Maximum subarray sum

CodingAlgorithms & data structuresEntry–Mid~15 min

Given an integer array, return the largest sum of any contiguous subarray (at least one element).

Implement
max_subarray(nums: list[int]) → int
Examples
in[[-2,1,-3,4,-1,2,1,-5,4]]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.
