Word Pattern

Explore how to identify if a string follows a specific pattern by establishing a unique mapping between pattern characters and words in the string. This lesson guides you through implementing this logic using hash maps in C#, helping you understand key concepts for coding interviews. You'll learn to handle constraints and practice your solution in a hands-on coding environment.

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.
