Reorder list to first-last pattern

CodingAlgorithms & data structuresMid–Senior~25 min

You are given a singly linked list as a Python list of integer values, in order from head to tail. Reorder it so that it follows the pattern L0, Ln, L1, Ln-1, L2, Ln-2, ... (first, last, second, second-last, ...). You must conceptually relink nodes rather than just swapping values, but for this exercise return the reordered sequence as a plain Python list. The list has 0 to 5*10^4 nodes.

Implement
reorder_list(values: list[int]) → list[int]
Examples
in[[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.
