题目描述

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, “”, “kulto”, “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.
