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.

Sample Input 1

5
1 2 3 5 6

Sample Output 1

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.

Sample Input 2

5
2 2 2 3 3

Sample Output 2

2 2 2

$A$ may contain equal elements.

Sample Input 3

10
22 3 17 8 30 15 12 14 11 17

Sample Output 3

22 8 30 12 14
