3048. Earliest Second to Mark Indices I

You are given two 1-indexed integer arrays, nums and, changeIndices, having lengths n and m, respectively. Initially, all indices in nums are unmarked. Your task is to mark all indices in nums. In each second, s, in order from 1 to m (inclusive), you can perform one of the following operations: - Choose an index i in the range [1, n] and decrement nums[i] by 1. - If nums[changeIndices[s]] is e
