题目：

sort排序：

#include<iostream>
#include<algorithm>
using namespace std;
#define M 100005
//int a[M];struct person
{int num;int c,m,e;int sum;
}a[M];bool cmp(person p1,person p2)
{if(p1.sum!=p2.sum){return p1.sum>p2.sum;}else{if(p1.c!=p2.c){return p1.c>p2.c;}else{return p1.num<p2.num;}}
}int main()
{int n;cin>>n;for(int i=1;i<=n;i++){cin>>a[i].c>>a[i].m>>a[i].e;a[i].sum=a[i].c+a[i].m+a[i].e;a[i].num=i;}sort(a+1,a+n+1,cmp);for(int i=1;i<=5;i++){cout<<a[i].num<<" "<<a[i].sum<<endl;}
}
