Solution: Word Pattern
Explore how to determine if a string follows a given pattern by applying a bijection constraint between characters and words. This lesson guides you through implementing a hash map approach that verifies consistent one-to-one mappings, helping you master a common coding interview pattern with efficient time and space complexity.

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.
