Longest ones after flipping zeros

CodingAlgorithms & data structuresMid–Senior~20 min

Given a binary array nums and an integer k, you may flip at most k of the 0s to 1s. Return the length of the longest contiguous subarray that contains only 1s after performing at most k flips. Here 1 <= len(nums) <= 10^5 and 0 <= k <= len(nums).

Implement
longest_ones(nums: list[int], k: int) → int
Examples
in[[1,1,1,0,0,0,1,1,1,1,0],2]out6
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.
