Link to the question: https://leetcode.com/problems/3sum/ Link to my GitHub: https://github.com/JyotinderSingh Link to my Website: https://jyotindersingh.com/ Notes: 1. Why don't we use a hashmap as in the original Two Sum problem? A. This is because we can find a better approach, once we've sorted the array - that allows us to solve the problem with the same (and in some cases better) time complexity, while using CONSTANT SPACE. 2. Why do we run the while loops to skip similar elements? A. We don't want duplicates in the problem set Timestamps: 00:00 - Problem Introduction 01:14 - Algorithm Approach 03:07 - Coding Walkthrough _______________________________________ Some great channels to learn more: Tushar Roy:    / tusharroy2525   Errichto:    / @errichto   Nick White:    / @nickwhite   Kevin Naughton Jr:    / @kevinnaughtonjr
