Description:

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.

$\text{[math]}$ 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.

Input:

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 $$$2\cdot10^5$$$.

Output:

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++).

Sample Input:

3
4 5
1 2 1 5
1 2 4 9 10
2 2
1 1
0 1
3 1
1000000000 1000000000 1000000000
1000000000

Sample Output:

1 4 4 9 9 
0 2 
3000000000

Note:

Consider the first test case, pictured in the statement.

If Timur's legs have length $$$1$$$, then he can only climb stair $$$1$$$, so the highest he can reach is $$$1$$$ meter.
If Timur's legs have length $$$2$$$ or $$$4$$$, then he can only climb stairs $$$1$$$, $$$2$$$, and $$$3$$$, so the highest he can reach is $$$1+2+1=4$$$ meters.
If Timur's legs have length $$$9$$$ or $$$10$$$, then he can climb the whole staircase, so the highest he can reach is $$$1+2+1+5=9$$$ meters.

In the first question of the second test case, Timur has no legs, so he cannot go up even a single step. :(
