Consider the following method:

For each of the following calls, indicate the value that is returned:

a. mystery5(5, 7)

b. mystery5(12, 9)

c. mystery5(-7, 4)

d. mystery5( – 23, –48)

e. mystery5(128, 343)

public static int mystery5 (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;
