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:
t = int(input())
for _ in range(t):
    n,k = map(int,input().split())
    arr = list(map(int,input().strip().split()))[:n]

    from collections import defaultdict
    store = defaultdict(int)
    limits = [0]*(2*k+2)

    for i in range(n//2):
        a = min(arr[i],arr[n-i-1])+1
        b = max(arr[i],arr[n-i-1])+k

        sims = arr[i]+arr[n-i-1]
        store[sims]+=1

        limits[a] += 1
        limits[b+1] -=1


    for i in range(1,2*k+2):
        limits[i] += limits[i-1]



    ans = float('inf')
    for sums in range(2,2*k+1):
        z_count = store[sums]
        o_count =  limits[sums]-z_count
        t_count = n//2 - z_count - o_count

        
        if ans > t_count*2+o_count:
            ans = t_count*2+o_count

    print(ans)
