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

int main() {
  ios::sync_with_stdio(false);

  int n, m;
  cin >> n;
  vector<int> v1(n);

  int tmp;
  for (int i = 0; i < n; i++) {
    cin >> tmp;
    v1[i] = tmp;
  }

  cin >> m;
  vector<int> v2(m);
  for (int i = 0; i < m; i++) {
    cin >> tmp;
    v2[i] = tmp;
  }

  vector<int> r;
  set_intersection(v1.begin(), v1.end(), v2.begin(), v2.end(), inserter(r, r.end()));

  for (int i = 0; i < r.size(); i++) {
    cout << r[i] << endl;
  }
