Solution: Word Pattern
Explore how to verify if a string's sequence of words matches a given character pattern using hash maps. Understand the one-to-one correspondence (bijection) between pattern characters and words, and learn to implement an efficient linear-time algorithm. This lesson equips you with the ability to handle pattern matching problems commonly asked in coding interviews.

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.
