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.

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.

Constraints

  • $1 \leq n \leq 2\times 10^5$
  • $0 \leq a_i \leq 10^9$
  • n and a_i are integers.

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.
