This task is inspired by the recent MH370 stolen passport incident.

The Interpol database contains a list of N stolen passport numbers. We have another list of M passport numbers to check if they are stolen or not.

• The first line of the input contains an integer N. (1 ≤ N ≤ 100,000)
• The next N lines contains the list of N stolen passport numbers, one passport number per line.
• The next line of the input contains an integer M. (1 ≤ M ≤ 100,000)
• The next M lines contains the list of M passport numbers, one passport number per line.

Passport numbers are alphanumeric (combination of alphabetic and numeric characters) and are of length at most 15

Output the total number of stolen passports in the list of M passports.
