Longest Substring Without Repeating Characters Leetcode #3 ) | JS | Sliding Window | Apple |Amazon

🔍 Problem: We're tackling the "Longest Substring Without Repeating Characters" problem using JavaScript and discussing both brute force and optimal sliding window approaches. 🧠 Approach: Starting with a brute force method, we analyse its O(n^2) time complexity before introducing the efficient two-pointer approach with O(n) time complexity. 💻 Coding Session: Follow along in this coding session as we implement both approaches step by step. Witness how sliding technique solves this optimally. 📎 Problem Link: https://leetcode.com/problems/longest-substring-without-repeating-characters/description/ 🔗 Solution Link: https://github.com/mohanmanis/Lectures/blob/main/src/blind75/longestSubstringWithoutRepeatingCharacters.js 🚀 Key Learnings: By understanding these approaches, you'll not only solve this problem but also gain insights into optimizing solutions for similar challenges. 🔔 Don't forget to subscribe to my channel for more Blind 75 series tutorials!
