用set就行了。

#include <bits/stdc++.h>
using namespace std;
int main() {
    freopen("set.in","r",stdin);
    freopen("set.out","w",stdout);
    int t,n;
    cin>>t;
    for (int i = 0; i < t; i++) {
        cin>>n;
        set<int> a;
        set<int> b;
        for (int j = 0; j < n; j++) {
            int x;
            cin>>x;
            a.insert(x);
        }
        for (int j = 0; j < n; j++) {
            int x;
            cin>>x;
            b.insert(x);
        }
        if (a == b) {
            cout<<"yes"<<endl;
        } else {
            cout<<"no"<<endl;
        }
    }
    return 0;
}
