题目 这题不难，但是如果用priority_queue() 做的话就异常的简单。还是分享一下

#define LOCAL
#include<stdio.h>
#include<queue>
#include<iostream>
using namespace std;

int main(){
	#ifdef LOCAL
		freopen("C:/Users/Administrator/Desktop/input.txt","r", stdin);
	#endif
	priority_queue<pair<int, int>, vector<pair<int, int> >, greater<pair<int, int> > > cell;
	int n, a, b;
	while(scanf("%d", &n)!=EOF){
		while(n--){
			scanf("%d%d",&a, &b);
			pair<int, int> c(a, b);
			cell.push(c);
		}
		printf("%d %d\n", cell.top().first, cell.top().second);
		while(!cell.empty()) cell.pop();
	}
	return 0;
}
