Longest subarray within limit

CodingAlgorithms & data structuresSenior–Staff~30 min

Given an integer array nums and an integer limit, return the length of the longest contiguous subarray such that the absolute difference between its maximum and minimum element is at most limit. Array length up to 1e5.

Implement
longest_subarray_abs_diff(nums: list[int], limit: int) → int

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.
