Write a method that inverts a 2D array. Inverting a 2D array means that each row of the 2D array is now a column, and each column is now a row. For example, if we were to invert the 2D array: [1,1,1] [2,2,2] [3,3,3] the result would be: [1,2,3] [1,2,3] [1,2,3] M iii 1 public static int[][] invert(int[][] arr) 2-{ 3 4 } FILES Unit Test Scratchpad.java iii FILES 4 5 6 7 8 9 1- /* This is the Scratchpad! 2 This file is not graded, but you can use it to test your code. 3 You can write and test your method in the Scratchpad, but make sure to copy and paste it into the Unit Test file before check your answer.
