包AC题解(AC不了你顺着网线过来打我)

话不多说上代码

#include <bits/stdc++.h>
using namespace std;
int main(){
    long long n,m,x;
    scanf("%lld",&n);
    scanf("%lld",&m);
    scanf("%lld",&x);
    if(5+n+15<=x)cout<<"on time";
    else if(10+m+15<=x)cout<<"on time";
    else if(17+15<=x)cout<<"on time";
    else cout<<"late";
    return 0;
}
