Problem: Set Matrix Zeros

Medium
30 min
Understand how to solve matrix modification problems by setting rows and columns to zero when any element is zero. Explore in-place operations and efficient traversal to optimize coding interview solutions for matrices.

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
