Description

Alice and Bob play a game. Alice starts with word = "a". You are given positive integer k and integer array operations. Bob asks Alice to apply each operation:

- operations[i] == 0: append a copy of word to itself.

- operations[i] == 1: increment each character cyclically, then append the result.

Return the k-th character of word after all operations ('z' wraps to 'a').
