answer

#include <bits/stdc++.h>
using namespace std;
using i64 = long long;

void solve() {
	int n;
	cin >> n;
	map<string, map<string, int>> cnt1;
	map<string, int> cnt2;
	for (int i = 0 ; i < n ; i++) {
		string a, b, c;
		cin >> a >> b >> c;
		if (c == "accepted") {
			if (!cnt1[a].count(b)) {
				cnt2[b]++;
				cnt1[a][b] = 1;
			}
		}
	}
	int ans = 0;
	for (auto &[x, y] : cnt2) {
		ans = max(ans, y);
	}
	for (auto &[x, y] : cnt2) {
		if (y == ans) {
			cout << x << "\n";
			return;
		}
	}
}

int main() {
	ios::sync_with_stdio(false);
	cin.tie(0);
	cout.tie(0);
	int T;
	cin >> T;
	while (T--) {
		solve();
	}
	return 0;
}

这程序好像有点Bug,我给组数据试试?
