Rearrange string no adjacent duplicates

CodingAlgorithms & data structuresMid–Senior~25 min

Given a string s of lowercase letters (1 <= len(s) <= 500), rearrange its characters so that no two ADJACENT characters are the same and return any such arrangement. If it is impossible, return the empty string. For these tests the reference uses a deterministic max-heap tie-broken by lowest character.

Implement
reorganize_string(s: str) → str
Examples
in["aab"]out"aba"
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.
