a lowercase letter, and the following ones are written starting with an uppercase letter, no separators are used. All other letters are lowercase. Examples of Java identifiers are `javaIdentifier`, `longAndMnemonicIdentifier`, `name` and `kSP`.In C++ people use only lowercase letters in their identifiers. To separate words they use the underscore character '\_'. Examples of C++ identifiers are `cpp_identifier`, `long_and_mnemonic_identifier`, `name` (here Java and C++ people agree), and `k_s_p`.
## Task
Write the identifier translation routine/function/etc. Given an identifier, detect whether it is a Java identifier or C++ identifier (as defined below) and translate it to the other dialect. Translation must preserve the order of words and must only change the case of letters and/or add/remove underscores. You may assume all input to be valid, as checking was done for you in the superroutine.
## More formally
A Java identifier only contains characters from [a-zA-Z] and starts with a lowercase letter. Every uppercase character is a word boundary.
A C++ identifier only contains characters from [a-z\_] and additionally doesn't start or end with an underscore nor does it contain two adjacent underscores anywhere within. Every underscore is a word boundary.
Translation: switch every word boundary, that is, if it was an underscore, remove it and capitalize the following letter, if it was uppercase, prepend an underscore and lowercase the letter.
## Input
The input consists of one line that contains an identifier. It consists of letters of the English alphabet and underscores. Other standard input styles are also valid.
## Output
If the input identifier is a Java identifier, output/return its C++ version. If it is a C++ identifier, output/return its Java version. You may assume it will be at least one of those (both is possible).
## Examples
```
long_boring_identifier | longBoringIdentifier
otherWay | other_way
same | same
getHTTP | get_h_t_t_p
invalid_Input | <undefined>
```
All the standard rules apply, none of the standard loopholes are allowed.

[Question]

## Background
Though this is a bit late for Pi Day, I saw an article about [Pilish](https://en.wikipedia.org/wiki/Pilish) and thought it would make a great challenge. Pilish is created by using a sequence of words where each word's length corresponds to a digit of pi.
Example from Wikipedia:
>
> The following Pilish poem (written by Joseph Shipley) matches the first 31 digits of π:
>
>
>
> >
> > But a time I spent wandering in bloomy night;
> >
> > Yon tower, tinkling chimewise, loftily opportune.
> >
> > Out, up, and together came sudden to Sunday rite,
> >
> > The one solemnly off to correct plenilune.
> >
> >
> >
>
>
>
## Rules
Again, from Wikipedia (emphasis mine):
>
> In order to deal with occurrences of the digit zero, the following rule set was introduced (referred to as *Basic Pilish*):
>
>
> In **Basic Pilish**, each word of n letters represents
>
> (1) The digit n if n < 10
>
> (2) The digit 0 if n = 10
>
> Since long runs of small non-zero digits are difficult to deal with naturally (such as 1121 or 1111211), another rule set called Standard Pilish was introduced:
>
>
> In **Standard Pilish**, each word of n letters represents
>
> (1) The digit n if n < 10
>
> (2) The digit 0 if n = 10
>
> (3) Two consecutive digits if n > 10
>
> (for example, a 12-letter word, such as "sleepwalking," represents the digits 1,2)
>
>
>
1,0 cannot combine to become 10, because that would ignore the one (zero already becomes ten).
No more than two consecutive digits will ever be combined. So no words will ever be more than 99 characters long.
---
## Challenge
Given a delimited string or list of words, and optionally a generator function or stream for the digits of pi, determine if the input is `Incorrect`, `Basic`, or `Standard` Pilish, with the output being some distinct value for each.
Code golf: shortest code wins.
The input parameter for pi can be a generator function that you create and pass into your function, or a builtin, or it could be a string of digits. The most digits of pi that could be required for an input of `n` words is `2*n`, because no more than two digits can be "consumed" by a single word. So just don't worry about needing to create and golf a generating function for pi, since we already have that challenge. For testing purposes, you can also utilize the [first million digits of pi](https://www.piday.org/million/).
Note that if it is valid Basic Pilish, then it's also valid Standard Pilish, but the output should be your value for `Basic`.
Words will only contain letters of upper and lowercase. Optionally, you may remove all non-letter and non-whitespace characters beforehand, so that `I don't.` becomes `I dont`, for example.
## Examples
**Basic**
```
yes
```
```
But I dont
```
```
But a time I spent wandering in bloomy night Yon tower tinkling chimewise loftily opportune Out up and together came sudden to Sunday rite The one solemnly off to correct plenilune

I encourage you to generate a few more to test as you write your solution. I recommend setting `chance = 1.0` for one `Standard` test.
**Update (Mar 17, 2019):** I fixed a bug with the test case generator where digits `0n` would sometimes combine to become just `n`, dropping the zero. I moved the bugged "Standard" test case to be a test case for "Incorrect", and then I generated a new one for "Standard".

Thanks to *@KirillL.* for bringing to my attention that the input as a list of strings is allowed, saving 2 bytes by removing the *split on spaces*.
Takes the list of words as first input, and the PI-digits joined together to a single string as second input. Outputs `0` for incorrect; `1` for Basic; `2` for Standard.

J # Join everything together
Å? # Check if the (implicit) PI-input starts with this (1/0 for truthy/falsey)
®à # Push the list from the register again, and pop and push its maximum
g # Get the length of this maximum
* # And multiply it with the result from the check
# (after which the result is output implicitly)

Anonymous code block that takes input curried, like `f(pi)(list)` and returns `2` for Basic, `1` for Standard and `0` for invalid.
### Explanation:
```
->\p{ } # Anonymous code block taking pi
{ }o* # Returning a code block
>>.chars # That converts words to the length of each word
# Check if Basic if all numbers are below 11
.comb( ) # Match
/1<(0 # Only the 0s of 10s
|\d/ # and all other digits
Z==p # Zip equal each digit with pi
[*] # Are all digits equal?
(1+?(11>.all))* # And multiply by 2 if all digits are below 11, else 1
```
[Answer]
# JavaScript (ES6), 74 bytes

"Ruby – Try It Online")
Takes an array of words and a string of \$\pi\$ digits as input, returns:
Incorrect = `nil`, Standard = `false`, Basic = `true`
[Answer]
# [Kotlin](https://kotlinlang.org), 101 bytes
```
{p,s->s.split(" ").map {it.length}.let{if(!p.startsWith(it.joinToString(""))null else it.max()!!>10}}
```
Returns `null` if it's Incorrect pilish, `false` if it's Basic, and `true` if Standard.

[Question]
[
I guess I'm not the only one who have seen this kind of image on Facebook (and other sites).
[](https://i.stack.imgur.com/vgvsh.png)
The picture above was posted 16 days ago, and has accumulated 51 k comments. Some answers: 0, 4, 8, 48, 88, 120, 124 and so on.
# Challenge:
The mathematics in the question doesn't make sense1, so we can't find the correct answer by looking at the equation (or whatever you'd call that mess of numbers and operators). However, there's a very large number of people who have answered, and 10% of those people are right!
Let's find the right answer!
---
Take an integer, percent, decimal value in `0-1`, or fraction `N` representing how many percent of the test group who failed the question (or optionally how many answered correctly), and a list of numbers representing the answers people post.
Find the number that `100-N` percent of the test group answered and output it. If there are more than one answer that matches this criterion, then you must output all of them.
If there are no answers that are represented `100-N` percent of the time then you must output the number that's closest (measured in number of answers from `100-N`).
To make the input rules for `N` clear: If 90 % fails, then you may input `90`, `10`, `0.9` or `0.1`. You must specify which one you choose. You may assume that the percentage numbers are integers.
---
### Test cases:
In the test cases below, `N` is the percentage that failed the test. You may choose to input using any of the allowed input methods.
```
N: 90 (meaning 90 % will fail and 10 % answer correctly)
List: 3 1 5 6 2 1 3 3 2 6
Output: 5 (because 90 % of the answers weren't 5)
---
N: 50 (50 % will answer correctly)
List: 3 6 1 6
Output: 6 (because 50 % of the answers weren't 6)
---
N: 69 (31 % will answer correctly)
List: 1 9 4 2 1 9 4 3 5 1 2 5 2 4 4 5 2 1 6 4 4 3
Output: 4 (because 31% of 22 is 6.82. There are 6 fours, which is the
closest to 6.82)
---
N = 10 (90 % will answer correctly)
List: 1 2 3 4 5 6 7 8 9 10
Output: 1 2 3 4 5 6 7 8 9 10 (because 9/10 will answer correctly. All numbers
have been answered the same number of times, thus
all are equally likely to be correct.
---
N: 90
List: 1 1 1
Output: 1
```

Takes `N` as a number between `0` and `1`, and `A` as a vector (sometimes taken from STDIN in the TIO link so I don't have to turn them to R vectors). Returns a list of strings, as allowed by the [OP](https://codegolf.stackexchange.com/questions/144240/90-fail-this-challenge/144300#comment353681_144240).
```
function(N,A){
x <- table(A) # count occurrences of each value in A
pct <- 1 - x/sum(x) # compute percentages different from each value
y <- abs(pct - N) # find distances from N
idx <- y!=min(y) # find the indices of the minimum/minima
names(x)[idx] # return the names of the table (strings)
}

Takes input as `(a, r)` where ***a*** is the list of answers and ***r*** is the expected success ratio in **[0...1]**. Returns a **[`Set`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Set)**.
```

[Question]
[
Your geologist buddy nearly kicked down your office door as he burst in, eyes wide in excitement, and asked you to come with him to a site he just discovered. On the way he explains that he thinks he literally just struck gold. Only problem is, it's buried deep underground in a cavern with a very unstable roof. It's too dangerous to go spelunking, so he wants you to program one of his cave exploring robots to collect as much gold as it can before he pulls it back up. He also mentions that he's probed the cavern and found some wildlife that could be harmful to the robots, and also that he'd dropped some equipment down there that might still be useable. Each robot is equipped with two arms and a range of sensors. When you arrive at the scene, he tells you he's planning on recruiting more coders, and whoever does the best job will be rewarded.
Now, down to the nitty-gritty. The sensors pass information to your program as ASCII characters. Here's a list of what each character means and descriptions for anything the bot might encounter in the cave:
```
Code Name/Description
Y Your bot
You do things
@ Other bots
They do other things
- Ground
This doesn't do things
C Centipede
These will bite you and leave a poison effect
The bite will cost 1 health
The poison effect will last for 3 turns, costing 2 health each turn
B Bats
If bats end up in the same space you are, your bot runs in a random direction during its turn rather than what you told it to do
L Lion (because reasons)
Lions deal heavy damage, 10 health, each time they attack
F Food
Eating this will give you 5 health
Can only be used once
W Water
Drinking this will cure poison effects early
Can only be used once
R Revealer
This will increase the range of your visibility to an 11x11 grid
The extra range will only be 75% correct, but the original range won't be effected
K Knife
You do twice as much damage to other bots if you have a knife
G Gold
The whole reason you're doing this in the first place
N Nurse Nina
She mend you good
Restores your health by 10 while you occupy the same space as her
} Boulder
You can't walk over boulders, and neither can anything else
P Pit
If you fall in a pit, you will be stuck for 3 turns
```
The size of the cavern grows based on how many bots are participating. It starts as a 30x30, and it gets an extra 10x10 for every bot. So 2 bots will explore a 50x50 cavern.
Bots start with 20 health, but they don't have a maximum limit on health.
**Input:**
You'll receive input through STDIN in the following format:
```
20,5,10,1,0,True,False <-health, number gold pieces, number of turns your bot has lasted, number of until the poison wears off, number of turns until you are no longer stuck in a pit, if you have a revealer, if you have a knife
-----
-G}--
--Y-L
-C---
---B-
```
The first line contains information about your bot, and the rest is the grid that your bot can see. If your bot is against one of the 4 walls of the cavern, you will get a grid that looks more like this (in the case of being all the way to the West):
```
---
}--
Y--
---
---
```
The cavern does not wrap around, and neither does your vision. The walls of the cavern are not marked, the only indication your bot receives that it is nearing a wall is its view being diminished. With the Revealer, you might get something like this:
```
--------C--
LW--------B
---K-N-----
--------BR-
-F---------
--B--Y---@N
-W@---F----
------K-F--
----@-}----
R@---G}--}-
--------G-R
```
**Output:**
You get two moves per turn, which you output in the following format:
```
MNNANW <- Moves are groups of 3 characters representing the action and the direction
```
Possible actions are the following:
```
M Move - Move your bot in the specified direction
A Attack - Attack the square in the specified direction
H Hold - Do nothing
```
Possible directions are the following:
```
NN - North (up)
NE - Northeast (up-right)
EE - East (right)
SE - Southeast (down-right)
SS - South
SW - Southwest
WW - West
NW - Northwest
```
The moves are applied from left to right.
**Turns:**
Turns progress in the following fashion:
1. Poison effects are applied to any player who has been poisoned
2. Non-bots move and attack
2a. Lions, Centipedes, and Bats move randomly
2b. Lions and Centipedes will attack everything that is directly adjacent to it (including diagonally)
2c. The bat effect will only be applied to a bot if it is on the same space as the bat
2d. Nurse Nina will stay in a location for 3 turns, and then jump to a random location.
3. Bots move
3a. If your bot gives invalid output, it won't move
3b. Your bot will try to get as close to the space designated by the output as possible (see the note at the bottom for more detail)
3c. One attack to a Centipede, Lion, or Bat will kill it
3d. Attacking another bot without a knife will do 5 damage, and 10 with a knife
**Rules:**
1. Stick to common languages that can be run on OS X or Linux.
2. You can optionally write up to and not exceeding 1kb data to a file
**Scoring:**
Bots will only be in the cavern until only one remains, or until 50 turns have gone by, whichever comes first.
Your bot will be judged on the sum of the number of gold coins it collected and how many turns it lasted.
Controller code can be downloaded for testing [here](https://drive.google.com/file/d/0B0S-KjeVoiwPVmZoOC1idG5FcDQ/view?usp=sharing) (make a folder called "bots" in the same directory that you download it to, and put your bot inside "bots") You'll need NumPy to run it. Feel free to dig through it, but you'll have to excuse the mess...
Here's some code for a random bot:
```
#!/usr/bin/python
import random as r
a = ['M','A','H']
d = ['NN','NE','EE','SE','SS','SW','WW','NW']
print(a[r.randint(0,2)]+d[r.randint(0,7)]+a[r.randint(0,2)]+d[r.randint(0,7)])
```
\*\*\*\*Your bot will always move in the general direction your output specifies, but if it is obstructed by a rock or a wall, the exact direction depends on the circumstance. For instance, if your bot is against a wall like so:
```
---
}--
Y--
---
---
```
and your output is
```
MNWMSW
```
your bot will move one space down. It couldn't move North or West, so that move had no effect. It could move South (and did) but couldn't move West. However, if your bot tried to move Northeast, it would go directly to that space (diagonal movement is diagonal, not procedural)
**Leaderboard**
These are the average scores of 4 games.
```

# Coward, python3
A coward always runs from potential threats.
However, if he feels super strong, he will suddenly run amok
and stab everything near him.
The problem with the current implementation is that move commands are issued without knowledge whether it is the first or the second move.

Let \$n > 0\$. Let \$X = 1, 2,...,n\$ and \$Y = n+1, n+2, ..., 2n\$. Define \$a(n)\$ as the number of permutations \$p\$ of \$Y\$ such that every element of \$X + p(Y)\$ is prime. For example:
```
n = 2
X = [1,2]
Y = [3,4]
p_0(Y) = [3,4] => X + p0(Y) = [4,6] => No
p_1(Y) = [4,3] => X + p1(Y) = [5,5] => Yes
a(2) = 1
```
In as few bytes as possible, write a program or function which produces this sequence ([A070897](https://oeis.org/A070897)), either as an infinite list on STDOUT, or in your interpreter of choice.
The output should start at \$n=1\$, and each entry should be on a newline and undecorated, i.e.:
```
1
1
1
1
2
...
```
## Examples
\$a(1)=1\$ because each list `[1]`, `[2]` has only 1 element
\$a(5)=2\$ because there are two permutations: `[(1,10),(2,9),(3,8),(4,7),(5,6)]` and `[(1,6),(2,9),(3,10),(4,7),(5,8)]`
## Rules
No built-in primality tests. No lookup table ;). No standard loopholes.

This is an infinite list version. If you run it using the [Java compiler](https://sourceforge.net/projects/cjam/), you will keep on getting result for increasing `n` on each line until the program crashes (if it does. Did not test).
For sanity, run the finite version [using this link](http://cjam.aditsu.net/#code=ri%7B)%3AXe!%7Bee%7B1bX%2B)_m!)%5C)%25%7D%2C!%7D%2C%2Cp%7D%2F&input=6). You can change the number in the input to see a longer list.
**How it works**:
```
0{ }h e# This acts as an infinite do-while loop here
)_ e# Starting from 0, increment the number and copy it
e# Lets call this number at each iteration as N
e! e# Get all possible permutations of the array 0..N-1
{ }, e# Filter the list of permutations based on this code block
ee e# Convert the permutation array into an [index value]
e# pair array. For ex. [5 2]ee gives [[0 5] [1 2]]
{ }, e# Pass each index value pair through this filter
1b1$+) e# Sum the index and value and add current N + 1 to it
e# At this point, we have something equivalent to
e# pairwise addition of [1 .. n] and [n .. 2n - 1]
_m!)\)% e# Now we do ((N - 1)! + 1)%N to see if N is prime
e# This is Wilson's theorem and will give 0 for primes
! e# Now we have a filtered index-value pairs which all
e# correspond to non-prime numbers. If the list is empty,
e# Then all numbers are prime. Thus we do a ! on empty list
e# to get truthy.
,p e# Take the total permutations where X + pN(Y) are all
e# primes and print the number to STDOUT immediately
e# We are left with the initial incremented N on stack
e# which is always non-zero, so the loop continues
e# infinitely

Your task is to build a vim script or provide a sequence of keystrokes that will operate on a single line of text with up to 140 printable ASCII characters (anywhere in a file, with the cursor starting anywhere in the line) and reverse every space-separated string in the sentence while keeping the strings in the same order.
For example, the input:
```
roF emos nosaer m'I gnisu a retcarahc-041 timil no siht noitseuq neve hguoht ti t'nseod evlovni .rettiwT RACECAR
```
should return:
```
For some reason I'm using a 140-character limit on this question even though it doesn't involve Twitter. RACECAR
```
The script with the fewest characters, or the sequence of the fewest keystrokes, to achieve this result is the winner.

Recursive macro, I assume that `Ctrl`-`r` counts as one keystroke.
The hardest part was to make sure the macro stays on the same line and does not destroy the rest of the file.

I know this question is very old, but I love vimgolf so I couldn't *not* post an answer on one of the few vim-specific challenges on the site. Plus this solution is tied with Orlp's.
Just like Orlp said, the hardest part was making sure that the rest of the buffer was unmodified. If it weren't for that restriction, we could simply do:
```
:s/ /\r/g
!{rev
V}J
```
(19 keystrokes) but we need a little bit more to keep it buffer-safe. This assumes a unix environment.

Your task is to write a program in x86 machine language (any version you like) that will run through as many instructions as possible and then halt, using a maximum of 32 bytes of code and starting with zeroed-out registers.
You can assume anything about the random-access memory you like, as long as it's in a usable format for the x86 machine.
[Answer]
## 2524224 instructions
My program:
```
_start:
mov bl, _end
stc
iloop: adc [bx], al
inc bx
jnz iloop
jnc _start
a32
loop _start
hlt
_end:
```
(Technical note: this is written for nasm. The `a32` is nasm's syntax for the alternate address-size prefix byte. For masm, you would replace the `a32` with `defb 0x67`.)
For clarity, here's the listing output:
```
1 _start:
2 0000 B310 mov bl, _end
3 0002 F9 stc
4 0003 1007 iloop: adc [bx], al
5 0005 43 inc bx
6 0006 75F9 jnz iloop
7 0008 73F4 jnc _start
8 000A 67 a32
9 000B E2F1 loop _start
10 000D F4 hlt
11 _end:
```
The program assumes that the processor is in real mode, and that the program is located at the bottom of a 64k segment of memory which is otherwise initialized to all-bits-zero. Its design is simple: treat the memory as a single giant unsigned integer, and increment it through all possible values, until it rolls back around to all-zeroes. Repeat this 232 times. Then halt.
The innermost loop (lines 4‒6) is responsible for incrementing the huge integer. Each iteration adds zero or one to a single byte, depending on whether there was a carry out of the previous byte. Note that every byte in the huge integer is accessed, whether or not it has changed, so this loop always iterates 216 - 14 times.
By the way, in case you were wondering, this code illustrates the reason why the x86 `inc`/`dec` instructions don't affect the carry flag: just to simplify this sort of multi-byte carry pattern. (This pattern came up more often back in the days of 8-bit microprocessors, when the original 8080 instruction set was defined.)
Line 7 causes the incrementing process to repeat until a one is carried out of the last byte, indicating that the huge integer has been reset to all-bits-zero. This takes a long time.
Lines 8‒9 mark the outermost loop, and causes this process to repeat 232 times, until the `ecx` register rolls around to zero. This is effectively equivalent to adding another 32 bits to the giant integer.
It would be possible to add another outer loop and do this again using (say) the `edx` register, and then maybe using `esi` and `edi` for even more repetitions. However, it's not worth doing. The instructions to increment and loop require four bytes. Those four bytes are taken away from the giant integer. So we lose 32 bits on the RAM counter, just to add 32 bits via a register: it ends up being a wash. The only reason `ecx` is an exception is that it has a specialized `loop` instruction that fits into only three bytes. Thus the program trades 24 bits for 32, a tiny but still positive gain of 8 bits.
It's not too hard to directly calculate the number of instructions that the program executes before it halts. However, there's a much simpler way to estimate this number. The program modifies all of its memory, less the 14 bytes that contain the program, and the `bx` and `ecx` registers. This adds up to 216 - 14 + 2 + 4 = 65528 bytes, for a total of 524224 bits. The shortcut involves realizing that, in the process of running, every single possible pattern of 524224 bits appears exactly once. For the RAM and the `ecx` register this is easy to see, since the program increments through every single value. For `bx` this is a little less obvious, since it's being changed at the same time as the value in memory is being updated. However, one can show that, given the program's structure, if a complete bit pattern were to actually appear twice, then the program would have to be in an infinite loop. Since this is not the case, each bit pattern must ultimately be visited only once. (The complete proof is left as an exercise to the reader, naturally.)
Since every possible bit pattern appears in the course of the program, the program must execute at least 2524224 instructions, which is approximately equal to 1.4 × 10157807. (The acutal number is very slightly higher, because of the jump instructions, but the difference at this magnitude is negligible.)
Obviously, this could be significantly improved by using more than 64k of RAM. I'm holding off on the next version of the code until I figure out exactly how much RAM can be accessed.

Similar to breadbox's solution, but there's no reason to stop at 16 bits of address. My code uses x86-64 and assumes we have 2^64 bytes of memory and we use all but the memory holding the code as a giant counter.

[Question]

Given two strings containing only `0` and `1`, decide the probability that first appears earlier as a consecutive substring in an infinite random 0/1 stream.
You can assume that neither string is suffix of the other string, so `01, 1`, `00, 0` are invalid. (\*)
IO format flexible. Your answer should be precise given ideal floating point numbers, so [sampling](https://tio.run/##VcgxDgIhEADA/j7CrkQCFhaH6AusrckBHuZkDUsMhX/HWDrlPPzb81Lzq@0LhThGct2du4ol8C23FYQ2RuDFzH@nf6fnBF3C1bdVVV8CPQF3h49GnBJVYJedtvlk4tFKmZGlSyAE2mmhwrRFtdEdGMf4Ag) is likely not a good idea.
Shortest code wins.
# Note
* I'd like to see how much longer code without assumption `(*)`, allowing collision in a sequence but won't happen (due to fact that one string would appear earlier) or even just no extra rule(In which case `f(a,b)+f(b,a)!=1`). Therefore, you may also provide version(s) that do so, even if longer, if convenient.
# Test cases
```
0, 1 => 50%
00, 1 => 25%
10, 00 => 75%
0, 01 => 100%
011, 001 => 1/3
00, 110 => 1/2 (Example with different length input but result half)
000, 101 => 5/12 (Examples provided by Bubbler)
000, 011 => 2/5
111, 1001 => 4/7
111, 0011 => 5/12 (Suggested by Neil, longer string would likely come earlier)
(Following not required)
11, 1 => 0%
1, 11 => 100%
10, 10 => 100% (0% if you choose strict early)
01, 1 => 50% (0%)
1, 01 => 100% (50%)

Outputs the ratio as a fraction but not necessarily in lowest terms. Technically works for all edge cases although two identical inputs outputs `0/0`. Explanation: For the Cartesian product of the two inputs with itself, calculates which suffixes of one are prefixes of the other, then interprets that in base `2`; this is negated when the strings are compared against each other. The final denominator is simply the sum of all four values; the numerator is the sum of two of them. Example for `111` and `0011`:
```
Suffixes of 111: 111 11 1
Are they prefixes of 111? 1 1 1 = 7
Are they prefixes of 0011? 0 0 0 = -0
Suffixes of 0011: 0011 011 11 1
Are they prefixes of 111? 0 0 1 1 = -3
Are they prefixes of 0011? 1 0 0 0 = 8
Numerator = 8 - 3 = 5
Denominator = 8 - 3 + 7 - 0 = 12
```
Note that the values `7` and `8` are also half the indices at which you would expect to find `111` and `0011` respectively, which leads to the paradox that although you would expect to see `0011` first, the expected position of `111` is before that of `0011`.

This challenge is from a game, [Keep Talking And Nobody Explodes](https://keeptalkinggame.com/).
*This is like one of those toys you played with as a kid where you have to match the
pattern that appears, except this one is a knockoff that was probably purchased at
a dollar store.* – From the [manual](https://www.bombmanual.com/print/KeepTalkingAndNobodyExplodes-BombDefusalManual-v1.pdf)
# Objective
The **Simon Says** module consists of 4 colored buttons: **R**ed, **B**lue, **G**reen, and **Y**ellow. Given a sequence of button flashes and a sequence of button presses, decide whether it would disarm the module.
In the original game, the module consists of multiple stages, but in this challenge, only one stage will be considered.
# How To Disarm
* The buttons will flash in a sequence. These buttons shall be mapped accordingly to the chart below, and shall be pressed.
* You may press the wrong button in cost of a **strike**. Then the mapping will change. Only up to 2 strikes are tolerable because a 3rd strike will detonate the bomb.
* You must not press buttons anymore after the module is disarmed.
The chart:
```
Strikes\Flash Red Blue Green Yellow
0 Blue Red Yellow Green
1 Yellow Green Blue Red
2 Green Red Yellow Blue
```
(This chart is for a bomb whose serial number has a vowel. It is assumed for the purpose of this code-golf challange.)
# I/O format
The input shall be two strings consisting of `R`, `B`, `G`, and `Y`, indicating the colors. Case sensitive.
Though in the game, a stage consists of up to 5 flashes, in this challenge, there may be an arbitrary nonzero number of flashes.
An input not fitting to this format falls in *don't care* situation.
The output format is flexible.
# Examples
Let's say the button flash sequence is `GRYBB`. The followings are examples of button press sequences:
## Truthy
* `YBGRR`
* `RBYRGG` (in cost of 1 strike)
* `YBGRBG` (in cost of 1 strike)
* `YBGBGRR` (in cost of 2 strikes)
## Falsy
* `YBG` (The module isn't disarmed yet)
* `RRR` (The 3rd strike detonated the bomb)
* `YBGRRB` (You cannot press buttons anymore after the module is disarmed)
* `RRRY` (You cannot press buttons after the bomb detonates)

## Background
This is Post's lattice:
[](https://i.stack.imgur.com/flzRU.png)
Credit: [EmilJ](https://commons.wikimedia.org/wiki/File:Post-lattice.svg)
It denotes the lattice of all clones on a two-element set `{0, 1}`, ordered by inclusion (from Wikipedia). That can be a bit of a mouthful so lets look at a concrete example. `MP` (located near the top) is a set that contains all boolean circuits that can be made with `and` and `or`. `DM` (a bit lower) is the set of all boolean circuits that can be made with the majority gate. The majority gate (`maj`) takes three inputs and returns true iff at least two of the inputs are true. This is a hasse diagram ordered by inclusion, which means that since `DM` is below `M` and you can reach it by a sequence of nodes at decreasing heights, `DM` is a (strict) subset of `M`. This means that every circuit that can be made with `maj` can be replicated using `∧` and `∨`.
I've colored the nodes according to the computational complexity of the boolean satisfiability problem restricted to that set of circuits. Green means `O(1)`. This means that either the set is always satisfiable or it contains a finite amount of elements. Yellow is linear time. Red is NP-complete.
As you can see, \$T\_0^\infty\$ is the smallest NP-complete set. It is generated by `↛` which is the negation of implication. In other words, it is the set of all formulas consisting of `↛` and brackets.
## Task
Your task is to solve a instance of nonimplication-SAT. That is, you are given a boolean formula consisting of variables and the operator `↛` which has the following truth table:
```
a b a↛b
0 0 0
0 1 0
1 0 1
1 1 0
```
Your program has to decide whether there is an assignment to the variables which satisfies the formula. That is, the value of the formula is `1`.
## Test cases
```
a↛a: UNSAT
a↛b: SAT
(a↛b)↛b: SAT
((a↛(c↛a))↛(b↛(a↛b)))↛(a↛(b↛c)): UNSAT
```
## Rules
This is a decision problem so you should have two distinct output values for SAT and UNSAT. Use a reasonable input format. For example:
```
"(a↛(b↛c))↛(b↛a)"
[[0,[1,2]],[1,0]]
"↛↛a↛bc↛ba"
```
Make sure that the format you choose can handle an unlimited amount of variables. For strings just the letters a to z are not enough as there is only a finite amount of them.
Bonus points if your code runs in polynomial time :p

# Universal Command Sequence
## Definition
An \$n\$-maze is a \$n\times n\$ chessboard which has "walls" on some edges, and a "king" on the board that can move to the 4 adjacent cells, which cannot pass through any walls. Starting from any cell the king should be able to reach every cell on the board.
A command sequence is an array consisting of 4 distinct types of element (for example `[1,2,3,4,1,4,2,3,1,...]`). Each type of element means a direction of the movement of the king. A command sequence can be "applied to" a maze, if the king can traverse every cell on the board by following the command sequence. For example a command sequence `[up,right,down]` can be applied to a 2-maze that has no walls and the king is placed at the botton-left cell. If the king is going to pass through a wall or go outside the board, the command will be skipped.
## Challenge
For a given positive integer \$n\$, output a command sequence that can be applied to any \$n\$-maze. The existence of this sequence can be proved mathematically.See 1998 All-Russian Math Olympiad, Grade level 9, Day 1, Problem 4.
### Input
A positive integer `n`. You can assume that `n>1`.
### Output
An array consisting of 4 distince types of elements.

We could construct a universal sequence of length \$2^{2n(n-1)} ⋅ n^2 ⋅ (2n^2 - 2) < 5^{n^2}\$. Start with the empty sequence; then for each of the at most \$2^{2n(n-1)}\$ mazes and \$n^2\$ possible starts, imagine following all the previously appended commands to get a new location, and append \$2n^2 - 2\$ more commands representing a complete traversal of that maze from that new location.
But, since we know we could construct it, we don’t have to actually do it. Instead, just concatenate all length \$5^{n^2}\$ sequences of \$1, 2, 3, 4\$. Since we just proved at least one of those sequences is universal, so is their concatenation.

The definitions used in [Lv1](https://codegolf.stackexchange.com/q/236182/78410) will be reused here. I've done some improvements:
* Now it starts with `import tactic`, which means you can freely use powerful mathlib tactics.
* I noticed that I can define the general list notation `[a, b, ..., z]` without problems.
```
import tactic
universe u
variables {A : Type u}
namespace mylist
inductive list (T : Type u) : Type u
| nil : list
| cons : T ‚Üí list ‚Üí list
infixr ` :: `:67 := list.cons
notation `[]` := list.nil
notation `[` l:(foldr `, ` (h t, list.cons h t) list.nil `]`) := l
def append : list A ‚Üí list A ‚Üí list A
| [] t := t
| (h :: s) t := h :: (append s t)
instance : has_append (list A) := ‚ü®@append A‚ü©
@[simp] lemma nil_append (s : list A) : [] ++ s = s := rfl
@[simp] lemma cons_append (x : A) (s t : list A) : (x :: s) ++ t = x :: (s ++ t) := rfl
@[simp] def rev : list A ‚Üí list A
| [] := []
| (h :: t) := rev t ++ [h]
```
Now, here's a new definition we will use from now on: a membership relationship between an element and a list. It is defined recursively using two cases: A value `x` is in a list `l` if
* `x` is the head of `l`, or
* `x` is in the tail of `l`.
```
inductive is_in : A ‚Üí list A ‚Üí Prop
| in_hd {x : A} {l : list A} : is_in x (x :: l)
| in_tl {x y : A} {l : list A} : is_in x l ‚Üí is_in x (y :: l)
open is_in
```
Now your task is to prove the following two statements: (think of these as parts of a chapter, sharing a few lemmas)
* `is_in_append`: `x` appears in `l1 ++ l2` if and only if `x` appears in `l1` or `x` appears in `l2`.
* `is_in_rev`: if `x` appears in `l`, `x` appears in `rev l`.
```
theorem is_in_append : ∀ (x : A) (l1 l2 : list A), is_in x (l1 ++ l2) ↔ is_in x l1 \/ is_in x l2 := sorry
theorem is_in_rev : ∀ (x : A) (l : list A), is_in x l → is_in x (rev l) := sorry
```

### Tips for beginners
The new beast called "inductive Prop" is a particularly hard concept to grasp. Simply put, a value of `is_in x l` contains a concrete proof that `x` appears in `l`. It is an unknown value, but we can still reason about it:
* Consider all the possible paths `is_in x l` could have been constructed (i.e. proven). This is done with `cases` tactic. When used on a hypothesis of `is_in x l`, it generates two subgoals, one assuming `in_hd` and the other assuming `in_tl`.
+ If you use `cases` on `is_in x []`, there is no way it could have been constructed (since both possibilities result in a cons), the goal is immediately closed by contradiction.
* Apply induction on the proof. It works just like induction on a nat or a list: to prove a theorem in the form of `∀ (x:A) (l:list A), is_in x l → some_prop`, you can prove it by induction on `is_in x l` and prove the "base case" `is_in x (x::l)` and "inductive case" `(is_in x l → some_prop) → is_in x (y::l) → some_prop`.
It takes some practice to see which argument (an inductive data or an inductive prop - in this challenge, `list` or `is_in`) works best with induction for a given statement. You can start by proving parts of the main statement separately as lemmas:

>
> ```
> lemma is_in_append_l : ∀ (x : A) (l l2 : list A), is_in x l → is_in x (l ++ l2) := sorry
> lemma is_in_append_r : ∀ (x : A) (l l2 : list A), is_in x l → is_in x (l2 ++ l) := sorry
> ```
> (Hint: One works best by induction on `l2`, and the other works best on `is_in x l`.)

`P` and `Q` are the desired theorems. I reuse the `~` notation (which is normally for the `list.perm` relation) to mean the `is_in` relation, which lets us save a lot of spaces in lemma statements.
I was going for "readable" and fast-to-typecheck (Anders isn't kidding about their solution being slow!). `D` is a definition lemma for `is_in` (mathlib calls the reversed version of it [`list.mem_cons_iff`](https://leanprover-community.github.io/mathlib_docs/init/data/list/lemmas.html#list.mem_cons_iff); I had to reverse it to trick Lean into disambiguating `::` correctly). The `E` lemma uses the equation compiler to automatically construct a proof (mathlib calls it [`list.not_mem_nil`](https://leanprover-community.github.io/mathlib_docs/init/data/list/lemmas.html#list.not_mem_nil)).
Some of these tricks can shorten Anders's first solution to 217 bytes:
```
infix`~`:=is_in
attribute[simp]in_hd in_tl
def P(x:A)(l m):x~l++m‚Üîx~l\/x~m:=by induction l;split;intro;repeat{finish<|>cases
·æ∞<|>cases l_ih.1 ·æ∞_·æ∞}def R(x:A)(l)(i:x~l):x~rev l:=by induction i;simp[P];left;tauto
```
---
I want to mention that `is_in` might more conventionally be given as a recursive definition:
```
def is_in (x : A) : Π (l : list A), Prop
| [] := false
| (y::ys) := x = y ‚à® is_in ys
```
Given this, there is a 150 byte solution:
```
infix`~`:=is_in
def P(x:A)(l m):x~l++m‚Üîx~l\/x~m:=by
induction l;split;simp!;intro;safe
def Q(x:A)(l)(i:x~l):x~rev l:=by induction l;simp![P]at*;safe

Inspired by [This answer to a Puzzling question](https://puzzling.stackexchange.com/a/97195/42642)
**Background - exponentiation by squaring**
*If you don't want to read the background, or don't understand it, there's a worked example in Java, linked at the bottom of the post.*
\$a^{2^{x+1}} = a^{2^{x}} \* a^{2^{x}}\$
Therefore to find \$a^b\$ (where \$a\$ and \$b\$ are base-10 numbers), you can use the following steps:
(using the example: \$a^b = 3^{2020} = 6.0944502154628860109199404161593e+963\$)
1. Convert \$b\$ to binary (\$2020\$ -> \$11111100100\$)
2. For each \$1\$ in the binary (\$n\$), calculate \$a^n\$, by starting at \$a^1\$ and repeatedly squaring to get \$a^2\$, \$a^4\$, etc... and keeping only those numbers we need (\$3^1 = 3\$, \$3^2 = 9\$, squared gives \$3^4 = 81\$, squared gives \$3^8 = 6561\$, squared gives \$3^{16} = 43046721\$, squared gives \$3^{32} = 1853020188851841\$, etc. We just keep those numbers where the binary mask is a 1.)
3. Multiply all the kept answers from step 2 where the binary mask is a \$1\$ (\$81\*1853020188851841\*...\$).
4. The first non-zero digit is therefore \$6\$.
The problem with this method though, even though it is easier for humans than calculating such a large exponent straight-off, is that you still have to square some pretty large numbers.
***In Theory, though, we can approximate!***
According to the link at the start of the question, you can approximate by just considering the first \$n\$ digits (rounded) at each stage in step 2 above - with larger \$n\$ giving a lower margin of error.
**For example**, if \$n=4\$, then you get\* \$3^2=9,^2=81,^2=6561,^2\approx4305,^2\approx1853,^2\approx3434,^2\approx1179,^2\approx1390,^2\approx1932,^2\approx3733\$.
note that the numbers here have been rounded\*, rather than just truncated - e.g. 6561 \* 6561 = 43046721 - which has been rounded to 430**5** rather than 430**4**.
Keeping \$3733,1932,1390,1179,3434,1853,81\$ from the bitmask we can then do \$3733\*1932\*1390\*1179\*3434\*1853\*81= 6091923575465178358320\$, so the first digit is \$6\$, as we would expect.
This is not only easier in our heads, but it gives us the same first digit! Much simpler!
However, if we only consider the first \$3\$ digits when we double, instead of the first \$4\$, we get \$353\*188\*137\*117\*342\*185\*81 = 5451573062187720\$, which gives us a first digit of \$5\$ instead of \$6\$ - that's why it's only approximately accurate!
---
**The Challenge** is to find the first digit of \$a^b\$, where only the first \$n\$ digits, rounded, are considered each time we square. You don't have to use exponentiation by squaring in your program, if you can get the correct answers by another method.
**Inputs**
Three positive Integers (greater than \$0\$), up to an arbitrary maximum (your program should work in theory for all possible Integers) - the base \$a\$, the exponent \$b\$ and the approximation length \$n\$
**Output**
a single digit or character in the range [1..9]
**Some Worked Examples**
`3,2020,3` -> `5` (see worked example in background above)
`3,2020,4` -> `6` (see worked example in background above)
`2,20,1` -> \$20\_{10} = 10100\_2. 2^1=2,^2=4,^2=16\approx2,^2=4,^2=16\approx2\$ which gives \$2^{16}\*2^4\approx2\*2\$ = `4`
`2,20,2` -> \$2^1=2,^2=4,^2=16,^2=256\approx26,^2=676\approx68\$ which gives \$68\*16 = 1088\$, first digit `1`
`2,20,3` -> \$2^1=2,^2=4,^2=16,^2=256,^2=65536\approx655\$ which gives \$655\*16 = 10480\$, first digit `1`
`2,20,4` -> \$6554\*16 = 104864\$, first digit `1`
`2,20,5 or above` -> \$65536\*16 = 1048576\$, first digit `1`
`15,127,5` -> `15,225,50625,25629...,65685...,43145...,18615...` -> `231009687490539279462890625` -> `2`

\*to clarify what I mean by rounding, any number less than \$x.5\$ should round down to \$x\$. Any number greater than \$x.5\$ should round up to \$x+1\$. The boundary (\$x.5\$) can go either way, depending on your language.

Reads 3 integers from `STDIN`, and print out the first digit approximation.
**Rounding**: `x.5` is always rounded down. This causes the test case `(5, 54, 2)` to gives the wrong result.
**Explanation**:
This part is the regular exponentiation by squaring:
```
while b:s*=a**(b%2);a*=a;b/=2
```
This is the rounding part:
```
a=int(`a`[:n])+(`a`[n:]>"5")
```
which takes the first `n` digits of `a`, and adds an extra 1 if the remaining part is more than `5`.

### How?
At each iteration:
* We compute \$a^2\$ with \$n\$ significant digits thanks to the `.toPrecision()` method. This gives a string, which may be in scientific notation.
Example for \$a=1023\$:
```
(1046529).toPrecision(4) ~> "1.047e+6"
```
* we coerce this result to a number and immediately back to a string:
```
+(1046529).toPrecision(4)+'' ~> "1047000"
```
* we keep the \$n\$ first characters to get the new value of \$a\$:
```
(+(1046529).toPrecision(4)+'').slice(0,4) ~> "1047"
```
The highest value of \$n\$ that can be supported is \$10\$ because:
$$(10^{10}-1)^2=99999999980000000000$$
which is already greater than `Number.MAX_SAFE_INTEGER`, but sill coerced to its standard decimal representation `"99999999980000000000"`.
For \$n>10\$, the result is always stringified in scientific notation (e.g. `9.9999999998e+21`) and the algorithm doesn't work anymore.

My `(5, 54, 2)` test case gives a different result; I suspect it is because of how Python rounds `62.5` vs how the reference implementation rounds `62.5`.

For more MtG-goodness: [Magic: The Gathering Combat with Abilities](https://codegolf.stackexchange.com/questions/171158/magic-the-gathering-combat-with-abilities?rq=1)
# Premise:
In Magic: the Gathering, you cast spells by paying their mana cost by tapping lands for the required amount. These lands can produce one of the five colors which are:
* White (W)
* Blue (U)
* Black (B)
* Red (R)
* Green (G)
The cost is made up of two parts: a number which is the generic mana requirement, and a series of symbols representing the colored mana requirement. The number is the generic mana cost and can use any color of mana to satisfy it, e.g. `(3)` can be paid with `WGG`. The symbols are a 1:1 requirement of a specific color. e.g. `WWUBR` would require 2 white mana, 1 blue, 1 black and 1 red. **The Generic part will always come before the Colored part.** As a reminder, `(0)` is a valid cost and must be handled.
You can have costs that are entirely generic, or entirely colored, or both. For example, the following card has a cost of 4BB and is be paid with 4 of whatever colored mana and 2 black mana:
[](https://i.stack.imgur.com/N3qqD.png)
Lands in this challenge will each produce one mana. However, we will consider lands that can produce multiple colors but still only yield 1 mana. E.g. `G` will produce a green mana, `WG` can produce either 1 white or 1 green.
# Input:
You will be given two inputs, a card's cost and a list of lands.
The card's cost can either be a string, or a tuple containing a number and a string for the colored part. If there's no generic part, you can pad the string/tuple with a 0.
The land list will be a list of strings where each one is what a given land can produce. This list can be empty (you have no lands). You can also take this as a list of ints using bit-mask logic but post your scheme if you do. Order is also up to you if it matters, otherwise it'll be assumed in `WUBRG` order.
```
#Example input formats
"4BB", ("WG","B","B") #
(4,"BB"), (7,3,3) #Both should return falsy
```
# Output:
A `truthy` value if you can successfully pay the cost given your lands and a `falsey` value if you cannot.
# Rules:
* You'll be guaranteed valid input
* Mana will be assumed to always be in "WUBRG" order. If you want a different order, state so in your answer.
* Colors will always be grouped in the cost, e.g. "WWUBBRG"
* Input will use either all Uppercase or all lowercase, your choice.
* You should be able to handle regex `127[WUBRG]{127}` and 254 lands.
* Standard loopholes forbidden

Convert the generic mana to unary. This uses repeated `_`s.
```
1,L`.*
```
Match all lines after the first, i.e. the list of lands. (This would normally match again at the very end of the input, but the lookbehind prevents that.)
```
(?<=(^|.*¶)+)
```
Capture the 1-indexed line number in `$#1`.
```
$
(?($#1)^|([_$&]))
```
Replace each land with a regex that captures costs matching that land or generic costs, but only once.
```
|'|
```
Join the resulting regexes with `|`s.
```
["^("]")*\n"
```
Wrap the regex in `^(` and `)*\n` (I can't seem to insert a `¶` here).
```
~
```
Count the number of matches of that regex on the current value.
Example: For the case of `1BB¶WB¶WB¶WG` the generated regex is:
```
^((?(2)^|([_WB]))|(?(3)^|([_WB]))|(?(4)^|([_WG])))*\n
```
which `_BB¶WB¶WB¶WG` matches as required.

Curried function. Takes input as `(@lands)($generic_cost, $colored_costs)` with an explicit 0 for generic cost. The basic idea is to introduce a new symbol `1` representing generic mana and use Perl 6 Bags (multisets) to check whether it's possible to obtain the required mana from lands.
### Explanation
```

1 x* # '1' for generic mana repeated times generic cost

We rely on the fact that all colors will be given in the same order in the cost and in the land list. First we tap the lands giving the required colored mana and after that just check that we still have enough lands to pay the colorless cost.

[Question]
[
We have a floating point number `r` between 0 and 1, and an integer `p`.
Find the fraction of integers with the smallest denominator, which approximates `r` with at least `p`-digit precision.
* Inputs: `r` (a floating point number) and `p` (integer).
* Outputs: `a` and `b` integers, where
+ `a/b` (as float) approximates `r` until `p` digits.
+ `b` is the possible smallest such positive integer.
For example:
* if `r=0.14159265358979` and `p=9`,
* then the result is `a=4687` and `b=33102`,
* because `4687/33102=0.1415926530119026`.
Any solution has to work in theory with arbitrary-precision types, but limitations caused by implementations' fixed-precision types do not matter.
Precision means the number of digits after "`0.`" in `r`. Thus, if `r=0.0123` and `p=3`, then `a/b` should start with `0.012`. If the first `p` digits of the fractional part of `r` are 0, undefined behavior is acceptable.
Win criteria:
* The algorithmically fastest algorithm wins. *Speed is measured in O(p).*
* If there are multiple fastest algorithms, then the shortest wins.
* My own answer is excluded from the set of the possible winners.
P.s. the math part is actually much easier as it seems, I suggest to read [this](https://math.stackexchange.com/q/2432123/111704) post.

I used the algorithm from <https://math.stackexchange.com/questions/2432123/how-to-find-the-fraction-of-integers-with-the-smallest-denominator-matching-an-i>.
At each step, the new interval is one half of the previous interval. Thus, the interval size is `2**-n`, where `n` is the current step. When `2**-n < 10**-p`, we are sure to have the right approximation. Yet if `n > 4*p` then `2**-n < 2**-(4*p) == 16**-p < 10**-p`. The conclusion is that the algorithm is `O(p)`.
**EDIT As pointed out by orlp in a comment, the claim above is false.**
In the worst case, `r = 1/10**p` (`r= 1-1/10**p` is similar), there will be `10**p` steps : `1/2, 1/3, 1/4, ...`. There is a better solution, but I don't have the time right now to fix this.

[Question]
[
First, a few definitions:
* Given `n` and `k`, consider the sorted list of [**multisets**](https://en.wikipedia.org/wiki/Multiset), where for each multiset we choose `k` numbers from `{0, 1, ..., n-1}` with repetitions.
For example, for `n=5` and `k=3`, we have:
>
> [(0, 0, 0), (0, 0, 1), (0, 0, 2), (0, 0, 3), (0, 0, 4), (0, 1, 1), (0, 1, 2), (0, 1, 3), (0, 1, 4), (0, 2, 2), (0, 2, 3), (0, 2, 4), (0, 3, 3), (0, 3, 4), (0, 4, 4), (1, 1, 1), (1, 1, 2), (1, 1, 3), (1, 1, 4), (1, 2, 2), (1, 2, 3), (1, 2, 4), (1, 3, 3), (1, 3, 4), (1, 4, 4), (2, 2, 2), (2, 2, 3), (2, 2, 4), (2, 3, 3), (2, 3, 4), (2, 4, 4), (3, 3, 3), (3, 3, 4), (3, 4, 4), (4, 4, 4)]
>
>
>
* A **part** is a list of multisets with the property that the size of the intersection of all multisets in the part is at least `k-1`. That is we take all the multisets and intersect them (using multiset intersection) all at once. As examples, `[(1, 2, 2), (1, 2, 3), (1, 2, 4)]` is a
part as its intersection is of size 2, but `[(1, 1, 3),(1, 2, 3),(1, 2, 4)]` is not, because its intersection is of size 1.
**Task**
Your code should take two arguments `n` and `k`. It should then greedily go through these multisets in sorted order and output the parts of the list. For the case `n=5, k=3`, the correct partitioning is:
```
(0, 0, 0), (0, 0, 1), (0, 0, 2), (0, 0, 3), (0, 0, 4)
(0, 1, 1), (0, 1, 2), (0, 1, 3), (0, 1, 4)
(0, 2, 2), (0, 2, 3), (0, 2, 4)
(0, 3, 3), (0, 3, 4)
(0, 4, 4)
(1, 1, 1), (1, 1, 2), (1, 1, 3), (1, 1, 4)
(1, 2, 2), (1, 2, 3), (1, 2, 4)
(1, 3, 3), (1, 3, 4)
(1, 4, 4)
(2, 2, 2), (2, 2, 3), (2, 2, 4)
(2, 3, 3), (2, 3, 4)
(2, 4, 4)
(3, 3, 3), (3, 3, 4)
(3, 4, 4), (4, 4, 4)
```
Here is another example for `n = 4, k = 4`.
```
(0, 0, 0, 0), (0, 0, 0, 1), (0, 0, 0, 2), (0, 0, 0, 3)
(0, 0, 1, 1), (0, 0, 1, 2), (0, 0, 1, 3)
(0, 0, 2, 2), (0, 0, 2, 3)
(0, 0, 3, 3)
(0, 1, 1, 1), (0, 1, 1, 2), (0, 1, 1, 3)
(0, 1, 2, 2), (0, 1, 2, 3)
(0, 1, 3, 3)
(0, 2, 2, 2), (0, 2, 2, 3)
(0, 2, 3, 3), (0, 3, 3, 3)
(1, 1, 1, 1), (1, 1, 1, 2), (1, 1, 1, 3)
(1, 1, 2, 2), (1, 1, 2, 3)
(1, 1, 3, 3)
(1, 2, 2, 2), (1, 2, 2, 3)
(1, 2, 3, 3), (1, 3, 3, 3)
(2, 2, 2, 2), (2, 2, 2, 3)
(2, 2, 3, 3), (2, 3, 3, 3)
(3, 3, 3, 3)
```
**Clarification of what greedy means:** For each multiset in turn we look to see if it can be added to the existing part. If it can we add it. If it can't we start a new part. We look at the multisets in sorted order as in the example given above.
**Output**
You can output the partitioning in any sensible format you like. However, multisets should be written horizontally on one line. That is an individual multiset should not be written vertically or spread over several lines. You can choose how you separate the representation of parts in the output.
**Assumptions**
We can assume that `n >= k > 0`.

end;
if(a)
fprintf('\n');
p=l(i,:);
end;
disp(l(i,:));
end;
```
**Explanation:**
First we find all the multisets with brute force:
```
l=unique(sort(nchoosek(repmat(0:n-1,1,k),k),2),'rows');
```
`repmat(0:n-1, 1, k)` repeats the vector of values from `0` to `n-1` `k` times.
`nchoosek(x, k)` returns a matrix containing all k-combinations of the repeated vector.
`sort(x, 2)` sorts all the k-combinations, and then `unique(x, 'rows')` removes all duplicates.
`p=zeros(0,k);` creates an empty matrix with `k` columns. We'll use it as a stack. On each iteration of the outernmost `for` loop, we first add the current multiset to said stack: `p=[p;l(i,:)];`.
Then we check if the intersection of all multisets in the stack is at least `k-1` long with the following code (we can't use MATLAB's `intersect` command to check for the intersections, because it returns a set, but we need a multiset):
```
a=0;
for j=1:size(p,1)
for m=1:size(p,1)
b=0;
for h=1:k
if(p(j,h)==p(m,h))
b=b+1;
end;
end;
if(b<k-1)
a=1;
end;
end;
end;
```
Now, if the intersection is long enough, `a == 0`, otherwise `a == 1`.
If the intersection isn't long enough, we print a newline and empty the stack:
```
if(a)
fprintf('\n');
p=l(i,:); % Only the current multiset will be left in the stack.
end;
```
Then we just print the current multiset:
```
disp(l(i,:));
```

### Explanation
*Disclaimer: this method seems to work (and it does in the test cases), but I don't have a proof that it always does*
Multisets are sorted, both internally (i.e. each multiset has non-decreasing entries) and externally (i.e. multiset *M* comes before multiset *N* if *M* precedes *N* lexicographically).
To compute the multiset intersection, the sorted multisets are arranged as rows of a matrix and consecutive differences are computed along each column. If all columns except at most one have all differences equal to zero, the multisets belong to the same part.
This test would give a false negative result for multisets like `(1,2,3)` and `(2,3,4)`: even if `2`, `3` are common entries, they would not be detected as such because they are in non-matching columns.
However, this doesn't seem to be a problem, at least in the test cases. It appears that a test between multisets like `1,2,3` and `2,3,4` never actually has to be done, because some intermediate multiset gave a negative result and so they already are in different parts. If this is indeed true, the reason no doubt has to do with the fact that the multisets are sorted.
I don't have a proof of this, though. It just seems to work.

[Question]
[
Write a program or function with the following functionality:
* The program/function first attempts to write the string `Hello, world!` to the standard output stream. (No other forms of output are acceptable for this challenge, as the focus is very much on the I/O rather than the trivial behaviour of the program itself.) Depending on whether it succeeded:
+ If it succeeded in outputting `Hello, world!`, the program/function exits without any further behaviour.
+ If it failed to produce the correct output due to an error, the program/function attempts to write the string `Error writing "Hello, world!"` to the standard error stream. (For the purposes of this challenge, you don't need error handling for the error handling itself.)
## Clarifications
* Your program/function will be run with no input (unless it's written in a language which absolutely requires input to work, in which case it will be run with the simplest possible input).
* When producing output, you may also produce a single trailing newline if you wish, but doing so is not mandatory.
* The definition of "error writing to standard output" that your program implements must treat at least the following cases as errors:
+ Standard output being nonexistent (i.e. `stdout` is a closed filehandle, no file descriptor 1 exists, or however those cases translate to the language and OS you're using);
+ Standard output referring to a file on a disk that has no free space left;
+ Standard output connecting to another program, which has already closed its end of the connection.and must treat at least the following cases as success (i.e. not an error):
+ Standard output connects to a terminal, and `Hello, world!` is displayed onscreen.
+ Standard output connects to a file, and `Hello, world!` is written into the file.You can choose the details of what counts as an output error, so long as it's consistent with the above rules.
* Your program/function should not crash upon encountering any of the error situations listed above. It's up to you what exit code you use.
* Your program/function should not describe the nature of the encountered error on the standard error stream; it should just print the string specified above. Extraneous output on standard error (e.g. compiler warnings) is only legal if it's produced unconditionally, regardless of whether an error is encountered or not.
* Your program only needs to work on one operating system (although it must be one on which the errors listed above make sense; I've tried to keep them general enough to work on most multitasking consumer operating systems, but weirder operating systems may well be excluded from this challenge). If your program is nonportable, list the assumptions it needs to run in the title of your submission.
* This task may not be possible in every language (not every language allows a program to handle output errors in a custom way). You'll have to pick a language where it is possible.
* Make sure that your program/function works! Don't just trust the documentation of library functions to do what they say they do. The error handling of simple output functions often turns out to be broken in practice, even if the functions claim to handle errors in theory.
## Test cases
Here's a way to simulate each of the error conditions above using `bash` on Linux (you don't have to use Linux, but it's likely the easiest system to test this on):
```
your_program_here >&- # nonexistent stdout
your_program_here > /dev/full # out of disk space
mkfifo test # note: change "test" to a filename that isn't in use
true < test &
your_program_here > test # connecting to a program that doesn't want input
rm test # clean up the FIFO we used earlier
```
The first two testcases are deterministic. The last isn't (it relies on a race condition); for testing purposes, I recommend adding a delay between the start of your program and the actual output to standard output, in order to ensure that the race condition is resolved in the way that exposes the error.
## Victory condition
This is a [code-golf](/questions/tagged/code-golf "show questions tagged 'code-golf'") challenge, so shorter is better. As (nearly) always, we're measuring the length of the program in bytes.

### How it works
After saving `Hello, world!` to the variable **h**, we do the following.
First, `(echo $h)2>&-` attempts to print `Hello, world!` to STDOUT. `2>&-` is required to prevent displaying the error message *echo: write error: Bad file descriptor* in case the write fails. Since writing to a named pipe that doesn't accept input would kill the Bash program with signal 13 (SIGPIPE), we execute the command in a subshell (`(...)`), so only the subshell will get killed.
Finally, if printing to STDOUT failed, the subshell will exit with a non-zero status code (141 for SIGPIPE, 1 for a generic error), so `echo Error writing \"$h\">&2` prints the desired message to STDERR.

# Challenge
Write a function or program that accepts a line of input, performs a very specific and oddly familiar shuffle on its characters, and outputs the result.
The required shuffling can be described using the following algorithm:
1. Label each character in the input with a 1 based index.
2. Write character number 1 as output.
3. Starting with character number 2, write every other character to the output in order, *excluding* character 2 itself. In other words, write characters 4, 6, 8, 10, and so on as output.
4. Starting with the next character number n not yet written as output, write every nth character to the output, *excluding* character n itself, and excluding any other character (by numeric label) you may have already written to the output.
5. Repeat step 4 as long it continues to add new characters to the output.
6. Write the remaining characters to output, in order.
# Example
1. Label the characters.
```
*1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27*
O L D D O C Y A K ' S B E A U T Y C O R N E R
```
2. Write the first character to output:
```
*~~**1**~~ 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27*
~~**O**~~ L D D O C Y A K ' S B E A U T Y C O R N E R
**O**
```
3. Write every other character starting with 2, excluding 2.
```
*~~1~~ 2 3 ~~**4**~~ 5 ~~**6**~~ 7 ~~**8**~~ 9 ~~**10**~~ 11 ~~**12**~~ 13 ~~**14**~~ 15 ~~**16**~~ 17 ~~**18**~~ 19 ~~**20**~~ 21 ~~**22**~~ 23 ~~**24**~~ 25 ~~**26**~~ 27*
~~O~~ L D D ~~**O**~~ C Y ~~**A**~~ K ~~**'**~~ S B ~~**E**~~ A ~~**U**~~ T ~~**Y**~~ ~~**C**~~ O ~~**R**~~ N ~~**E**~~ R
O **O A' EUYCRE**
```
4. The next character not yet written is character number 3; write every 3rd character starting with 3, but excluding character 3 itself, and any character already written.
```
*~~1~~ 2 3 ~~4~~ 5 ~~6~~ 7 ~~8~~ ~~**9**~~ ~~10~~ 11 ~~12~~ 13 ~~14~~ ~~**15**~~ ~~16~~ 17 ~~18~~ 19 ~~20~~ ~~**21**~~ ~~22~~ 23 ~~24~~ 25 ~~26~~ ~~**27**~~*
~~O~~ L D D ~~O~~ C ~~**Y**~~ ~~A~~ K ~~'~~ S ~~**B**~~ ~~E~~ A ~~U~~ T ~~Y~~ ~~C~~ O ~~R~~ N ~~E~~ ~~**R**~~
O O A' EUYCRE**YB R**
```
5. Repeat step 4 using the next character, character 5.
4. The next character not yet written is character number 5; write every 5th character starting with 5, but excluding character 5 itself, and any character already written. (This amounts to just character 25).
```
*~~1~~ 2 3 ~~4~~ 5 ~~6~~ 7 ~~8~~ ~~9~~ ~~10~~ 11 ~~12~~ 13 ~~14~~ ~~15~~ ~~16~~ 17 ~~18~~ 19 ~~20~~ ~~21~~ ~~22~~ 23 ~~24~~ ~~**25**~~ ~~26~~ ~~27~~*
~~O~~ L D D ~~O~~ C ~~Y~~ ~~A~~ K ~~'~~ S ~~B~~ ~~E~~ A ~~U~~ T ~~Y~~ ~~C~~ O ~~R~~ ~~**N**~~ ~~E~~ ~~R~~
O O A' EUYCREYB R**N**
```
5. The next character is 7; but 14, 21 have already been written, so no more characters would be output if we repeat step 4. Thus, we're done with 5.
6. Write the remaining characters out in order.
```
*~~1~~ **2 3** ~~4~~ **5** ~~6~~ **7** ~~8~~ ~~9~~ ~~10~~ **11** ~~12~~ **13** ~~14~~ ~~15~~ ~~16~~ **17** ~~18~~ **19** ~~20~~ ~~21~~ ~~22~~ **23** ~~24~~ ~~25~~ ~~26~~ ~~27~~*
~~O~~ **L D** **D** ~~O~~ **C** ~~Y~~ ~~A~~ **K** ~~'~~ **S** ~~B~~ ~~E~~ **A** ~~U~~ **T** ~~Y~~ ~~C~~ **O** ~~R~~ ~~N~~ ~~E~~ ~~R~~

# Rules
Input and output may be via standard input/standard output, strings, or arrays of characters.
If reading in as standard input you may at your convenience assume there's a trailing newline, or that the entire input contains the line. Newline characters do not participate in the shuffle.
Likewise, at your convenience, your output may either have a trailing newline or not.
Standard loopholes are disallowed.
This is a code golf competition. Smallest code in bytes wins.

#[[SortBy[Range@Length@#,FactorInteger[#][[1,1]]PrimeQ@#&]]]&
```
Unnamed function taking a list of characters as input and returning a list of characters.
`FactorInteger[#][[1,1]]` yields the smallest prime factor of `#` (and returns `1` if `#` equals `1`). Therefore `FactorInteger[#][[1,1]]PrimeQ@#` yields a strange expression: [`#`'s smallest prime factor] `False` if `#` is not prime, and `# True` if `#` is prime (these are unevaluated products of a number and a boolean).
`Range@Length@#` yields a list of the numbers up to the length of the input. Then `SortBy` sorts those numbers by the funny function described above. Mathematica is really type-sensitive in many ways, but cheerfully mixes them in other ways: expressions of the form [number] `False` are alphabetically sorted before expressions of the form [number] `True`, while ties are broken by sorting the numbers numerically. That produces exactly the permutation we want here, and `#[[...]]` permutes the characters of the input accordingly.

[Question]
[
A Diagonal [Sudoku](https://en.wikipedia.org/wiki/Sudoku) board is a special case of [Latin squares](https://en.wikipedia.org/wiki/Latin_square). It has the following properties:
* The board is a 9-by-9 matrix
* Each row contains the numbers `1-9`
* Each column contains the numbers `1-9`
* Each 3-by-3 sub-region contains the numbers `1-9`
* Both diagonals contains the numbers `1-9`
**Challenge:**
Create a program or function that outputs a complete board with all 81 numbers that complies with the rules above.
The number in at least one position must be random, meaning the result should vary accross executions of the code. The distribution is optional, but it must be possible to obtain at least 9 *structurally different* boards. A board obtained from another by *transliteration* is not considered *structurally* different. Transliteration refers to substituting each number *x* by some other number *y*, consistently in all positions of number *x*.
Hardcoding 9 boards is not accepted either.
**Rules:**
* Output format is optional, as long as it's easy to understand (list of list is OK)
* The random number can be taken as input instead of being created in the script, but only if your language doesn't have a RNG.
This is code golf so the shortest code in bytes win!
**Example boards:**
```
7 2 5 | 8 9 3 | 4 6 1
8 4 1 | 6 5 7 | 3 9 2
3 9 6 | 1 4 2 | 7 5 8

A full program that randomly gives a 9-by-9 matrix of digits.
By OP mentioning "it must be possible to obtain at least 9 structurally different boards", I believe it was to prevent using just trivial transformations like reflection and rotation. But [there are more possible transformations than that](http://www.sudocue.net/minx.php). I use two kinds of transformations:
* Permute R19C19, R28C28 and R37C37 (6 cases)
```
Example: Swap R19C19 and R28C28
a b c - - - A B C e d f - - - D F E
d e f - - - D E F b a c - - - A C B
g h j - - - G H J h g j - - - G J H
- - - - - - - - - - - - - - - - - -
- - - - - - - - - ==> - - - - - - - - -
- - - - - - - - - - - - - - - - - -
k l m - - - K L M l k m - - - K M L
n p q - - - N P Q s r t - - - R T S
r s t - - - R S T p n q - - - N Q P
```
* Reverse the order of boxes in both dimensions (2 cases: reverse both or keep intact)
```
a b c - - - A B C K L M - - - k l m
d e f - - - D E F N P Q - - - n p q
g h j - - - G H J R S T - - - r s t
- - - - - - - - - - - - - - - - - -
- - - - - - - - - ==> - - - - - - - - -
- - - - - - - - - - - - - - - - - -
k l m - - - K L M A B C - - - a b c
n p q - - - N P Q D E F - - - d e f
r s t - - - R S T G H J - - - g h j
```
resulting in 12 structurally different boards. Note that, in both cases, the thing that changes on the diagonals is the *order* of the digits. Also, the center box is always intact, so no two boards are equivalent under transliteration.

[
Some trading cards have real value and can be sold for money. Bending the cards is frowned upon because it takes away their value and makes them look less new. Say you have a deck of trading cards (Pokemon, Magic, etc.) and you want to shuffle them. Instead of doing the bridge that bends all of the cards, another simple way to shuffle cards is to put them into piles. Here's what I mean.
# Background
With a 60 card deck in need of shuffling, you could separate the 60 cards into three piles of 20 cards. There are multiple ways to do this, the most plain being to put a card into pile A, then one into pile B, then one into pile C. Another way is to put a card into pile C, then B, then A. There are also ways to spread the cards across the piles unevenly. Here's one: put a card in pile A, put another card in A, then put a card in pile B, then put a card in pile C.
# Challenge
Create a full program that will output `even` if a certain way to shuffle into piles spreads the cards in the piles evenly, and outputs `uneven` and the number of cards in each pile otherwise.
# Input
Input will be taken through STDIN or the closest alternative (no functions).
```
[sequence] [deck size]
```
* `sequence` is a string of characters. It tells the pattern the cards are laid down into the piles. Each different character corresponds to a single pile. This string will always be under the deck size and will contain only capital letters A-Z.
* `deck size` is an integer that specifies how many cards are in the deck. If deck size is 60, the number of cards in the deck is 60.
# Output
```
even
```
If the number of cards in each pile at the end of the shuffle are the same, your program should output this.
```
uneven [pile1] [pile2] [...]
```
If the number cards in each pile at the end of the shuffles are the not the same, your program should output `uneven` and the number of cards in each pile like this: `uneven 20 30` if pile A contains 20 canrds and pile B contains 30. The order of the pile numbers does not matter.
# Other information
* This is a code golf challenge, so the shortest code in bytes on September 25 wins. If there is a tie in byte counts, the code that was submitted first wins.
* Your program must be a program, not a function.
* If possible, please include a link to an online interpreter or a link to a place where I can download an interpreter for your language in your answer.
* Anything I do not specify within this challenge is fair game, meaning if I don't say it, it's up to you. If anything is vague, tell me and I will edit the answer accordingly. (Hopefully this goes more smoothly than my last challenge.)
# Examples
```
Input | Output | Alternate outputs (if uneven)
|
ABC 30 | even
ABC 31 | uneven 11 10 10 | uneven 10 11 10 | uneven 10 10 11
BCA 60 | even
BBA 24 | uneven 8 16 | uneven 16 8
ABACBC 120 | even

# Python 3.x, 106 ~~128~~ ~~138~~ bytes
```
s,n=input().split()
n=int(n)
t=(s*n)[:n]
*z,=map(t.count,set(t))
b=z[:-1]!=z[1:];print("un"*b+"even",*z*b)
```
This duplicates the input sequence (more times than needed, which is good enough) and then takes only the first `n` characters. These are counted and either `uneven` or `even` is chosen, and if the former, the counts also are printed with `print(*z)`, which automatically unpacks `z` for me.
Saved 32 bytes thanks to xnor and Sp3000!
Also, **Python 3.5** has a new feature that allows this 102 byte solution:
```
s,n=input().split()
n=int(n)
t=(s*n)[:n]
*z,=map(t.count,{*t})
b=len({*z})>1;print("un"*b+"even",*z*b)
```
`len({*z})>1` unpacks the list `z`, makes a set from it, then checks to see if it has more than one element. It is `{*z}` specifically that's new.

e# The result with be an empty array (falsy) iff all elements are equal.

@+ e# Concatenate ["uneven"] with the array of multiplicities.
S* e# Join, separating by spaces.

A subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements. A strictly increasing subsequence is a subsequence in which every element is bigger than the preceding one.
The heaviest increasing subsequence of a sequence is the strictly increasing subsequence that has the biggest element sum.
Implement a program or function in your language of choice that finds the element sum of the heaviest increasing subsequence of a given list of non-negative integers.
Examples:
```
[] -> 0 ([])
[3] -> 3 ([3])
[3, 2, 1] -> 3 ([3])
[3, 2, 5, 6] -> 14 ([3, 5, 6])
[9, 3, 2, 1, 4] -> 9 ([9])
[3, 4, 1, 4, 1] -> 7 ([3, 4])
[9, 1, 2, 3, 4] -> 10 ([1, 2, 3, 4])
[1, 2, 4, 3, 4] -> 10 ([1, 2, 3, 4])
[9, 1, 2, 3, 4, 5, 10] -> 25 ([1, 2, 3, 4, 5, 10])
[3, 2, 1, 2, 3] -> 6 ([1, 2, 3])
```
Note that you only have to give the element sum of the heaviest increasing subsequence, not the subsequence itself.

Runtime analysis:
Each element has its insertion position looked up once, is inserted once, and is possibly deleted once, in addition to a constant number of value lookups per loop. Since I am using the built-in bisect package and the [blist package](https://pypi.python.org/pypi/blist/), each of those operations are `O(log n)`. Thus, the overall runtime is `O(n log n)`.
The program works by maintaining a sorted list of best possible increasing subsequences, represented as a tuple of ending value and sequence sum. An increasing subsequence is in that list if there are no other subsequences found so far whose ending value is smaller and sum is at least as large. These are maintained in increasing order of ending value, and necessarily also in increasing order of sum. This property is maintained by checking the successor of each newly found subsequence, and deleting it if its sum is not large enough, and repeating until a subsequence with a larger sum is reached, or the end of the list is reached.

this uses fenwick trees (a maximum fenwick tree) to find maxima of certain subsequences.
basically, in the underlying array of the datatype, each place is matched with an element from the input list, in the same order. the fenwick tree is initialized with 0 everywhere.
from the smallest to the biggest, we take an element from the input list, and look for the maximum of the elements to the left. they are the elements that may be before this one in the subsequence, because they are to the left in the input sequence, and are smaller, because they entered the tree earlier.
so the maximum we found is the heaviest sequence that can get to this element, and so we add to this the weight of this element, and set it in the tree.
then, we simply return the maximum of the whole tree is the result.

# Python, O(n log n)
I used an index transform and a nifty data structure (binary indexed tree) to trivialize the problem.
```
def setmax(a, i, v):
while i < len(a):
a[i] = max(a[i], v)
i |= i + 1
def getmax(a, i):
r = 0
while i > 0:
r = max(r, a[i-1])
i &= i - 1
return r
def his(l):
maxbit = [0] * len(l)
rank = [0] * len(l)
for i, j in enumerate(sorted(range(len(l)), key=lambda i: l[i])):
rank[j] = i
for i, x in enumerate(l):
r = rank[i]
s = getmax(maxbit, r)
setmax(maxbit, r, x + s)
return getmax(maxbit, len(l))
```
The binary indexed tree can do two operations in log(n): increase a value at index i and get the maximum value in [0, i). We initialize every value in the tree to 0. We index the tree using the rank of elements, not their index. This means that if we index the tree at index i, all elements [0, i) are the elements smaller than the one with rank i. This means that we get the maximum from [0, i), add the current value to it, and update it at i. The only issue is that this will include values which are less than the current value, but come later in the sequence. But since we move through the sequence from left-to-right and we initialized all values in the tree to 0, those will have a value of 0 and thus not affect the maximum.

An *acyclical grid* is a mapping of an acyclical graph (that is, a tree) where each node has no more than four edges onto a toroidal rectangular grid such that each cell of the grid is occupied by a node. Here is an example of an acyclical grid:
```
┴─┐╵╵│└┘└╴╶┴┬
╴╷╵┌┐│╷┌┬┐╶┐├
╷│╷╵│├┘│╵└╴│╵
┘└┴┐│└┬┤┌─┬┴─
╷╶─┤│╷╵├┤╶┘╶┐
│╶┐└┤└┬┤╵╷╶─┤
┤╷└─┴┬┤└┐└┬┬┴
│├──┐│├╴├─┤├╴
┘└┐┌┴┤└┐├╴╵╵┌
┌┬┘╵┌┴┐╵└─┐╶┘
┤└─┐│╷│┌┬╴╵╷╶
```
Some browser fonts have trouble rendering this in a properly monospaced way. If the grid looks off, please copy-paste it into a text editor of your choice.
Notice that this grid is toroidal: the left and right, as well as the top and bottom are connected preserving the axis you are moving along. For example, if you move left in the third row you eventually end up on the right of the third row and vice versa.
This grid is composed of box-drawing characters which fall into four classes:
1. The characters `╵` , `╶`, `╷`, and `╴` denote leaves (nodes with one edge)
2. The characters `│` and `─` denote nodes with two edges in a collinear arrangement
3. The characters `┴`, `├`, `┬`, and `┤` denote nodes with three edges
4. The characters `└`, `┌`, `┐`, and `┘` denote nodes with two edges in a perpendicular arrangement
The *characteristic matrix* of an acyclical grid is a matrix comprising for each cell in the acyclical grid the class of the node positioned there. For instance, the characteristic matrix of the aforementioned grid is this:
```
3241124441133
1114424232123
1211234214121
4434243342332
1123211331414
2144343311123
3142333444333
2322423131331
4444334431114
4341434142414
3424212431111
```
A *net puzzle* is an *n* × *m* matrix of integers in the range from 1 to 4 such that it is the characteristic matrix of exactly one acyclical grid.
If you want to gain an intuitive understanding about net puzzles, you can play [net](http://www.chiark.greenend.org.uk/~sgtatham/puzzles/js/net.html) from Simon Tatham's puzzle collection. Make sure that “wrapping” and “ensure unique solution” are both checked and that “barrier probability” is set to 0.
## The challenge
Write a function or program that given two integers *n* and *m* in the range from 3 to 1023 generates a net puzzle of dimension *n* × *m.* You may optionally receive a third integer *p* in the range from 1 to 1023.
If you implement the variant with two arguments (the non-deterministic variant), then your submission shall with great probability return a different puzzle each time it is called. If you implement the variant with three arguments (the deterministic variant), then the set of puzzles generated for all *p* for a given pair (*n, m*) shall contain at least four different puzzles for each pair (*n, m*).
There are no further restrictions with respect to input and output.
## Scoring
This challenge is code golf. The solution with the least number of octets wins.

I can't believe that it went unanswered for, like, six and a half years?
Implements the three-argument version. It is a function that takes `n m p` as three separate parameters and builds a valid net puzzle deterministically.
Basically what it does is to build one asymmetric and easily constructible net puzzle of size `n m`, and then permute its rows based on `p`.
### What it builds & Why it is valid for this challenge
The result for `f[5;6;0]` is this:
```
1 1 1 1 1 1
2 2 2 2 2 2
2 2 2 2 2 2
2 2 2 2 2 2
3 3 3 3 4 4
```
In box drawing chars:
```
1 1 1 1 1 1 : ╷╷╷╷╷╷
2 2 2 2 2 2 : ││││││
2 2 2 2 2 2 : ││││││
2 2 2 2 2 2 : ││││││
3 3 3 3 4 4 : ┴┴┴┴┘└
```
And it has a unique solution, as well as its reflections and rotations (as in APL sense; cyclically moving rows and columns).
Why unique solution? First, the solution is an unrooted tree (in graph-theoretical sense); if a configuration has a cycle, then it is not a solution because it necessarily has two or more disjoint parts. Then, the 2's must be all aligned either horizontally or vertically, but if they're horizontal then they form one or more cycles of their own. So they must be vertical. Then the orientation of 1's are fixed (downwards), and then the 3's (disconnected to the lower side). Finally the orientations for 4's are fixed in order to connect everything.
The code is easy:
```
&(0;y;y*x-2;y-2;2) Create an array of:
m copies of 1's, m*(n-2) copies of 2's,
(m-2) copies of 3's, and 2 copies of 4's
(x,y)# Reshape into n-row, m-col matrix
```
For "at least four distinct puzzles" part, I had to use two different permuting methods because of the 3x3 grid (single reflection gives at most 2; stepwise rotation gives at most either `n` or `m`). I went for pure row permutation because applying two separate transforms was too long.
For code, `!x` creates the identity permutation vector `0 1 2 ... (n-1)`, `x!z+` rotates it by `p` steps, and `z|:/` reverses it `p` times. This creates `lcm(2, n)` unique grids, which is always at least 4.
I know, it's likely against the original intent of the challenge, but [this is not the first time I exploited "generate at least x distinct grids"](https://codegolf.stackexchange.com/a/197156/78410) :P

In Conway's Game of Life, a cell is in a state of either on or off, depending on the on-and-off state of the eight cells surrounding it.
We can simulate this using a logic gate network with some sort of clock signal that updates every cell all at once. Your task in this problem is to build the logic gate network for a single cell that will update the new state of the cell given the state of its neighbours.
This cell is a logic gate network that takes eight neighbour-cell inputs `N1, N2, ..., N8`, the current on/off state of its own cell `L`, and 18 "rule" inputs `B0, B1, B2, ..., B8` and `S0, S1, S2, ..., S8`, and evaluates a new `L` value (to an output `L'`) as follows:
* if `L` is currently `0` and `Bn` is on where `n` is the number of `N1, N2, ..., N8` that are currently set at `1`, then `L'` is set to `1`. Otherwise, it stays `0`.
* if `L` is currently `1` and `Sn` is off where `n` is the number of `N1, N2, ..., N8` that are currently set at `1`, then `L'` is set to `0`. Otherwise, it stays `1`.
In the example of Conway's Game of Life, `B3`, `S3`, and `S2` are on, while the rest of them are all off.
Unlike my previous logic gate tasks, for this task you may use any two-input logic gates you want, not just NAND gates. This includes exotic gates such as `if A then B`, `A or not B`, or simply `A`, a gate that takes two inputs and always returns the first one (although I'm not sure why you'd want to use that one, you are allowed to). You are allowed unlimited constants, splits, and ground wires.
The network to use the fewest logic gates to achieve this wins.

## 89 gates using sorting network
I think the basic structure pretty much has to be a sum unit and a demultiplexer which uses the output of the sum unit and `L` to select the appropriate `B_i` or `S_i`. So there's one decision which is definitely interesting, and one dependent decision which may be interesting.
The definitely interesting decision is the output format of the sum. The dependent decision is whether to structure the 18-value demux as two 9-value demuxes (switched by the sum) feeding into a 2-value demux (switched by `L`) or as 9 2-value demuxes feeding into a 9-value demux.
I'm choosing to have the sum output in unary, so the 9-value demux is just 8 2-input demuxes in a chain, and the dependent decision is uninteresting.
### Counting in unary via sorting network
`AND` and `OR` gates can be considered instead to be `MIN` and `MAX` gates, giving a two-gate way of sorting two bits:
These pairwise sorting operators can be combined to sort any number of bits (and, if generalised to `MIN` and `MAX` operations over any total order, to sort any number of elements of that order) in a [sorting network](http://en.wikipedia.org/wiki/Sorting_network). The standard notation shows just which lines are sorted at each step, and drawing the gates would be quite messy. The best possible sorting network for 8 inputs requires 19 pairwise sorters, which can be arranged as so:
So for a total of 38 gates, the inputs `N1` to `N8` are transformed into 8 intermediate values `T1 = MAX(N1, ..., N8)` to `T8 = MIN(N1, ..., N8)`. Effectively `Ti` is true iff at least `i` of the inputs are true.
### Demultiplexing
A 2-value demultiplexer can be done with 3 gates in many many ways. E.g.
An `n`-value demux taking unary input `S_i` and selecting between values `V_i` can be built up recursively from `n-1` 2-value demuxes as follows:
```
d_0 = V_0
d_{i+1} = S_{i+1} ? V_{i+1} : d_i
```
So two 9-value demuxes and a 2-value demux takes 17 demuxes; so does 9 2-value demuxes and a single 9-value demux.
So the grand total gate count is 38 for the sorting network + 17\*3 for the demuxes, giving 89.

Such readable. Much built-in. Wow.
We use the fact that the lexicographic index of a permutation is the sum over the elements of the permutations of the number of inversions above that element (values after it but below it) multiplied by the factorial of the number of elements after it. Rather than evaluate this polynomial-like expression term by term, we use something akin to [Horner's method](http://en.wikipedia.org/wiki/Horner's_method).
Rather then looping over array indices, we repeatedly remove the first element of the list and process the remaining elements. The expression `sorted(p).index(p.pop(0))` counts the number of inversions past the first index by taking its position in the sorted list, while at the same time doing the removal.
Sadly, I had to use Python 2 and take 4 more characters for `raw_input` (though -1 for `print`) because in Python 3 the `map(int,...)` produces a map object, which doesn't support list operations,

Then create a lookup table using the original and sorted lists:
```
abcdefghijklmnopqrstuvwxyz
||||||||||||||||||||||||||
eisultnarocmdpvqbgfhjkwxyz
```
Python dictionary:
```
{'o': 'v', 'n': 'p', 'm': 'd', 'l': 'm', 'k': 'c', 'j': 'o', 'i': 'r', 'h': 'a', 'g': 'n', 'f': 't', 'e': 'l', 'd': 'u', 'c': 's', 'b': 'i', 'a': 'e', 'z': 'z', 'y': 'y', 'x': 'x', 'w': 'w', 'v': 'k', 'u': 'j', 't': 'h', 's': 'f', 'r': 'g', 'q': 'b', 'p': 'q'}
```
And now encode the original text with this lookup table:

**Rules:**
* Your program will accept a string and output one.
* Convert all input to lowercase before doing anything
* I don't care how you do the list sorting, but only count lowercase letters
* Bonus points (-30) for making a decryptor (no copying the decryption list, do it from scratch
* This is [code-golf](/questions/tagged/code-golf "show questions tagged 'code-golf'"), so the shortest code wins!
* Have fun!

# Smalltalk, 138

m:=(s select:[:c|cisLetter])asLowercase asBag sortedCounts map:#value.
i:=($ato:$z).m:=m,(i copyWithoutAll:m).
s copyTransliterating:i to:m
```
the decoder is:
```
s copyTransliterating:m to:i

but as (if I understand correctly) I may not reuse "i" and "m", I'll golf without it. Code above has two additional CRs inserted for readability, which were uncounted in the char count.

Not the shortest code at all but as Python is not yet represented and as I see "I love python!" in the problem setting, here I go,

```
Expects the input string to be passed via the command line. (number of characters are reduced to **122** if the input string was magically inserted into the variable "s")
```
a=map(chr,range(97,123));print"".join([sorted(a,key=lambda x:-s.lower().count(x))[ord(c)-97]if c in a else c for c in s])

## GolfScript 17
```
10\?@abs*\abs/10%
```
GolfScript can't handle real numbers well, but multiplying by powers of 10 is equivalent.
Here's an explanation and walkthrough with sample input, for any of you who are new to GolfScript, since I think this is a nice simple introduction:
```
59 -17 5
10\ #Place 10 on the stack and then switch the top 2 elements
-> 59 -17 10 5
? #Exponentiate
-> 59 -17 100000
@ #Rotate top 3 elements
-> -17 100000 59
abs #Take absolute value of top element
-> -17 100000 59
* #Multiply the top 2 elements
-> -17 5900000
\ #Switch top 2 elements
-> 5900000 -17
abs #Take absolute value of top element
-> 5900000 17
/ #Do integer division
-> 347058
10% #Place 10 on the stack and then take modulo
-> 8
```
[Answer]
## Java
```
static int digit(int N, int D, int R) {
if (D < 0) D = -D;
if (N < 0) N = -N;
int Q=0;
while (R-- > 0) {
while (N >=D) N -=D;
int P=N = ((N+N)<<1)+N;
for (Q=P^P; N >D; N -=D) Q++;
while (P >=D) P -=D;
N = P<<1;
}
for (; N >= 0; N -=D) R++;
return (Q<<1) + R;
}
```
This code
* avoids multiplication and division
* splits decimal digit in 5- and 2-digit (Q and final R) internally
---
*Explanation*
When dividing manually you get digits by multiplying remainders by 10 and comparing the results to multiples of the divisor
```
10 / 17 = Digit 0, Remainder 10 (x 10)
100 / 17 = Digit 5, Remainder 15 (x 10)
150 / 17 = Digit 8, Remainder 14 (x 10)
140 / 17 = Digit 8, Remainder 4 (x 10)
etc.
```
So the basic code (ignoring all digits except the R-th) would be
```
static int digitA(int N, int D, int R) {
while (R-- > 0) {
N = N % D;
N = N * 10;
}
return N / D;
}
```
Replacing multiplications and divisions by adding/subtracting and shifting results in
```
while (R-- > 0) {
while (N >= D) N = N - D;
N = ((N << 2) + N) << 1;
}
int digit = 0;
while (N > D) { digit++; N = N - D; }
return digit;
```
As `R` is `-1` after the first loop, it can be used to replace `digit` afterwards.
With avoiding shifting by more than 1 and introducing intermediate `P` the code becomes
```
while (R-- > 0) {
while (N >= D) N = N - D;
int P = ((N + N) << 1) + N;
N = P << 1;
}
for ( ; N >= D; N = N - D) R++;
return R;
```
The number of loop runs can be reduced by "splitting the decimal digit into two digits with base 5 and 2".
The above manual division schema would become something like
```
10 / 17 = 2-Digit 0, Remainder 10 (x 5)
50 / 17 = 5-Digit 2, Remainder 16 (x 2)
32 / 17 = 2-Digit 1, Remainder 15 (x 5) --> 10-digit = 2*2 + 1
75 / 17 = 5-Digit 4, Remainder 7 (x 2)
14 / 17 = 2-Digit 0, Remainder 14 (x 5) --> 10-digit = 4*2 + 0
70 / 17 = 5-Digit 4, Remainder 2 (x 2)
4 / 17 = 2-Digit 0, Remainder 4 (x 5) --> 10-digit = 4*2 + 0
etc.
```
As only the R-th decimal digit is to be returned, only the R-th 5-digit before the R-th 2-digit is required to compose the R-th decimal digit.
```
int P=N = ((N+N)<<1)+N; // N = N * 5
for (Q=P^P; N >D; N -=D) Q++; // Q=digit(5)
//...
return (Q<<1) + R;
```
The rest is some "obfuscation"
* `P^P` is zero - inspired by machine code where XORing may be the most efficient way to set a register to zero :-)
* The line `while (P >=D) P -=D;` is the same as `P=N;` - but is more "smiling" :-)

The following code counts the number of digits after the decimal point, e.g. for `N = 3` and `D = 17`, `fracnum(N,D,7) = 5` since N/D = 0.176470588235.
```
def fracnum(N,D,R):
v, d = abs(N)*10, abs(D)
while R:
(v, r, R) = (v*10, v, R-1) if v < d else ((v%d)*10, v//d, R-1)
return r
```
This function can be written more compact as:
```
def f(N,D,R):
v,d=abs(N)*10,abs(D)
while R:v,r=(((v%d)*10,v//d),(v*10,v))[v<d];R-=1
return r
```

## Awk: 38

Called by the slightly cumbersome `awk -f division.awk -v n=? -v d=? -v r=?` where `?` represents the variable you want in there. Note that this is limited by precision, so choice of `1 4 3` would result in a blank line.

This now handles rational numbers close to zero.
Should work to (one million places - no. places to the left of decimal point).
```
f[n_,d_,r_]:=({w,z}=RealDigits[N[n/d,10^6]];If[z+r<1,0,w[[z+r]]])
```
**Testing**
The following returns the digits at positions `min` through `max`, allowing for easy checking of results.
```
g[n_, d_, {min_, max_}] := Grid@{{"num", "den", "decimal", "digits " <> ToString@min <>
" to " <> ToString@max}, {n, d, N[n/d, max], Table[f[n, d, k], {k, min, max}]}}
```
Verify the digits of 1/7 from 3 to 7 places to the right of the decimal point.
```
g[1, 7, {3, 7}]
```
