Sliding window maximum

CodingAlgorithms & data structuresSenior–Staff~30 min

Given an integer array nums and a window size k, return a list of the maximum value in each contiguous window of size k as the window slides from left to right. The array has 1 to 10^5 elements, values fit in 32-bit signed range, and 1 <= k <= len(nums). You should aim for O(n) overall.

Implement
max_sliding_window(nums: list[int], k: int) → list[int]
Examples
in[[1,3,-1,-3,5,3,6,7],3]out[3,3,5,5,6,7]
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.
