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:
from sys import stdin

    return stdin.buffer.readline().rstrip().decode("utf8")


def itg():
    return int(stdin.buffer.readline())


def mpint():
    return map(int, stdin.buffer.readline().split())

for case in range(itg()):
    n, k = mpint()
    arr = tuple(mpint())
    cnt = [0] * (2*k + 7)
    cnt[0] = n
    for i in range(n >> 1):
        a, b = arr[i], arr[-i-1]
        mn = min(a, b) + 1
        mx = max(a, b) + k
        # [mn,a+b): -1, a+b:-2, (a+b,mx]:-1
        cnt[mn] -= 1
        cnt[a+b] -= 1
        cnt[a+b+1] += 1
        cnt[mx+1] += 1

    ans = n
    for i in range(1, len(cnt)):
        cnt[i] += cnt[i-1]
        ans = min(ans, cnt[i])

    print(ans)
