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: Wrong Answer)

import java.util.*;

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