Question
Given an integer array nums and two valid 0-based indices left and right with left <= right, reverse the elements from left to right inclusive, leaving everything outside that range untouched, and return the array. Do the reversal in place by swapping from both ends of the range — no slicing out a sub-array and rebuilding. Example: nums = [1, 2, 3, 4, 5], left = 1, right = 3 gives [1, 4, 3, 2, 5].
reverse_segment(nums: list[int], left: int, right: int) → list[int][[1,2,3,4,5],1,3]out[1,4,3,2,5]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.
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.
