Problem Statement

You are given a sequence of $N$ integers: $A=(A _ 1,A _ 2,\ldots,A _ N)$.

Print all even numbers in $A$ without changing the order.

Constraints

• $1\leq N\leq 100$
• $1\leq A _ i\leq 100\ (1\leq i\leq N)$
• $A$ contains at least one even number.
• All values in the input are integers.

Input

The input is given from Standard Input in the following format:

$N$

$A _ 1$ $A _ 2$ $\ldots$ $A _ N$

Output

Print a line containing the sequence of all even numbers in $A$, with spaces in between.

5
1 2 3 5 6

2 6

We have $A=(1,2,3,5,6)$. Among them are two even numbers, $A _ 2=2$ and $A _ 5=6$, so print $2$ and $6$ in this order, with a space in between.

5
2 2 2 3 3

2 2 2

$A$ may contain equal elements.
