rt为什么运行不了（code runner）
只有这一个运行不了，其他的都能运行

以下是我的代码

#include <bits/stdc++.h>
#define int long long

using namespace std;
const int MAXN = 5e7 + 5;
struct node
{
    int num;
    int s;
    bool bj = 0;
    friend bool operator<(const node &a, const node &b)
    {
        if (a.num != b.num)
            return a.num < b.num;
        return a.s < b.s;
    }
    friend bool operator>(const node &a, const node &b)
    {
        if (a.num != b.num)
            return a.num > b.num;
        return a.s > b.s;
    }
};
node msin[MAXN], mcos[MAXN];
int sin_cnt = 1, cos_cnt = 1;

signed main()

    for (int i = 1; i <= n; ++i)
    {
        node x;
        string s;
        int ssin = 0, ccos = 0;
        cin >> s;
        for (int i = 0; i < (int)s.size(); ++i)
        {

                continue;

        }

            cos_cnt++;
            continue;
        }
    }
    sort(msin + 1, msin + sin_cnt, greater<node>());
    sort(mcos + 1, mcos + cos_cnt, greater<node>());
    for (int i = 1; i < sin_cnt; ++i)
        for (int j = 1; j < cos_cnt; ++j)

                continue;
            }
    cout << ans << endl;

    return 0;
