The only difference between this problem and the hard version is the constraints on $t$ and $n$.

You are given an array of $n$ positive integers $a_1,\dots,a_n$, and a (possibly negative) integer $c$.

Across all permutations $b_1,\dots,b_n$ of the array $a_1,\dots,a_n$, consider the minimum possible value of $$\sum_{i=1}^{n-1} |b_{i+1}-b_i-c|.$$ Find the lexicographically smallest permutation $b$ of the array $a$ that achieves this minimum.

A sequence $x$ is lexicographically smaller than a sequence $y$ if and only if one of the following holds:

• $x$ is a prefix of $y$, but $x \ne y$;
• in the first position where $x$ and $y$ differ, the sequence $x$ has a smaller element than the corresponding element in $y$.

Each test contains multiple test cases. The first line contains the number of test cases $t$ ($1 \le t \le 10^3$). The description of the test cases follows.

The first line of each test case contains two integers $n$ and $c$ ($1 \le n \le 5 \cdot 10^3$, $-10^9 \le c \le 10^9$).

The second line of each test case contains $n$ integers $a_1,\dots,a_n$ ($1 \le a_i \le 10^9$).

It is guaranteed that the sum of $n$ over all test cases does not exceed $5 \cdot 10^3$.

For each test case, output $n$ integers $b_1,\dots,b_n$, the lexicographically smallest permutation of $a$ that achieves the minimum $\sum\limits_{i=1}^{n-1} |b_{i+1}-b_i-c|$.
