在信息学奥赛一本通过了，到这趴窝了……

代码：

#include<bits/stdc++.h>
using namespace std;
int main(){

	int bu, zuibu = 0, xuexiao, kewai, shijian, lishi = 0;
	
	for(int i = 1; i <= 7; i ++){
		scanf("%d %d",&xuexiao,&kewai);
		if(xuexiao + kewai >= 8){
			shijian = xuexiao + kewai;
			bu = i;
		}
		if(shijian > lishi){
			lishi = shijian;
			zuibu = bu;
		}
		if(shijian == lishi){
			
		}
	}
	
	printf("%d",zuibu);
	
	return 0;
}
