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;
  while (t--) {
    int n, k;
    cin >> n >> k;
    vector<int> a(n);
    for (int i = 0; i < n; i++) cin >> a[i];
    map<int, int> sum;
    vector<int> up;
    vector<int> lb;
    for (int i = 0; i < n / 2; i++) {
      up.push_back(max(a[i] + k, a[n - i - 1] + k));
      lb.push_back(min(a[i] + 1, a[n - i - 1] + 1));
      sum[a[i] + a[n - i - 1]]++;
    }
    sort(up.begin(), up.end());
    sort(lb.begin(), lb.end());
    int ans = INT_MAX;
    for (int i = 1; i <= 2 * k; i++) {
      int s = i;
      int pre = sum[i];
      int crt1 = lower_bound(up.begin(), up.end(), s) - up.begin();
      int crt2 = lb.end() - lower_bound(lb.begin(), lb.end(), s + 1);
      int curr = crt1 + crt2 + (n / 2 - pre);
      ans = min(ans, curr);
    }
    cout << ans << "\n";
  }
