Problem: You are given an array a of length n consisting of zeros. You perform n actions with this array: during the i-th action, the following sequence of operations appears:

  1. Choose the maximum by length subarray (continuous subsegment) consisting only of zeros, among all such segments choose the leftmost one; 
  2. Let this segment be [l; r]. If r-l+1 is odd (not divisible by 2) then assign (set) a[(l+r)/(2)] := i (where i is the number of the current action), otherwise (if r-l+1 is even) assign (set) a[(l+r-1)/(2)] := i. 



Consider the array a of length 5 (initially a=[0, 0, 0, 0, 0]). Then it changes as follows:

  1. Firstly, we choose the segment [1; 5] and assign a[3] := 1, so a becomes [0, 0, 1, 0, 0]; 
  2. then we choose the segment [1; 2] and assign a[1] := 2, so a becomes [2, 0, 1, 0, 0]; 
  3. then we choose the segment [4; 5] and assign a[4] := 3, so a becomes [2, 0, 1, 3, 0]; 
  4. then we choose the segment [2; 2] and assign a[2] := 4, so a becomes [2, 4, 1, 3, 0]; 
  5. and at last we choose the segment [5; 5] and assign a[5] := 5, so a becomes [2, 4, 1, 3, 5]. 



Your task is to find the array a of length n after performing all n actions. Note that the answer exists and unique.

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 (1 ≤ n ≤ 2 ⋅ 10^5) — the length of a.

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 — the array a of length n after performing n actions described in the problem statement. Note that the answer exists and unique.

Solution (in PYTHON3):

Solution:
import heapq
t= int(input())

while t:

	t = t-1
	n = int(input())
	#o(n) time.  #All are zeros
	a = [0]*n
	l = 0
	r = n-1
	mid = int((l+r)/2)
	a[mid] = 1

	li = []
	heapq.heapify(li)
	if mid-l >0:		
		heapq.heappush(li,(-1*(mid-l),l,mid-1))
	if r-mid>0:
		heapq.heappush(li,(-1*(r-mid),mid+1,r))		
	
	for i in range(2,n+1):
		lent, l,r = heapq.heappop(li)
			
		mid = int((l+r)/2)
		a[mid] = i

		if mid-l >0:		
			heapq.heappush(li,(-1*(mid-l),l,mid-1))
		if r-mid>0:
			heapq.heappush(li,(-1*(r-mid),mid+1,r))		
		
	for i in a:
		print(i,end=' ')
	print()
