Reset Matrix Problem Statement

Given a 2D array ARR with 'N' rows and 'M' columns, where each element is either 0 or 1, your task is to transform this matrix into a 'Good' matrix. A 'Good' matrix is one in which for every 0 found in the matrix, all elements in its row and column are set to 0.

Example:

Input:

ARR = [[1, 0, 1], [1, 1, 1], [1, 1, 1]]

Output:

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

Explanation:

Since ARR[0][1] is 0, all elements in the 0-th row and 1-th column are set to 0.

Constraints:

1 ≤ T ≤ 20

1 ≤ N ≤ 300

1 ≤ M ≤ 300

ARR[i][j] can only be 0 or 1

Note: No need to print the matrix; update the input matrix as per the requirements.

Accepted Answer

Transform a 2D array into a 'Good' matrix by setting rows and columns to 0 if a 0 is found.

Iterate through the matrix to find 0s
For each 0 found, set all elements in its row and column to 0
Update the input matrix accordingly
