给大家分享一个无脑45分的（我甚至没打开编译器直接在洛谷平台上写的）

#include <bits/stdc++.h>
using namespace std;

int main(){
    int n,m;
    cin >> n >> m;
    int shit,shit2;
    for (int i =0;i<m;i++){
        cin >> shit >> shit2;
    }
    int q,c,t,a,b;
    cin >> q;
    for (int i = 0;i<q;i++){
        cin >> t;
        if (t == 4 || t == 2){
            cin >> a;
            cout << "NO" << endl;
        }else{
            cin >> a >> b;
            cout << "NO" << endl;
        }
    }
}
