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.

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.

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.

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
