#include <bits/stdc++.h>

using i64 = long long;

void solve() {
	int n;
	std::cin >> n;

	std::vector<int> f(26);
	std::set<std::string> s;
	for (int i = 1; i <= n; i++) {
		std::string a, c;
		char b;
		std::cin >> a >> b >> c;
		if (c == "accepted") {
			if (!s.count(a)) {
				f[b - 'A']++;
				s.insert(a);
			}
		}
	}

	char ans;
	int max = -1;
	for (int i = 0; i < 26; i++) {
		if (f[i] > max) {
			max = f[i];
			ans = i + 'A';

	}

	std::cout << ans << '\n';
}

int main() {
	std::ios::sync_with_stdio(false);
	std::cin.tie(nullptr);

	int t = 1;
	std::cin >> t;

	while (t--) {
