Given a m x n matrix, if an element was 0, set its entire row and column to 0. Do it on place.Follow up:Did you use extra space?A straight forward solution using O (mn) space is probably a bad idea.A Simple Improvement uses O (m + n) space, but still is not the best solution.Could you devise a constant space solution?public class Solution {public void setzeroes (int[][] matrix) {int m=matrix.length;
