73. Set Matrix Zeroes

Given a m x n matrix, if an element is 0, set its entire row and column to 0. Do it in place.

public class Solution {
    
    public void setZeroes(int[][] matrix) {
        int m = matrix.length,n = matrix[0].length;
        int k = 0;
        int[][] mark = new int[1000][2];
        for(int i=0;i<1000;i++)
          for(int j=0;j<2;j++)
            mark[i][j] = -1;
        for(int i=0;i<m;i++)
          for(int j=0;j<n;j++)
          {
              if(matrix[i][j]==0)
                 {
                     mark[k][0] = i;
                     mark[k][1] = j;
                     k++;
                 }
          }
        for(int i=0;i<1000;i++)
          {
              if(mark[i][0]!=-1)
                Zeroes(matrix,mark[i][0],mark[i][1]);
          }
    }
    
    public void Zeroes(int[][] a,int row,int col)
    {
        int m = a.length,n = a[0].length;
        for(int i=0;i<n;i++)

        }
