Problem AK
Oop

Little Matej is solving an OOP (Object-oriented programming) laboratory exercise and he’s having trouble with solving one subtask.

He is given a set that contains $N$ words. He is also given $Q$ queries where each query is one pattern. A pattern consists of a single character “*” and lowercase letters of the English alphabet. For example, “*”, “kul*to”, “ana*”.

A pattern is said to cover a word if such an array of letters (which can be empty) exists that, when replacing the character “*”, the pattern and the word become completely identical. It is necessary to output how many words each pattern covers.

Input

The first line of input contains two integers $N$ and $Q$ ($1 \leq N, Q \leq 100\, 000$). Each of the following $N$ lines contains a word that consists of lowercase letters of the English alphabet. Each of the following $Q$ lines contains a pattern for which you need to output how many words from the first set it covers. The total number of characters will be less than $4\, 000\, 000$.

Output

Output $Q$ lines, the $k$-th line containing the number of words that the $k$-th pattern covers.
