Minimum length subarray with sum

CodingAlgorithms & data structuresMid–Senior~20 min

Given an array a of positive integers and a positive integer target, return the minimal length of a contiguous subarray whose sum is >= target. If no such subarray exists, return 0.

Implement
min_len_subarray_sum(a: list[int], target: int) → int
Examples
in[[2,3,1,2,4,3],7]out2
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.
