2021 RoboCom World robot developer competition - Semi finals of higher vocational group

Preface

During the competition, the teacher always said , You can't even compete in Higher Vocational Education .

The questions are simple , Just post the code directly .

1. AI says hello

AC Code

#include<bits/stdc++.h>
using namespace std;
#define int long long
int n;
set<string> s;
signed main(){
    
    ios::sync_with_stdio(false),cin.tie(0),cout.tie(0);
    cin>>n;
    while (n--){
    
        string ss;
        cin>>ss;
        if (s.count(ss))
            cout<<"Hi "<<ss<<"! Glad to see you again!\n";
        else
            cout<<"Hello "<<ss<<", how are you?\n",s.insert(ss);
    }
    return 0;
}
