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:
for _ in range(int(input())):
    n, k = [int(s) for s in input().split()]
    arr = [int(s) for s in input().split()]
    f1 = [0]*(2*k+1)
    f2 = [0]*(2*k+1)
    f3 = [0]*(2*k+1)
    for i in range(n//2):
        a = arr[i]
        b = arr[n-i-1]
        f1[a+b]+=1
        f2[max(a,b)+k]+=1
        f3[1+min(a,b)]+=1
    for i in range(2,2*k+1):
        f2[i] += f2[i-1]
        f3[i] += f3[i-1]
    ans = int(1e9)
    for i in range(1,2*k+1):
        ans = min(ans,n//2-f1[i] + f2[i-1] + f3[2*k] - f3[i])
    print(ans)
