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.
