Set Matrix Zeroes

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

Output matrix rows, space-separated.

Input:

1,1,1
1,0,1
1,1,1

Output:

1 0 1
0 0 0
1 0 1

Reasoning:

The input matrix is: 1 1 1 1 0 1 1 1 1
We identify the rows and columns that contain a 0, which are row 2 and column 2.
We set the entire row 2 to 0 and the entire column 2 to 0, resulting in: 1 0 1 0 0 0 1 0 1
The final output is the modified matrix, with the specified rows and columns set to 0.
