3 65
2 80
1 100
2 70
3 40
3 0

#include <iostream>
using namespace std;
int main()
{
    int T;
    cin>>T;
    int arr[T+1]={0},a,b;//这边数组记得加一
    for(int i=0;i<T;i++){
        cin>>a>>b;
        arr[a]+=b;
    }
    int maxNum=0,maxScore=-1;
    for(int i=0;i<T+1;i++){
        if(arr[i]>maxScore) {
            maxNum=i;
            maxScore=arr[i];
        }
    }
    cout<<maxNum<<" "<<maxScore;
    system("pause");
    return 0;
