Problem: Find the intersection of two sets $A = \\{a_0, a_1, ..., a_{n-1}\\}$ and $B = \\{b_0, b_1, ..., b_{m-1}\\}$.

Constraints

* $1 \leq n, m \leq 200,000$
* $0 \leq a_0 < a_1 < ... < a_{n-1} \leq 10^9$
* $0 \leq b_0 < b_1 < ... < b_{m-1} \leq 10^9$

Input

The input is given in the following format.


$n$
$a_0 \; a_1 \; ... \; a_{n-1}$
$m$
$b_0 \; b_1 \; ... \; b_{m-1}$


Elements of $A$ and $B$ are given in ascending order respectively. There are no duplicate elements in each set.

Output

Print elements in the intersection in ascending order. Print an element in a line.

Example

Input

4
1 2 5 8
5
2 3 5 9 11


Output

2
5

Solution (in JAVA):

Solution:
import java.util.Scanner;
import java.util.TreeSet;

public class Main {
	public static void main(String args[]) {

		Scanner scan = new Scanner (System.in);
		
		//list作成
		TreeSet<Integer> set = new TreeSet<>();
		
		int a = scan.nextInt();
		for(int i=0; i<a; i++) {
			int num = scan.nextInt();
			set.add(num);
		}
		
		//list2作成
		TreeSet<Integer> set2 = new TreeSet<>();
		
		int b = scan.nextInt();
		for(int i=0; i<b; i++) {
			int num = scan.nextInt();
			set2.add(num);
		}
		
		//積集合
		TreeSet<Integer> intersection = new TreeSet<>(set);
		intersection.retainAll(set2);
		
//		System.out.println("dubug");
//		System.out.println(intersection.size());
		
		for(int i : intersection) {
			System.out.println(i);
		}
