MatrixArray
If any cell of a matrix is 0, set its entire row and its entire column to 0. Zeros created by this process must not cause further zeroing.
Input
Line 1: r and c, the number of rows and columns. Next r lines: c integers each.
Output
Print the resulting matrix, one row per line.
Constraints
1 <= r, c <= 200 -10^9 <= each value <= 10^9
Example 1
Input
3 3 1 1 1 1 0 1 1 1 1
Output
1 0 1 0 0 0 1 0 1
The zero in the middle clears the whole middle row and column.
