Leetcode #3: Longest Substring With Repeating Characters

Master the Sliding Window technique with LeetCode #3! 🚀 Question link :- https://leetcode.com/problems/longest... The "Longest Substring Without Repeating Characters" problem is a classic software engineering interview question. In this video, we move beyond the brute-force approach to implement a highly optimized solution in Java. 🔍 What We’ll Solve: Given a string s, find the length of the longest substring without repeating characters. 🛠️ Key Concepts Covered: Brute Force: Why checking every substring is O(n^3) and how it fails. The Sliding Window (Basic): Using a HashSet to manage a moving window of unique characters (O(n)). Optimized Sliding Window: Using a HashMap to store character indices and "jump" the left pointer for maximum efficiency. Complexity Analysis: Why time is O(n) and space is O(min(n, m)).
