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.
The first line of input contains $N,ドル the number of entries in Juku's contact list (1ドル \le N \le 1,000円$), and each of the following $N$ lines one email address of 1 to 50 characters.
The next line of the file contains $M,ドル the number of messages (1ドル \le M \le 10,000円$), and each of the following $M$ lines the sender address of one message, again 1 to 50 characters.
The characters in an email address can be lower-case letters (a$\dots$z), digits (0$\dots$9), dots (.) and at-signs (@).
The only line of output should contain one integer: the number of messages to be highlighted.
