Solve the programming task below in a Python markdown code block.
Let f be a [permutation] of length N, where N is even. The *riffle* of f is defined to be the permutation
g = (f(1), f(3), \ldots, f(N-1), f(2), f(4), \ldots, f(N))

You are given two integers N and K. Output the resultant permutation when you riffle the identity permutation of length N, K times.

The identity permutation of length N is {\sigma}_N = (1, 2, \ldots, N)

------ Input Format ------ 

- The first line of input contains a single integer T, denoting the number of test cases. The description of T test cases follows.
- Each test case consists of a single line of input, containing two space-separated integers N and K.

------ Output Format ------ 

For each test case, output the answer permutation as N space-separated integers in a new line.

------ Constraints ------ 

$1 ≤ T ≤ 100$
$1 ≤ N ≤ 3 \cdot 10^{5}$
$1 ≤ K ≤ 10^{9}$
$N$ is even
- The sum of $N$ across test cases does not exceed $3 \cdot 10^{5}$

----- explanation 1 ------ 
Test case $1$: Performing the riffle on $\sigma_{6} = (1, 2, 3, 4, 5, 6)$ once results in $(1, 3, 5, 2, 4, 6)$, by definition.

Test case $2$: The process goes as follows:
- Performing the riffle on $(1, 2, 3, 4, 5, 6, 7, 8)$ results in $(1, 3, 5, 7, 2, 4, 6, 8)$
- Performing the riffle on $(1, 3, 5, 7, 2, 4, 6, 8)$ results in $(1, 5, 2, 6, 3, 7, 4, 8)$
