Suppose we have a class called Math then nobody will want to create object of class Math and then invoke methods like ceil and floor and fabs on it.( >> Math.floor(3.14))
So we make them static.
One would use @classmethod when he/she would want to change the behaviour of the method based on which subclass is calling the method. remember we have a reference to the calling class in a class method.
While using static you would want the behaviour to remain unchanged across subclasses

Mary has on a sheet of paper a list of distances between these towns. ls = [50, 55, 57, 58, 60]. John is tired of driving and he says to Mary that he doesn't want to drive more than t = 174 miles and he will visit only 3 towns.
#
# Which distances, hence which towns, they will choose so that the sum of the distances is the biggest possible to please Mary and John?
#
# Example:
# With list ls and 3 towns to visit they can make a choice between: [50,55,57],[50,55,58],[50,55,60],[50,57,58],[50,57,60],[50,58,60],[55,57,58],[55,57,60],[55,58,60],[57,58,60].
#
# The sums of distances are then: 162, 163, 165, 165, 167, 168, 170, 172, 173, 175.
#
# The biggest possible sum taking a limit of 174 into account is then 173 and the distances of the 3 corresponding towns is [55, 58, 60].
#
# The function chooseBestSum (or choose_best_sum or ... depending on the language) will take as parameters t (maximum sum of distances, integer >= 0), k (number of towns to visit, k >= 1) and ls (list of distances, all distances are positive or null integers and this list has at least one element). The function returns the "best" sum ie the biggest possible sum of k distances less than or equal to the given limit t, if that sum exists, or otherwise nil, null, None, Nothing, depending on the language.
#
# With C++, C, Rust, Swift, Go, Kotlin, Dart return -1.
#
# Examples:
# ts = [50, 55, 56, 57, 58] choose_best_sum(163, 3, ts) -> 163
#
# xs = [50] choose_best_sum(163, 3, xs) -> nil (or null or ... or -1 (C++, C, Rust, Swift, Go)

'''
A 'polite' iterator object which provides many useful methods.
While generators often provide a cleaner approach to problems, their
indeterminate and temporal nature make some problems -- such as those
that require looking ahead or knowing the length of a sequence -- more
difficult. Politer is an attempt to provide methods for solving those
problems, in two ways:
1) It allows you to send values back to the generator, which will put
them on top of the 'stack'. As a convenience, it provides a prev()
method for the common use case of rewinding the generator exactly one
value.
2) It provides a 'lazy' implementation of the sequence protocol,
allowing you to get the politer's length, index into it, etc. just like
a list. The politer will internally unroll as much of the generator as
necessary in order to perform the requested operation. It also provides
some 'lazy' methods to avoid using the more exhaustive ones, such as
at_least() and popped().
Note that pulling values off the politer using next() will change its
length and the indices of the contained elements -- the politer is a
'list of uniterated values,' albeit with the ability to send values
back.
Politers use deques internally to hold their unrolled values. They
should perform well for relatively short-range looks ahead during
iteration, but if you intend to perform many sequence operations that
target the 'far end' of the generator, you will probably do better just
casting the generator to a list.
