Problem Statement

#### For each query find how many words in the dictionary can be matched by the query word ‘W’ by replacing ‘?’(if present) with some lowercase English alphabet.

##### Example :
``````If the dictionary is: {"cat", "rat", "bat", "hat"}

And query words are "?at" and "b?t", then:

"?at" => can be matched by all the 4 dictionary words by replacing '?' with 'c', 'r', 'b' or 'h'.

"b?t" => can only be matched by the dictionary word "bat" by replacing '?' with 'a'.
``````
##### Input Format :
``````The first line contains a single integer ‘T’ denoting the number of test cases. Then each test case follows.

The first line of each test case contains two integers ‘N’ and ‘L’, where N denotes the number of words in the dictionary and L denotes the length of words in the dictionary and queries.

The next line contains N words each of size L, denoting the words in the dictionary.

The next line contains a single integer ‘Q’ denoting the number of queries.

The following Q lines, each contains a word ‘W’ of size L, denoting the query word.
``````
##### Output Format :
``````For each test case print Q integers in a separate line, each denoting the number of dictionary words that can be matched by the query word.

Output for each test case will be printed in a separate line.
``````
##### Note :
``````You are not required to print anything; it has already been taken care of. Just implement the function.
``````
##### Constraints :
``````1 <= T <= 10
1 <= N <= 100
1 <= L <= 7
1 <= Q <= 100
1 <= word.size <= L

Time limit: 1 sec

##### Explanation Of Sample Output 1 :
``````For test case 1 :
Query1: “?at” matches with “cat” and “bat”
Query2: “ma?” matches with “map” and “man”
Query3: “?a?” matches with “cat”, “bat”, “map” and “man”
Query4: “??n” matches with “man” and “pen”

For test case 2 :
Query1: “bbbbb” doesn’t matches with any dictionary words
