Consider the following method.

public static void whileMystery(int x, int y) {
    int z = 0;
    while (x < y && z < 4) {
        x = x * 2;
        y = y + 2;
        z++;
    }
    System.out.println(x + " " + y + " " + z);
}

For each call below, indicate what output is produced.

whileMystery(4, 3);
whileMystery(5, 7);
whileMystery(3, 18);
whileMystery(0, 4);
