Solution: Word Pattern

Understand the approach to solve the word pattern problem by implementing hash maps to verify bijection between characters and words. This lesson helps you practice mapping consistency checks and gain insights into optimizing pattern matching with linear time complexity using Go.

Statement

You are given a pattern and a string, s. You need to determine whether the string s follows the same pattern.

A string s is said to follow a pattern if a bijection exists between a character in the pattern and a non-empty word in s.

  • Each character in the pattern must map to exactly one unique word in s.

  • Each word in s must map to exactly one unique character in pattern.

  • No two characters map to the same word, and no two words map to the same character.

Constraints:

  • 11 \leq pattern.length 100\leq 100 ...
