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.

Example

Input


5
2

2 4 1 5
NO
YES
2 4 6 8 1 3 5 11
NO

Solution (in CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;
int main() {
  int no_testcases{};
  cin >> no_testcases;
  for (int i{1}; i <= no_testcases; i++) {
    int n{}, sum1{}, sum2{};
    cin >> n;
    int arr[n];
    for (int i = 1; i <= n / 2; i++) {
      arr[i - 1] = 2 * i;
      sum1 = sum1 + (2 * i);
    }
    for (int i{n / 2}, j{1}; i < n - 1; i++, j += 2) {
      arr[i] = j;
      sum2 = sum2 + j;
    }
    if ((sum1 - sum2) % 2 == 0) {
      cout << "NO\n";
    } else {
      arr[n - 1] = sum1 - sum2;
      cout << "YES\n";
      for (int i{}; i < n; i++) {
        cout << arr[i] << " ";
      }
      cout << endl;
    }
  }
  return 0;
