Matrix Similarity After Cyclic Shifts

Description

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.
