Reorder List

Given a list L: L0 → L1 → … → Ln-1 → Ln, reorder it to: L0 → Ln → L1 → Ln-1 → L2 → Ln-2 → …

Output the reordered list as space-separated values.

Input:

1,2,3,4

Output:

1 4 2 3

Reasoning:

The input list is split into two parts: the first half and the second half in reverse order.
The first half of the list is 1, 2 and the second half in reverse order is 4, 3.
The two halves are then merged in an alternating manner: 1 from the first half, 4 from the second half, 2 from the first half, and 3 from the second half.
The final output is the merged list as space-separated values: 1 4 2 3.
