CF2117B.Shrink
Shrink
A shrink operation on an array of size is defined as follows:
- Choose an index () such that and .
- Remove from the array.
Define the score of a permutation as the maximum number of times that you can perform the shrink operation on .
Yousef has given you a single integer . Construct a permutation of length with the maximum possible score. If there are multiple answers, you can output any of them.
A permutation of length is an array consisting of distinct integers from to in arbitrary order. For example, is a permutation, but is not a permutation ( appears twice in the array), and is also not a permutation ( but there is in the array).
Input
The first line of the input contains an integer () — the number of test cases.
Each test case contains an integer () — the size of the permutation.
It is guaranteed that the sum of over all test cases does not exceed .
Output
For each test case, output any permutation that maximizes the number of shrink operations.
Note
In the first test case:
- We choose .
- Choose index , and remove from the array. The array becomes .
It can be shown that the maximum number of operations we can perform is . Another valid answer is .
In the second test case:
- We choose .
- Choose index , and remove from the array. The array becomes .
- Choose index , and remove from the array. The array becomes .
- Choose index , and remove from the array. The array becomes .
- Choose index , and remove from the array. The array becomes .
The maximum number of operations we can perform is . Any permutation with a score of is valid.
