You are given two arrays $a$ and $b$ of size $n$. The beauty of the arrays $a$ and $b$ is the number of indices $i$ such that $a_i \gt b_i$.

翻译中…

You are also given an integer $x$. Determine whether it is possible to rearrange the elements of $b$ such that the beauty of the arrays becomes $x$. If it is possible, output one valid rearrangement of $b$.

Input

翻译中…

Each test contains multiple test cases. The first line contains the number of test cases $t$ ($1 \le t \le 10^4$). The description of the test cases follows.

翻译中…

The first line of each test case contains two integers $n$ and $x$ ($1 \le n \le 2\cdot 10^5$, $0 \le x \le n$) — the size of arrays $a$ and $b$ and the desired beauty of the arrays.

翻译中…

The second line of each test case contains $n$ integers $a_1, a_2, \ldots, a_n$ ($1 \le a_i \le 2n$) — the elements of array $a$.

翻译中…

The third line of each test case contains $n$ integers $b_1, b_2, \ldots, b_n$ ($1 \le b_i \le 2n$) — the elements of array $b$.

翻译中…

It is guaranteed that the sum of $n$ over all test cases does not exceed $2\cdot 10^5$.

翻译中…

Output

翻译中…

For each test case, output "NO" if it is not possible to rearrange $b$ to make the beauty of the arrays equal to $x$.

翻译中…

Otherwise, output "YES". Then, on the next line, output $n$ integers which represent the rearrangement of $b$.

翻译中…

If there are multiple solutions, you may output any of them.

翻译中…

You can output "YES" and "NO" in any case (upper or lower). For example, the strings "yEs", "yes", "Yes", and "YES" will be recognized as positive responses.

翻译中…

Note

翻译中…

In test cases 1 and 2, the beauty of the arrays has to be $0$ since $a_1 = 1 \le 2 = b_1$.

翻译中…

In test cases 3, 4, 5 and 6, the only possible beauty of the arrays is $x = 1$ and $x = 2$. In particular, if $b$ is rearranged to $[2, 4, 1]$, then $a_3 = 3 \gt 1 = b_3$, so the beauty of the arrays is $1$. If $b$ is kept in the same order as given the input, then $a_2 = 4 \gt b_2 = 1$ and $a_3 = 3 \gt 2 = b_3$, so the beauty of the arrays is $2$.
