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.
We'll cover the following...
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
patternmust map to exactly one unique word ins.Each word in
smust map to exactly one unique character inpattern.No two characters map to the same word, and no two words map to the same character.
