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

  set<int> U;
  int n;
  cin >> n;
  set<int> A;
  for (int i = 0; i < n; i++){
    int a;
    cin >> a;
    A.insert(a);
  }
  int m;
  cin >> m;
  for (int i = 0; i < m; i++){
    int b;
    cin >> b;
    if (A.count(b)){
      U.insert(b);
    }
  }
  for (auto itr = U.begin(); itr != U.end(); itr++){
    cout << *itr << endl;
