Problem Statement

You are given an integer sequence of length n, a_1, ..., a_n.
Let us consider performing the following n operations on an empty sequence b.

The i-th operation is as follows:

Append a_i to the end of b.

Reverse the order of the elements in b.

Find the sequence b obtained after these n operations.

Constraints

1 \leq n \leq 2\times 10^5

0 \leq a_i \leq 10^9

n and a_i are integers.

Input

Input is given from Standard Input in the following format:

n
a_1 a_2 ... a_n

Output

Print n integers in a line with spaces in between.
The i-th integer should be b_i.

Sample Input 1

4
1 2 3 4

Sample Output 1

4 2 1 3

After step 1 of the first operation, b becomes: 1.

After step 2 of the first operation, b becomes: 1.

After step 1 of the second operation, b becomes: 1, 2.

After step 2 of the second operation, b becomes: 2, 1.

After step 1 of the third operation, b becomes: 2, 1, 3.

After step 2 of the third operation, b becomes: 3, 1, 2.

After step 1 of the fourth operation, b becomes: 3, 1, 2, 4.

After step 2 of the fourth operation, b becomes: 4, 2, 1, 3.

Thus, the answer is 4 2 1 3.

Sample Input 2

3
1 2 3

Sample Output 2

3 1 2

As shown above in Sample Output 1, b becomes 3, 1, 2 after step 2 of the third operation. Thus, the answer is 3 1 2.

Sample Input 3

1
1000000000

Sample Output 3

1000000000

Sample Input 4

6
0 6 7 6 7 0

Sample Output 4

0 6 6 0 7 7

Solution in PHP (5.6.30) (judge verdict: Wrong Answer)

<?php

$count = trim(fgets(STDIN));

$rec_array = trim(fgets(STDIN));

$parts = explode(" ", $rec_array);

$array = array();

$string	 = '';
$i		 = 0;

if ($count % 2 == 0)
{

	for ($i = $count - 1; $i > 0; $i-=2)
	{
		$string .= $parts[$i]." ";
	}

	for ($i = 0; $i < $count; $i+=2)
	{
		$string .= $parts[$i]." ";
	}
}
else
{
	
		for ($i = $count; $i >= 0; $i-=2)
	{
		$string .= $parts[$i]." ";
	}
	

	
	for ($i = 0; $i < $count; $i+=2)
	{
		$string .= $parts[$i]." ";
	}
}


echo trim($string);
echo "\n";
