Write a method that takes a 2D array and reverses all of the content in the 2D array. The last value should be the first, and the first value should be the last. For example, the call reverse({{1,2,3},{4,5,6},{7,8,9}}) would return: [9,8,7] [6,5,4] [3,2,1] M iii 1 public static int[][] reverse(int[][] arr) 2-{ 3 4 } 5 FILES Scratchpad.java Unit Test M iii FILES 1- /* This is the Scratchpad! 2 This file is not graded, but you can use it to test your code. 3 4 You can write and test your method in the Scratchpad, but make 5 sure to copy and paste it into the Unit Test file before check 6 your answer. Remember to only copy and paste the method you wa 7 to submit, not all of your tests.
