Given the following method:

public static void whileMystery(int x, int y) {
    int s = 0;

    while (x > 0 && 2 * y >= x) {
        System.out.print(s + " ");
        y = y - x;
        x--;
        s = s + x;
    }

    System.out.println(s);
}

Write the output of each of the following calls.

whileMystery(-2, -6);
whileMystery(2, 3);
whileMystery(4, 8);
whileMystery(5, 40);
whileMystery(10, 31);
