Question
Given a singly linked list encoded as a plain list of its values L0, L1, ..., Ln-1, reorder it to L0, Ln-1, L1, Ln-2, L2, Ln-3, ... and return the reordered values as a plain list. Do not just reverse it; interleave from both ends. The list may be empty.
Implement
reorder_list(vals: list[int]) → list[int]Examples

[[1,2,3,4]]out[1,4,2,3]What a strong answer looks like
State your approach and its time/space complexity out loud before you optimize. Handle the edge cases (empty input, duplicates, overflow), and say why you chose this over the brute force. Green tests are the floor, not the grade.
Learn the concepts
Vibe coding: describe the solution in plain language (or narrate it) and the coach grades your approach. Generating runnable code from your description is coming next.
Run or narrate your approach, then ask the coach.
