Provide tags and a correct Python 3 solution for this coding contest problem. You are given a uppercase Latin letters 'A' and b letters 'B'. The period of the string is the smallest such positive integer k that s_i = s_{i~mod~k} (0-indexed) for each i. Note that this implies that k won't always divide a+b = |s|. For...
