2946. Matrix Similarity After Cyclic Shifts

You are given an m x n integer matrix mat and an integer k. The matrix rows are 0-indexed. The following proccess happens k times: - Even-indexed rows (0, 2, 4, ...) are cyclically shifted to the left. - Odd-indexed rows (1, 3, 5, ...) are cyclically shifted to the right. Return true if the final modified matrix after k steps is identical to the original matrix, and false otherwise. Example
