#include <bits/stdc++.h>

using namespace std;

int main()

{

int n,x;

int a,b,c,f[101];

int j,i;

cin>>n;

for(i=1;i<=n;i++)

{

cin>>x;

for(j=1;j<=x;j++)

{

cin>>a>>b;

f[j]=a*60+b;

c+=a*60+b;

}

sort(f,f+j+1);

cout<<"Track "<<i<<":"<<endl;

cout<<"Best Lap: "<<f[1]/60<<" minute(s) "<<f[1]%60<<" second(s)."<<endl;

cout<<"Average: "<<(c/x)/60<<" minute(s) "<<(c/x)%60<<" second(s)."<<endl<<endl;

c=0;

}

}

我在電腦測試正常，答案也沒錯。

貼到這邊就變成 Average 0 minute(s) 0 second(s)  (╯◕ヮ◕)╯︵┻━┻
