Provide tags and a correct Python 3 solution for this coding contest problem. A bitstring is a string consisting only of the characters 0 and 1. A bitstring is called k-balanced if every substring of size k of this bitstring has an equal amount of 0 and 1 characters (k/2 of each). You are given an integer k and a str...
