Arithmetic progression def arithmetic_progression(elems): An arithmetic progression is a numerical sequence so that the stride between each two consecutive elements is constant throughout the sequence. For example, [4, 8, 12, 16, 20] is an arithmetic progression of length 5, starting from the value 4 with a stride of 4. Given a list of elems guaranteed to consist of positive integers listed in strictly ascending order, find and return the longest arithmetic progression whose all values exist somewhere in that sequence....
