House robber circular

CodingAlgorithms & data structuresMid–Senior~25 min

Houses with non-negative values are arranged in a circle given by 'nums' (the first and last houses are adjacent). Choose a subset of houses with maximum total value such that no two adjacent houses are chosen. Return the maximum total value. 1 <= len(nums) <= 10^5, 0 <= nums[i] <= 10^4.

Implement
rob_circular(nums: list[int]) → int
Examples

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.
