Language/Type: C++ recursion

For each of the calls to the following recursive function below, indicate what output is produced:

void recursionMystery1X(int x, int y) {
    if (y <= 0) {
        cout << "0 ";
    } else if (x > y) {
        cout << x << " ";
        recursionMystery1X(x - y, y);
    } else {
        recursionMystery1X(x, y - x);
        cout << y << " ";
        if (y % 3 == 0) {
            recursionMystery1X(x, y - x);
        }
    }
}

`recursionMystery1X(6, 3);`
`recursionMystery1X(2, 3);`
`recursionMystery1X(5, 8);`
`recursionMystery1X(21, 12);`
`recursionMystery1X(3, 10);`
