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 PYTHON3):

Solution:
from collections import defaultdict
for T in range(int(input())) :
    n , k = list(map(int,input().split()))
    arr  = list(map(int,input().split()))

    d = defaultdict(int)
    prefix = [0]*(2*k +2)
    for i in range(n//2) :
        d[arr[i]+ arr[n-1 -i]] +=1
        prefix[min(arr[i],arr[n-i -1])+1] +=1
        prefix[max(arr[i] ,arr[n-i -1]) +k +1] -=1
    mini = float('inf')
    for i in range(2,2*k +2):
        prefix[i] += prefix[i-1]
        
    for i in range(2 ,2*k +2):
        temp = n - prefix[i] - d[i]
        if temp  < mini :
            mini = temp

    print(mini)
