样例过了，下载了数据发现输出一样

#include<bits/stdc++.h>
using namespace std;
int main(){
	priority_queue<int> p;
	priority_queue<int,vector<int>,greater<int> > q;
	int n,x,y,m;
	cin>>n>>x;
	p.push(x);
	for(int i=2;i<=n;i+=2){
		m=p.top();
		cout<<m<<endl;
		cin>>x>>y;
		if(x>y)swap(x,y);
		if(m<=x){
			q.push(x);
			q.push(y);
			p.push(q.top());
			q.pop();
		}
		else if(y<=m){

			p.push(y);
			q.push(p.top());
			p.pop();
		}
		else{
			p.push(x);
			q.push(y);

	}
	cout<<p.top();
	return 0;
