Sakurako's Test
Description
Sakurako will soon take a test. The test can be described as an array of integers $n$ and a task on it:
Given an integer $x$, Sakurako can perform the following operation any number of times:
- Choose an integer $i$ ($1\le i\le n$) such that $a_i\ge x$;
- Change the value of $a_i$ to $a_i-x$.
Using this operation any number of times, she must find the minimum possible median$^{\text{∗}}$ of the array $a$.
Sakurako knows the array but does not know the integer $x$. Someone let it slip that one of the $q$ values of $x$ will be in the next test, so Sakurako is asking you what the answer is for each such $x$.
$^{\text{∗}}$The median of an array of length $n$ is the element that stands in the middle of the sorted array (at the $\frac{n+2}{2}$-th position for even $n$, and at the $\frac{n+1}{2}$-th for odd)
The first line contains one integer $t$ ($1\le t\le 10^4$) — the number of test cases.
The first line of each test case contains two integers $n$ and $q$ ($1\le n,q\le 10^5$) — the number of elements in the array and the number of queries.
The second line of each test case contains $n$ integers $a_1, a_2, \dots, a_n$ ($1\le a_i\le n$) — the elements of the array.
The following $q$ lines each contain one integer $x$ ($1\le x\le n$).
It is guaranteed that the sum of $n$ across all test cases does not exceed $10^5$. The same guarantee applies to the sum of $q$ across all test cases.
For each test case, output $q$ integers — the answer for each query.
Input
The first line contains one integer $t$ ($1\le t\le 10^4$) — the number of test cases.
The first line of each test case contains two integers $n$ and $q$ ($1\le n,q\le 10^5$) — the number of elements in the array and the number of queries.
The second line of each test case contains $n$ integers $a_1, a_2, \dots, a_n$ ($1\le a_i\le n$) — the elements of the array.
The following $q$ lines each contain one integer $x$ ($1\le x\le n$).
It is guaranteed that the sum of $n$ across all test cases does not exceed $10^5$. The same guarantee applies to the sum of $q$ across all test cases.
Output
For each test case, output $q$ integers — the answer for each query.
