LeetCode ProblemMinimum Time to Revert Word to Initial State II
You are given a 0-indexed string word and an integer k. At every second, you must perform the following operations: Note that you do not necessarily need to add the same characters that you removed. However, you must perform both operations at every second. Return the minimum time greater than zero required for word to revert to its initial state.
