안녕하세요 제 코드에 반례가 있을까요?

문제를 풀어서 보여지는 테스트 케이스는 다 맞는데 반례가 있을까요?

#include <bits/stdc++.h>

int n;
int temp;

    cin.tie(NULL);
    cout.tie(NULL);
    cin >> n;
    for(int i = 0; i < n; i++){
        cin >> temp >> mmss;
        string m = mmss.substr(0,2);
        string s = mmss.substr(3,2);
        int mm = atoi(m.c_str());

        int ss = atoi(s.c_str()) + 60*mm;

        if(team1.first == team2.first){
            if(temp == 1){
                team1.first++;
