LeetCode 15 | 3Sum

In this problem, we solve LeetCode 15 – 3Sum, one of the most popular interview questions that combines sorting with the Two Pointer technique to efficiently find unique triplets. We explore how a naive brute-force solution can be optimized by leveraging sorted arrays and smart pointer movements to eliminate duplicate combinations. 💡 In this video: -Understanding the Problem Statement -Brute Force Approach -Why Sorting Helps -Two Pointer Technique -Handling Duplicate Triplets -Optimizing Search Space -Step-by-Step Dry Run -Time & Space Complexity Analysis -Java Implementation 🎯 This problem is a cornerstone of array-based interview preparation and helps build intuition for advanced Two Pointer and k-Sum problems. 📌 Follow & Connect with Us: 🌐 Website: leetverse.vercel.app 📝 Registration link : https://forms.gle/QkGwatVBXDr6dpxi6 📸 Instagram:   / leetverse   ✨ LeetVerse — Learn, Code, Grow! #LeetCode #DSA #3Sum #TwoPointers #Arrays #Java #CodingInterview #ProblemSolving #LeetVerse #Algorithms
