One edit distance

CodingAlgorithms & data structuresMid–Senior~20 min

Given two strings s and t, return True if and only if they are EXACTLY one edit distance apart. One edit means inserting, deleting, or replacing a single character. Strings equal to each other (zero edits) are NOT one edit apart. 0 <= len(s), len(t) <= 10^4.

one_edit_distance(s: str, t: str) → bool

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.
