My wrong code:

#include <bits/stdc++.h>
using namespace std;
stack<int>s;
int psd[100005],ppd[100005],q,n,x;
int main(){
	ios::sync_with_stdio(0);
	cin.tie(0);
	cin>>q;
	for(int i=1;i<=q;i++){
		cin>>n;
		for(int j=1;j<=n;j++) cin>>psd[j];
		for(int j=1;j<=n;j++) cin>>ppd[j];
		x=1;
		for(int j=1;j<=n;j++){
			s.push(psd[j]);
			while(!s.empty()&&s.top()==ppd[x]){
				s.pop();
				x++;
			}
		}
		if(s.empty()) cout<<"YES\n";
		else cout<<"NO\n";
		while(!s.empty()) s.pop();
	}
	return 0;
}

HELP ME!!!
