Find Longest Self-Contained Substring

Explore how to identify the longest self-contained substring within a string by using hash maps. Understand the problem constraints, logic, and strategies to efficiently solve substring uniqueness challenges in coding interviews. Implement and test your solution in a hands-on coding environment.

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:

  • t is not equal to the entire string s.

  • Every character in t does not appear anywhere else in s ...
