Longest equal zero-one subarray

CodingAlgorithms & data structuresMid–Senior~20 min

Given a binary array nums containing only 0s and 1s, return the length of the longest contiguous subarray that contains an equal number of 0s and 1s. If no such subarray exists, return 0. Here 1 <= len(nums) <= 10^5.

Implement
find_max_length(nums: list[int]) → int
Examples
in[[0,1,0]]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.
