Isomorphic strings

CodingAlgorithms & data structuresEntry–Mid~15 min

Two strings are isomorphic if characters in the first can be consistently replaced to get the second (one-to-one mapping). Return whether they are.

Implement
is_isomorphic(s: str, t: str) → bool
Examples
in["egg","add"]outtrue
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.
