Word break sentences

CodingAlgorithms & data structuresSenior–Staff~30 min

Given a string s and a dictionary of words, return all the ways to add spaces so that s becomes a sentence of dictionary words. Each result is a space-joined sentence; return the list sorted lexicographically. Words may be reused. 1 <= len(s) <= 20.

Implement
word_break_all(s: str, wordDict: list[str]) → list[str]
Examples
in["catsanddog",["cat","cats","and","sand","dog"]]out["cat sand dog","cats and dog"]
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.
