My main method:

public static void main(String[] args) {

Scanner scanner = new Scanner(System.in);

// input arrays with ";" between them

String[] temp = scanner.nextLine().split(";");

// input integers with white space between them

int[][] arr = new int[4][4];

for (int i = 0; i

String[] tempA = temp[i].split("s");

for (int j = 0; j

arr[i][j] = Integer.parseInt(tempA[j]);

}

}

// input integers with white space between them

ArrayList> list = new ArrayList>();

for (int i = 0; i

String[] tempA = temp[i].split("s");

list.add(i, new ArrayList());

for (int j = 0; j

list.get(i).add(j, Integer.parseInt(tempA[j]));

}

}

runningSum2DArray(arr, 1);

runningSum2DArray(arr, 2);

// runningSum2DArrayList(list, 3);

// runningSum2DArrayList(list, 4);

scanner.close();

}

Task 2 Implement a method/function that produces running sum runningSum2DArray (intll] 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: 10 15 20 25 28 26 10 95 30 28 10 20 Now, Implement another function runningSum2DArrayList (ArrayList > list, int dir) that performs the same functionality.
