Problem:
Search I

You are given a sequence of n integers S and a sequence of different q integers T. Write a program which outputs C, the number of integers in T which are also in the set S.

Input

In the first line n is given. In the second line, n integers are given. In the third line q is given. Then, in the fourth line, q integers are given.

Output

Print C in a line.

Constraints

n ≤ 10000

q ≤ 500

0 ≤ an element in S ≤ 109

0 ≤ an element in T ≤ 109

Notes

Solution in JAVA (judge verdict: Accepted)

import java.util.*;

public class Main{
    public static void main(String[] args){
        Scanner sc = new Scanner(System.in);
        ArrayList<Integer> S = new ArrayList<Integer>();
        int n = sc.nextInt();
        
        for(int i = 0;i<n;i++ ){
            S.add(sc.nextInt());
        }
        int cnt = 0;
        int q = sc.nextInt();
        for(int i = 0;i<q;i++ ){
            int num = sc.nextInt();
            if(S.contains(num))cnt++;
        }
        System.out.println(cnt);
        
    }
}
