Set Intersection

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
