#### Mirror Of Matrix

d
```package com.thealgorithms.misc;

// Problem Statement
/*
We have given an array of m x n (where m is the number of rows and n is the number of columns).
Print the new matrix in such a way that the new matrix is the mirror image of the original matrix.

The Original matrix is:   |   The Mirror matrix is:
1	2	3	              |   3	 2	 1
4	5	6	              |   6	 5	 4
7	8	9	              |   9	 8	 7
