CF1930B.Permutation Printing
Permutation Printing
You are given a positive integer .
Find a permutation of length such that there do not exist two distinct indices and (; ) such that divides and divides .
Refer to the Notes section for some examples.
Under the constraints of this problem, it can be proven that at least one exists.
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
Each test contains multiple test cases. The first line contains a single integer () — the number of test cases. The description of the test cases follows.
The first line of each test case contains a single integer () — the length of the permutation .
It is guaranteed that the sum of over all test cases does not exceed .
Output
For each test case, output .
If there are multiple solutions, you may output any one of them.
Note
In the first test case, is a valid permutation. However, the permutation is not a valid permutation as we can choose and . Then divides and divides . Note that the permutation is also not a valid permutation as we can choose and . Then divides and divides .
In the second test case, is a valid permutation. In fact, all permutations of length are valid.
