Solution: Find Longest Self-Contained Substring
Explore how to identify the longest self-contained substring in a string by using hash maps to track character occurrences. Learn to implement a linear time algorithm that expands and validates substring windows, while managing character boundaries for uniqueness. This lesson enhances your ability to solve substring problems using hash map patterns efficiently.

Statement
You are given a string, s, consisting of lowercase English letters. Your task is to find the length of the longest self-contained substring of s.
A substring t of s is called self-contained if:
tis not equal to the entire strings.Every character in
