Word pattern

CodingAlgorithms & data structuresEntry–Mid~15 min

Given a pattern and a space-separated string, return whether the string follows the pattern (a bijection between pattern letters and words).

Implement
word_pattern(pattern: str, s: str) → bool
Examples
in["abba","dog cat cat dog"]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.
