Important Messages

문제

These days one may get hundreds of email messages a day. Of course, nobody can read so many of them. Thus Juku wants to highlight messages whose senders are in his contact list.

Write a program that gets Juku's contact list and the senders of his email messages and counts, how many of those messages should be highlighted.

입력

The first line of input contains $NN$, the number of entries in Juku's contact list ($1\le N\le 10001\; \backslash le\; N\; \backslash le\; 1\backslash ,000$), and each of the following $NN$ lines one email address of 1 to 50 characters.

The next line of the file contains $MM$, the number of messages ($1\le M\le 100001\; \backslash le\; M\; \backslash le\; 10\backslash ,000$), and each of the following $MM$ lines the sender address of one message, again 1 to 50 characters.

The characters in an email address can be lower-case letters (a$\dots \backslash dots$z), digits (0$\dots \backslash dots$9), dots (.) and at-signs (@).

출력

The only line of output should contain one integer: the number of messages to be highlighted.
