Replace words with shortest root
Given a list of root words `roots` and a `sentence` of space-separated lowercase words, replace every word in the sentence with the SHORTEST root in `roots` that is a prefix of it; if no root is a prefix, keep the word unchanged. Return the resulting sentence as a single space-separated string. Words and roots are lowercase. `0 <= len(roots) <= 1000`.

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.
