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

Solution in JAVA (judge verdict: Wrong Answer)

import java.util.Scanner;
import java.util.Arrays;
import java.util.StringJoiner;

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        
        int sCount = Integer.parseInt(scanner.nextLine());
        String[] s = scanner.nextLine().split(" ");
        
        int tCount = Integer.parseInt(scanner.nextLine());
        String[] t = scanner.nextLine().split(" ");
        
        int count = 0;
        
        for (int i = 0; i < t.length ; i++) {
            for (int j = 0; j < s.length; j++) {
                if (s[j] == t[i]) {
                    count++;
                    break;
                }
            }
        }
        
        System.out.println(count);
