Problem: You are given a positive integer n, it is guaranteed that n is even (i.e. divisible by 2).

You want to construct the array a of length n such that: 

  * The first n/2 elements of a are even (divisible by 2); 
  * the second n/2 elements of a are odd (not divisible by 2); 
  * all elements of a are distinct and positive; 
  * the sum of the first half equals to the sum of the second half (∑_{i=1}^{n/2} a_i = ∑_{i=n/2 + 1}^{n} a_i). 



If there are multiple answers, you can print any. It is not guaranteed that the answer exists.

You have to answer t independent test cases.

Input

The first line of the input contains one integer t (1 ≤ t ≤ 10^4) — the number of test cases. Then t test cases follow.

The only line of the test case contains one integer n (2 ≤ n ≤ 2 ⋅ 10^5) — the length of the array. It is guaranteed that that n is even (i.e. divisible by 2).

It is guaranteed that the sum of n over all test cases does not exceed 2 ⋅ 10^5 (∑ n ≤ 2 ⋅ 10^5).

Output

For each test case, print the answer — "NO" (without quotes), if there is no suitable answer for the given test case or "YES" in the first line and any suitable array a_1, a_2, ..., a_n (1 ≤ a_i ≤ 10^9) satisfying conditions from the problem statement on the second line.

Solution (in CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;
int main() {
  int t;
  cin >> t;
  int a[100000];
  while (t--) {
    int n;
    cin >> n;
    int k = 1, l = 2;
    int sum = 0, sum1 = 0;
    if ((n / 2) % 2 != 0)
      cout << "NO\n";
    else {
      cout << "YES\n";
      for (int i = 0; i < n / 2; i++) {
        a[i] = l;
        l = l + 2;
        sum1 = sum1 + a[i];
        cout << a[i] << " ";
      }
      for (int i = n / 2; i < n - 1; i++) {
        a[i] = k;
        sum = sum + a[i];
        k = k + 2;
        cout << a[i] << " ";
      }
      int u = sum1 - sum;
      cout << u << "\n";
    }
  }
