Problem: Set Matrix Zeros

Medium
30 min
Explore how to modify a matrix by setting entire rows and columns to zero when any element is zero. Understand in-place matrix operations and practice efficient traversal methods to solve this common coding interview problem effectively.

Statement

Given a matrix, mat, if any element within the matrix is zero, set that row and column to zero. The performed operations should be in place, i.e., the given matrix is modified directly without allocating another matrix.

Constraints:

  • 11 \le mat.row, mat.col 20\le 20
  • 231-2^{31} \le mat[i][j] 2311\le 2^{31} - 1
