Smallest suffix

CodingAlgorithms & data structuresSenior–Staff~38 min

Given a string s, return its lexicographically smallest suffix (the suffix that would sort first among all suffixes of s). 1 <= len(s) <= 50000, lowercase letters. Example: for 'banana' the suffixes sorted are a < ana < anana < banana < na < nana, so the answer is 'a'.

Implement
smallest_suffix(s: str) → str
Examples
in["banana"]out"a"
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.
