문제

The cows are trying out a new method of exchanging coded messages with each-other where they mix irrelevant letters in among relevant letters to make the messages hard to decode.

The cows transmit two strings ss and tt each of length at most 10510^5 consisting only of the lowercase English letters 'a' through 'r'. To try and make sense of this coded message, you will be given QQ queries (1≤Q≤1051 \leq Q \leq 10^5). Each query provides a subset of the lowercase English letters from 'a' to 'r.' You need to determine for each query whether ss and tt, when restricted only to the letters in the query, are equal.

입력

First line contains ss.

Second line contains tt.

Third line contains QQ.

Next QQ lines each contain a query string. Within a query string, no letters are repeated. Furthermore, all query strings are in sorted order, and no query string appears more than once.

출력

For each query, print 'Y' if ss and tt, when restricted only to the letters in the query, are equal, or 'N' otherwise.

힌트

For the first query, both strings become "aa" when restricted only to 'a.'

For the second query, the first string becomes "aac" while the second string becomes "caa."
