Problem statement :

  • Given an m x n integer matrix matrix, if an element is 0, set its entire row and column to 0's.
    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]]

Explanation :

from:

[[ 1 , 1 , 1],
 [ 1 , 0 , 1],
 [ 1 , 1 , 1]] 

to:

[[ 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]]

Explanation:

from:

[[ 0 , 1 , 2 , 0 ],
 [ 3 , 4 , 5 , 2 ],
 [ 1 , 3 , 1 , 5 ]]

to:

[[ 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

This problem covers topics like Arrays, Hash Table and Matrix.
