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: Accepted)

import java.io.IOException;
import java.util.*;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int n = Integer.parseInt(sc.nextLine()); //数列Sの長さ
        String[] s = sc.nextLine().split(" "); //数列S

        int q = Integer.parseInt(sc.nextLine()); //数列Tの長さ
        String[] t = sc.nextLine().split(" "); //数列T

        int count = 0; //出力結果（個数）
        for(int j=0; j<q; j++) {
            for(int i=0; i<n; i++) {
                if(s[i].equals(t[j])){
                    count++;
                    break; 
                }
            }
        }
        System.out.println(count);
    }
