My issue

What wrong in my code?

My code

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

int main() {
	int T;
	cin>>T;
	for(int i = 1; i <= T; i++) {
	   long long int N,M;
	   cin>>N>>M;
	   
	   long long int A[N],B[M];
	   
	   for(int j=0;j<N;j++) {
	       cin>>A[j];
	   }
	   
	   for(int j=0;j<M;j++) {
	       cin>>B[j];
	   }
	   
	   sort(A,A+N,greater<int>());
	   sort(B,B+M,greater<int>());
	   
	  long long int count = 0;
	   
	   if(N >= 4 && M >= 4 && N+M >= 11) {
	       for(int j=0;j<4;j++) {
	           count += (A[j]+B[j]);
	       }
	       
	       vector<long long int>V(11);
	   
	   for(int j=4;j<N;j++) {
	       V.push_back(A[j]);
	   }
	   
	   for(int j=4;j<M;j++) {
	       V.push_back(B[j]);
	   }
	   
	   sort(V.begin(),V.end(),greater<long long int>());
	   
	   int bount = 0;
	   
	   for(int j = 0;j<3;j++) {
	       bount += V[j]; 
	   }
	   
	     cout<<count+bount<<endl;
	   }
	   else {
	       cout<<"-1"<<endl;
	   }
	   
	}
	return 0;
}
