这题是建最小堆，数据结构牛老师讲过这个知识点，但是我给忘了，补题搜了一下才解出来，斯密马噻！！！ 

#include "bits/stdc++.h"
using namespace std;
const int N = 1e4;
int t[N];
int n;
int find(int x){
	for(int i = 1; i <= n; i ++){
		if(t[i] == x) return i;
	}
}
int main(){
	int  m;
	cin>>n>>m;
	for(int i = 1; i <= n; i ++){
		cin>>t[i];
		if(i > 1){
			int tt = i;
			while( tt > 1 && t[tt] < t[tt / 2]){
				swap(t[tt], t[tt / 2]);
				tt /= 2;
			}
		}
	}
	while(m--){
		int x, y;//用于判断的节点 
		string s1, s2, s3,s4;
		cin>>x>>s1;
