For each call to the following method, indicate what value is returned: public int mystery 5 (int x, int y) { if (x < 0) { return -mystery5(-x, y); } else if (y < 0) { return -mystery5(x, y); } else if (x == 0 && y == 0) { return 0; } else { } return 100 * mystery5 (x / 10, y / 10) + 10* (x % 10) + y % 10; } mystery5(5, 7) mystery5 (12, 9) mystery5(-7, 4) mystery5(-23, -48) mystery5 (128, 343)
