Task 2 Implement a method/function that produces running sum running Sum2 DArray (int[] [] array, int dir) across rows (left to right or right to left) or columns (top to bottom or bottom to top) Input to the method: A 4x4 two dimensional int array and an integer (1, 2, 3 or 4 for left, right, up, down respectively). Output: The modified array after producing the running sums according to the direction. For example: If the input to the method is the same as the earlier array, and if the direction is 2 (right), the output array would be printed as: 25 55 95 1 28 30 ArrayList > list, int dir) that performs the same functionality
