只用cin就够了

桶排序

#include <bits/stdc++.h>
using namespace std;
int main(){
    long long n,p[3]={0};
    char ch;
    cin>>n;
    while(cin>>ch) p[ch-'A']++;
    if(p[0]>p[1]){
        if(p[0]>p[2]) cout<<"human";
        else cout<<"saiyan";
    }
    else{
        if(p[1]>p[2]) cout<<"puppy";
        else cout<<"saiyan";
    }
    return 0;
}
