My issue

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

int main() {
// your code goes here
int t;
cin>>t;
while(t–) {
int n;
cin >> n;

	if(n/2 % 2 == 0) { 
		cout << "YES\n";
		vector<int>a, b;
		a.push_back(1);
		int i=2, j=0;
		while(i <= n) {
			if(j==0 or j==1) {
				b.push_back(i);
				j++;
			}
			else {
				a.push_back(i);

				if(j == 3) j=0;
				else j++;
			}
			i++;
		}

		for(auto& i : a) {
			cout << i << " ";
		}
		cout << endl;
		for(auto& i : b) {
			cout << i << " ";
		}
		cout << endl;
	}
	else {
		cout << "NO\n";
	}
}
return 0;
