RedDreamer has an array $a$ consisting of $n$ non-negative integers, and an unlucky integer $T$.

Let's denote the misfortune of array $b$ having length $m$ as $f(b)$ — the number of pairs of integers $(i, j)$ such that $1 \le i \lt j \le m$ and $b_i + b_j = T$. RedDreamer has to paint each element of $a$ into one of two colors, white and black (for each element, the color is chosen independently), and then create two arrays $c$ and $d$ so that all white elements belong to $c$, and all black elements belong to $d$ (it is possible that one of these two arrays becomes empty). RedDreamer wants to paint the elements in such a way that $f(c) + f(d)$ is minimum possible.

For example:

• if $n = 6$, $T = 7$ and $a = [1, 2, 3, 4, 5, 6]$, it is possible to paint the $1$-st, the $4$-th and the $5$-th elements white, and all other elements black. So $c = [1, 4, 5]$, $d = [2, 3, 6]$, and $f(c) + f(d) = 0 + 0 = 0$;
• if $n = 3$, $T = 6$ and $a = [3, 3, 3]$, it is possible to paint the $1$-st element white, and all other elements black. So $c = [3]$, $d = [3, 3]$, and $f(c) + f(d) = 0 + 1 = 1$.

Help RedDreamer to paint the array optimally!

Input

The first line contains one integer $t$ ($1 \le t \le 1000$) — the number of test cases. Then $t$ test cases follow.

The first line of each test case contains two integers $n$ and $T$ ($1 \le n \le 10^5$, $0 \le T \le 10^9$) — the number of elements in the array and the unlucky integer, respectively.

The second line contains $n$ integers $a_1$, $a_2$, ..., $a_n$ ($0 \le a_i \le 10^9$) — the elements of the array.

The sum of $n$ over all test cases does not exceed $10^5$.

Output

For each test case print $n$ integers: $p_1$, $p_2$, ..., $p_n$ (each $p_i$ is either $0$ or $1$) denoting the colors. If $p_i$ is $0$, then $a_i$ is white and belongs to the array $c$, otherwise it is black and belongs to the array $d$.

If there are multiple answers that minimize the value of $f(c) + f(d)$, print any of them.
