array2D_storageSpace


Given a 2D array of integers (1D arrays to build a 2D array from), return the total number of integers that the 2D array can store. Your first line of code must be: 

int[][] arr = {row1, row2, row3};

array2D_storageSpace([1, 1], [2, 2], [3, 3]) → 6
array2D_storageSpace([1, 2, 3], [4, 5, 6], [7, 8, 9]) → 9
array2D_storageSpace([1], [2], [3]) → 3

...Save, Compile, Run (ctrl-enter)

public int array2D_storageSpace(int[] row1, int[] row2, int[] row3) { }
