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

Input


5
2
4
6

Output


NO
YES
2 4 1 5
NO
YES
2 4 6 8 1 3 5 11
NO

Solution (in PYTHON3):

Solution:
testCases = int(input())
while testCases > 0:
    n, k = map(int, input().split())
    a = list(map(int, input().split()))[:n]

    opened, closed, exist = {}, {}, {}
    for i in range(2*k + 1):
        opened[i] = closed[i] = exist[i] = 0

    for i in range(int(n / 2)):
        L, R = a[i], a[n - 1 - i]
        exist[L + R] += 1
        opened[1 + min(L, R)] += 1
        closed[k + max(L, R)] += 1

    Answer, inside = 10**9, 0
    for i in range(2*k + 1):
        inside += opened[i]
        Answer = min(Answer, n - exist[i] - inside)
        inside -= closed[i]

    print(Answer)
    testCases -= 1
