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

	public static void main(String[] args) {
		// TODO 自動生成されたメソッド・スタブ
		Scanner sc = new Scanner(System.in);
		Set<Integer> setA = new TreeSet<>();
		Set<Integer> setB = new TreeSet<>();

		int n = sc.nextInt();
		for(int i = 0; i < n; i++) {
			setA.add(sc.nextInt());
		}

		int m = sc.nextInt();
		for(int i = 0; i < m; i++) {
			setB.add(sc.nextInt());
		}


		setA.retainAll(setB);

		for(int value : setA) {
			System.out.println(value);
