Leetcode 290. Word Pattern
Check whether the characters in pattern and the space-separated words in s have a bijective (one-to-one and onto) mapping that preserves order — i.e., each pattern letter maps to exactly one word and no two letters map to the same word, and substituting letters with their mapped words reproduces s.
