Matrix Bit Flipping Problem

In this task, you're provided with a binary square matrix of size 'N * N' named MAT. The task requires you to perform row and column flips whenever a zero (0) is encountered in the matrix. Specifically, for any position (i, j) where MAT[i][j] is 0, flip all 1s located in the ith row and the jth column of the matrix.

Your Objective:

Return the total count of these flipping operations across the entire matrix.

Example:

Input:

T = 1
N = 3
MAT = [[0, 1, 1],
[1, 1, 1],
[1, 0, 1]]

Output:

6

Explanation:

Considering the matrix above, when we encounter a 0, the 1s in that row or column are flipped, yielding a total of 6 flips as shown in the images.

Constraints:

1 ≤ T ≤ 5

0 ≤ N ≤ 100

MAT[i][j] is either 0 or 1.

For each zero, flips are only counted in its initial state, not the state after any flips.

Note:

You only need to implement the solution function, as printing the output is handled elsewhere.

Accepted Answer

Count the total number of flips required in a binary matrix when encountering zeros.

Iterate through the matrix and whenever a zero is encountered, flip all 1s in the corresponding row and column.
Keep track of the total number of flips required.
Return the total count of flips at the end.
