collectionMystery10

Language/Type: C++ collections stack queue STL

Write the output produced by the following function when passed each of the following stacks and ints. Assume that a stack prints in {bottom, ..., top} order, and a queue displays in {front, ..., back} order. 

void collectionMystery10(stack<int>& s, int n) {
    stack<int> s2;
    q<int> q;

    while (s.size() > n) {
        q.push(s.top());
        s.pop();
    }
    while (!s.empty()) {
        int element = s.top();
        s.pop();
        s2.push(element);
        if (element % 2 == 0) {
            q.push(element);
        }
    }
    while (!q.empty()) {
        s.push(q.front());
        q.pop();
    }
    while (!s2.empty()) {
        s.push(s2.top());
        s2.pop();
    }

    cout << s << endl;
}
{1, 2, 3, 4, 5, 6}, n=3
{67, 29, 115, 84, 33, 71, 90}, n=5
