改了几次没有效果，测试点情况如下测试点

代码如下

#include<cstdio>
#include<iostream>
using namespace std;
int main(){
	int n,chn[301],math,eng,score[301],sn[301];
	cin>>n;
	for(int i=1;i<=n;i++){
		cin>>chn[i]>>math>>eng;
		score[i]=chn[i]+math+eng;
		sn[i]=i;
	}
	for(int i=1;i<=5;i++){
		for(int j=i+1;j<=n;j++){
			if(score[j]>score[i]){
				int a=score[i];
				score[i]=score[j];
				score[j]=a;
				a=sn[i];
				sn[i]=sn[j];
				sn[j]=a;
			}else if(score[j]==score[i] && chn[j]>chn[i]){
				int a=sn[i];
				sn[i]=sn[j];
				sn[j]=a;
			}else if(score[j]==score[i] && chn[j]==chn[i] && sn[j]<sn[i]){
				int a=sn[i];
				sn[i]=sn[j];
				sn[j]=a;
			}
		} 
	}
	for(int i=1;i<=5;i++){
		cout<<sn[i]<<" "<<score[i]<<endl;
	}
	return 0;
}
