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

Solution:
import java.util.Scanner;
import java.util.Set;
import java.util.TreeSet;
class Main {
	public static void main(String[] args) {
		try(Scanner sc = new Scanner(System.in)){
			int n = sc.nextInt();
			Set<Integer> a = new TreeSet<>();
			for(int i = 0; i < n; i++) {
				a.add(sc.nextInt());
			}
			int m = sc.nextInt();
			Set<Integer> b = new TreeSet<>();
			for(int i = 0; i < m; i++) {
				b.add(sc.nextInt());
			}

			a.removeIf((num) -> !b.contains(num));
			a.forEach(num -> System.out.println(num));
		}
