Reverse Rows of a Matrix Problem Statement

You are given a matrix and tasked with reversing the order of elements in each row. This needs to be done for every row in the matrix.

Help a participant named Ninja, who is new to programming, solve this problem by reversing all rows of the given matrix.

Example:

Input:

T = 1
N = 3, M = 3
Matrix:
1 2 3
4 5 6
7 8 9

Output:

3 2 1
6 5 4
9 8 7

Explanation:

Each row of the matrix is reversed, turning [1, 2, 3] into [3, 2, 1], [4, 5, 6] into [6, 5, 4], and [7, 8, 9] into [9, 8, 7].

Constraints:

• 1 <= T <= 50
• 1 <= N <= 400
• 1 <= M <= 400
• 0 <= MAT[i][j] <= 100
• Time Limit: 1 sec
