        pq.pop();

        int tmp = p.s % 2;
        if (!tmp) {
            auto nw = coin(p.s  * p.c, 1);
            pq.push(nw);
        } else {
            auto nw = coin((p.s - 2) * p.c, 1);
            pq.push(nw);
        }
    }
    int ans = 0;
    while (!pq.empty()) {
        cout << pq.top().c << " " << pq.top().s << endl;
        ans += pq.top().s;
        pq.pop();

    }
    cout << ans;
    return 0;
}

为什么 pq.push(coin(c, s)); 会报错，怎么让他不爆错。
