You are given an array a of length n, consisting of positive integers, and an array x of length q, also consisting of positive integers.
There are q modification. On the i-th modification (1≤i≤q), for each j (1≤j≤n), such that aj is divisible by 2xi, you add 2xi−1 to aj. Note that xi (1≤xi≤30) is a positive integer not exceeding 30.
After all modification queries, you need to output the final array.
Input
The first line contains a single integer t (1≤t≤104) --- the number of test cases. The description of the test cases follows.
The first line of each test case contains two integers n and q (1≤n,q≤105) ---the length of the array a and the number of queries respectively.
The second line of each test case contains n integers a1,a2,a3,...,an --- the elements of the array a (1≤ai≤109).
The third line of each test case contains q integers x1,x2,x3,...,xq --- the elements of the array x (1≤xi≤30), which are the modification queries.
It is guaranteed that the sum of n and the sum of q across all test cases does not exceed 2⋅105.
Output
For each test case, output the array after all of the modification queries.

Note
In the first test case, the first query will add 2 to the integers in positions 4 and 5. After this addition, the array would be 1,2,3,6,6. Other operations will not modify the array.
In the second test case, the first modification query does not change the array. The second modification query will add 8 to the integer in position 5, so that the array would look like this: 7,8,12,36,56,6,3. The third modification query will add 2 to the integers in positions 2,3, 4 and 5. The array would then look like this: 7,10,14,38,58,6,3.

解题说明:此题是一道模拟题,给定一个数组 arr 和一组指数 t,按照从小到大的顺序,对数组中能被 2^t 整除的元素,加上 2^(t-1)。每个指数最多使用一次,且一旦使用到最小值就停止。对每个指数 t[j],检查数组元素 arr[k] 是否能被 2^t[j] 整除,如果能整除,则加上 2^(t[j]-1)。
