/**
* Problem
Do you ever become frustrated with television because you keep seeing the same things, recycled over and over again? Well I personally don't care about television, but I do sometimes feel that way about numbers.
Let's say a pair of distinct positive integers (n, m) is recycled if you can obtain m by moving some digits from the back of n to the front without changing their order. For example, (12345, 34512) is a recycled pair since you can obtain 34512 by moving 345 from the end of 12345 to the front. Note that n and m must have the same number of digits in order to be a recycled pair. Neither n nor m can have leading zeros.
Given integers A and B with the same number of digits and no leading zeros, how many distinct recycled pairs (n, m) are there with A ² n < m ² B?
Input
The first line of the input gives the number of test cases, T. T test cases follow. Each test case consists of a single line containing the integers A and B.
Output
For each test case, output one line containing "Case #x: y", where x is the case number (starting from 1), and y is the number of recycled pairs (n, m) with A ² n < m ² B.
Limits
1 ² T ² 50.
A and B have the same number of digits.
Small dataset
1 ² A ² B ² 1000.
Large dataset
1 ² A ² B ² 2000000.
Sample
Input
Output
4
1 9
10 40
100 500
1111 2222
Case #1: 0
Case #2: 3
Case #3: 156
Case #4: 287
Are we sure about the output to Case #4?
Yes, we're sure about the output to Case #4.

/**
* Problem
*
* You're watching a show where Googlers (employees of Google) dance, and then
* each dancer is given a triplet of scores by three judges. Each triplet of
* scores consists of three integer scores from 0 to 10 inclusive. The judges
* have very similar standards, so it's surprising if a triplet of scores
* contains two scores that are 2 apart. No triplet of scores contains scores
* that are more than 2 apart.
*
* For example: (8, 8, 8) and (7, 8, 7) are not surprising. (6, 7, 8) and (6, 8,
* 8) are surprising. (7, 6, 9) will never happen.
*
* The total points for a Googler is the sum of the three scores in that
* Googler's triplet of scores. The best result for a Googler is the maximum of
* the three scores in that Googler's triplet of scores. Given the total points
* for each Googler, as well as the number of surprising triplets of scores,
* what is the maximum number of Googlers that could have had a best result of
* at least p?
*
* For example, suppose there were 6 Googlers, and they had the following total
* points: 29, 20, 8, 18, 18, 21. You remember that there were 2 surprising
* triplets of scores, and you want to know how many Googlers could have gotten
* a best result of 8 or better.
*
* With those total points, and knowing that two of the triplets were
* surprising, the triplets of scores could have been:
*
* 10 9 10 6 6 8 (*) 2 3 3 6 6 6 6 6 6 6 7 8 (*)
*
* The cases marked with a (*) are the surprising cases. This gives us 3
* Googlers who got at least one score of 8 or better. There's no series of
* triplets of scores that would give us a higher number than 3, so the answer
* is 3.
*
* Input
*
* The first line of the input gives the number of test cases, T. T test cases
* follow. Each test case consists of a single line containing integers
* separated by single spaces. The first integer will be N, the number of
* Googlers, and the second integer will be S, the number of surprising triplets
* of scores. The third integer will be p, as described above. Next will be N
* integers ti: the total points of the Googlers.
*
* Output
*
* For each test case, output one line containing "Case #x: y", where x is the
* case number (starting from 1) and y is the maximum number of Googlers who
* could have had a best result of greater than or equal to p.
*
* Limits
*
* 1 ⤠T ⤠100. 0 ⤠S ⤠N. 0 ⤠p ⤠10. 0 ⤠ti ⤠30. At least S of the ti values
* will be between 2 and 28, inclusive.
*
* Small dataset
*
* 1 ⤠N ⤠3.
*
* Large dataset
*
* 1 ⤠N ⤠100.
*
* Sample
*
* Input Output 4 Case #1: 3 3 1 5 15 13 11 Case #2: 2 3 0 8 23 22 21 Case #3: 1
* 2 1 1 8 0 Case #4: 3 6 2 8 29 20 8 18 18 21

/**
* Problem
*
* You're watching a show where Googlers (employees of Google) dance, and then
* each dancer is given a triplet of scores by three judges. Each triplet of
* scores consists of three integer scores from 0 to 10 inclusive. The judges
* have very similar standards, so it's surprising if a triplet of scores
* contains two scores that are 2 apart. No triplet of scores contains scores
* that are more than 2 apart.
*
* For example: (8, 8, 8) and (7, 8, 7) are not surprising. (6, 7, 8) and (6, 8,
* 8) are surprising. (7, 6, 9) will never happen.
*
* The total points for a Googler is the sum of the three scores in that
* Googler's triplet of scores. The best result for a Googler is the maximum of
* the three scores in that Googler's triplet of scores. Given the total points
* for each Googler, as well as the number of surprising triplets of scores,
* what is the maximum number of Googlers that could have had a best result of
* at least p?
*
* For example, suppose there were 6 Googlers, and they had the following total
* points: 29, 20, 8, 18, 18, 21. You remember that there were 2 surprising
* triplets of scores, and you want to know how many Googlers could have gotten
* a best result of 8 or better.
*
* With those total points, and knowing that two of the triplets were
* surprising, the triplets of scores could have been:
*
* 10 9 10 6 6 8 (*) 2 3 3 6 6 6 6 6 6 6 7 8 (*)
*
* The cases marked with a (*) are the surprising cases. This gives us 3
* Googlers who got at least one score of 8 or better. There's no series of
* triplets of scores that would give us a higher number than 3, so the answer
* is 3.
*
* Input
*
* The first line of the input gives the number of test cases, T. T test cases
* follow. Each test case consists of a single line containing integers
* separated by single spaces. The first integer will be N, the number of
* Googlers, and the second integer will be S, the number of surprising triplets
* of scores. The third integer will be p, as described above. Next will be N
* integers ti: the total points of the Googlers.
*
* Output
*
* For each test case, output one line containing "Case #x: y", where x is the
* case number (starting from 1) and y is the maximum number of Googlers who
* could have had a best result of greater than or equal to p.
*
* Limits
*
* 1 ⤠T ⤠100. 0 ⤠S ⤠N. 0 ⤠p ⤠10. 0 ⤠ti ⤠30. At least S of the ti values
* will be between 2 and 28, inclusive.

* Problem C. Recycled Numbers
*
* Do you ever become frustrated with television because you keep seeing the
* same things, recycled over and over again? Well I personally don't care about
* television, but I do sometimes feel that way about numbers.
*
* Let's say a pair of distinct positive integers (n, m) is recycled if you can
* obtain m by moving some digits from the back of n to the front without
* changing their order. For example, (12345, 34512) is a recycled pair since
* you can obtain 34512 by moving 345 from the end of 12345 to the front. Note
* that n and m must have the same number of digits in order to be a recycled
* pair. Neither n nor m can have leading zeros.
*
* Given integers A and B with the same number of digits and no leading zeros,
* how many distinct recycled pairs (n, m) are there with A ⤠n < m ⤠B?
*
* Input
*
* The first line of the input gives the number of test cases, T. T test cases
* follow. Each test case consists of a single line containing the integers A
* and B.
*
* Output
*
* For each test case, output one line containing "Case #x: y", where x is the
* case number (starting from 1), and y is the number of recycled pairs (n, m)
* with A ⤠n < m ⤠B.
*
* Limits
*
* 1 ⤠T ⤠50.
*
* A and B have the same number of digits.
Small dataset

* Problem C. Recycled Numbers
*
* Do you ever become frustrated with television because you keep seeing the
* same things, recycled over and over again? Well I personally don't care about
* television, but I do sometimes feel that way about numbers.
*
* Let's say a pair of distinct positive integers (n, m) is recycled if you can
* obtain m by moving some digits from the back of n to the front without
* changing their order. For example, (12345, 34512) is a recycled pair since
* you can obtain 34512 by moving 345 from the end of 12345 to the front. Note
* that n and m must have the same number of digits in order to be a recycled
* pair. Neither n nor m can have leading zeros.
*
* Given integers A and B with the same number of digits and no leading zeros,
* how many distinct recycled pairs (n, m) are there with A ⤠n < m ⤠B?
*
* Input
*
* The first line of the input gives the number of test cases, T. T test cases
* follow. Each test case consists of a single line containing the integers A
* and B.
*
* Output
*
* For each test case, output one line containing "Case #x: y", where x is the
* case number (starting from 1), and y is the number of recycled pairs (n, m)
* with A ⤠n < m ⤠B.
*
* Limits
*
* 1 ⤠T ⤠50.
*
* A and B have the same number of digits.
Small dataset
1 ⤠A ⤠B ⤠1000.
Large dataset
1 ⤠A ⤠B ⤠2000000.
