public static boolean equals(int[][] m1, int[][] m2)

when calling the method equals m1 and m2 should not change.

Sorting the arrays makes the solution not efficient.

Creating equivalent single dimensional arrays is also not efficient.

Java

The two-dimensional arrays mi and m2 are identical if they have the same contents. Write a method that returns true if mi and m2 are identical, using the following header: public static boolean equals(int[][] ml, int[][] m2) Write a test program that prompts the user to enter two 3 * 3 arrays of integers and displays whether the two arrays are identical. Here are the sample runs: Enter m1: 51 25 22 6 1 4 24 54 6 Enter m2: 51 22 25 6 1 24 4 54 6 The two arrays are identical. Enter ml: 51 5 22 6 14 24 54 6 Enter m2: 51 22 25 6 1 4 24 54 6 The two arrays are not identical
