    Stack<int> s;
    int size = q.size();

    for (int i = 0; i < size; i++) {
        int val = q.dequeue();
        if (val < 0) {
            s.push(val);
        } else {
            q.enqueue(val);
        }
    }
    while (!s.isEmpty()) {
        q.enqueue(s.pop());
    }
    cout << q << endl;
}
