🎯 Two Sum Problem: 4 Approaches Explained & Coded! 🎯

Hi Everyone, welcome to “Bit By Bit”! 🎯 This is a deep dive into a foundational problem in our Arrays & Hashing Concepts & Questions playlist! 🎯 Two Sum Problem: 4 Approaches Explained & Coded! 🎯 Hey everyone! 👋 Welcome back to Bit By Bit! In today's video, we're tackling the famous Two Sum problem, a must-know for any aspiring developer, and we're exploring four distinct approaches to solve it! 🚀 We'll explore: ✅ Approach 1: Brute Force - A straightforward, intuitive way to start. ✅ Approach 2: Sorting + Binary Search - How combining these techniques can improve efficiency. ✅ Approach 3: Sorting + Two Pointers - A highly optimized method for sorted arrays. ✅ Approach 4: Using a Hash Set (Optimal) - The most efficient and commonly used solution for its speed. ✅ A detailed explanation and dry run 🚶‍♂️🚶‍♀️ for each of these four approaches to solidify your understanding. ✅ Complete and well-commented code implementations 💻 on GeeksforGeeks (GFG) for all four methods. Understanding these different ways to solve Two Sum will not only help you ace interviews but also build a strong foundation in algorithm design and optimization! ➡️Github solution link (Java + C++) : https://github.com/Ayush2649/Intervie...) ➡️ Explore our Arrays & Hashing Concepts & Questions playlist for more essential problems: [   • Arrays & Strings Popular Interview Questions  ] 📚 ➡️ Catch our previous video on [   • 🥈 Finding the Second Largest Element in an...  ] ⏪ ➡️ Subscribe to Bit By Bit for more engaging DSA explanations:    / @bitbybit1430   ❤️ ➡️ Practice all approaches on GeeksForGeeks: [https://www.geeksforgeeks.org/problem...] Timestamps: [0:00] Introduction to the Two Sum Problem 🎬 [1:13] Approach 1: Brute Force Explained & Dry Run 🤔 [3:50] Approach 2: Sorting + Binary Search Explained & Dry Run 🕵️‍♂️ [6:20] Approach 3: Sorting + Two Pointers Explained & Dry Run ✌️ [9:30] Approach 4: Using a Hash Set (Optimal) Explained & Dry Run. ✨ [12:37] Code for Brute Force on GFG 👨‍💻 [13:57] Code for Sorting + Binary Search on GFG 💻 [17:05] Code for Sorting + Two Pointers on GFG 🚀 [19:55] Code for Hash Set Approach on GFG 💡 [21:05] Conclusion & Which Approach to Use When 🎉 ╔═╦╗╔╦╗╔═╦═╦╦╦╦╗╔═╗ ║╚╣║║║╚╣╚╣╔╣╔╣║╚╣═╣ ╠╗║╚╝║║╠╗║╚╣║║║║║═╣ ╚═╩══╩═╩═╩═╩╝╚╩═╩═╝ Don't forget to LIKE 👍, COMMENT 💬, and SHARE 📤 this video if you found it helpful!
