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

Solution:
#include <bits/stdc++.h>
using namespace std;
const int MOD = 1e9 + 7;
const int maxn = 2e5 + 5;
const int inf = 0x3f3f3f3f;
int d[maxn << 1], p[maxn];
int main() {
  int T, n, k;
  scanf("%d", &T);
  while (T--) {
    memset(d, 0, sizeof(d));
    scanf("%d%d", &n, &k);
    for (int i = 1; i <= n; i++) scanf("%d", &p[i]);
    for (int i = 1; i <= n / 2; i++) {
      int sum = p[i] + p[n - i + 1];
      int mi = min(p[i], p[n - i + 1]), mx = max(p[i], p[n - i + 1]);
      d[2] += 2;
      d[mi + 1]--;
      d[mx + k + 1]++;
      d[sum]--;
      d[sum + 1]++;
    }
    int ans = inf, num = 0;
    for (int i = 2; i <= (k << 1); i++) {
      ans = min(ans, num += d[i]);
    }
    printf("%d\n", ans);
  }
  return 0;
