class RecentCounter {
public:
    RecentCounter() {
    }
    
    int ping(int t) {
        while (!q.empty()) {
            if (q.front() >= (t - 3000)) {
                break;
            }
            q.pop();
        }
        q.push(t);

        return q.size();
    }

private:
    queue<int> q;
};

/**
 * Your RecentCounter object will be instantiated and called as such:
 * RecentCounter* obj = new RecentCounter();
 * int param_1 = obj->ping(t);
