Leetcode 3208. Alternating Groups II

Given a circular binary array and integer k, count how many contiguous length-k segments are alternating (every adjacent pair within the segment differs). Because of the circular wrap, this reduces to checking windows where all k-1 internal adjacent pairs are different (a sliding-window over adjacency flags).
