Timur has a stairway with $n$ steps. The $i$-th step is $a_i$ meters higher than its predecessor. The first step is $a_1$ meters higher than the ground, and the ground starts at $0$ meters.

The stairs for the first test case.

Timur has $q$ questions, each denoted by an integer $k_1, \dots, k_q$. For each question $k_i$, you have to print the maximum possible height Timur can achieve by climbing the steps if his legs are of length $k_i$. Timur can only climb the $j$-th step if his legs are of length at least $a_j$. In other words, $k_i \geq a_j$ for each step $j$ climbed.

Note that you should answer each question independently.

The first line contains a single integer $t$ ($1 \leq t \leq 100$) — the number of test cases.

The first line of each test case contains two integers $n, q$ ($1 \leq n, q \leq 2\cdot10^5$) — the number of steps and the number of questions, respectively.

The second line of each test case contains $n$ integers ($1 \leq a_i \leq 10^9$) — the height of the steps.

The third line of each test case contains $q$ integers ($0 \leq k_i \leq 10^9$) — the numbers for each question.

It is guaranteed that the sum of $n$ does not exceed $2\cdot10^5$, and the sum of $q$ does not exceed $2\cdot10^5$.

For each test case, output a single line containing $q$ integers, the answer for each question.

Please note, that the answer for some questions won't fit into 32-bit integer type, so you should use at least 64-bit integer type in your programming language (like long long for C++).
