Set Matrix Zeroes Leetcode August day 13 solution

Given an m x n integer matrix matrix, if an element is 0, set its entire row and column to 0's, and return the matrix. You must do it in place. Example 1: Input: matrix = [[1,1,1],[1,0,1],[1,1,1]] Output: [[1,0,1],[0,0,0],[1,0,1]] Example 2: Input: matrix = [[0,1,2,0],[3,4,5,2],[1,3,1,5]] Output: [[0,0,0,0],[0,4,5,0],[0,3,1,0]] Constraints: m == matrix.length n == matrix[0].length 1 <= m, n <= 200 -231 <= matrix[i][j] <= 231 - 1 Follow up: A straightforward solution using O(mn) space is probably a bad idea. A simple improvement uses O(m + n) space, but still not the best solution. Could you devise a constant space solution?
