Скачать или смотреть 3 Sum Problem in Telugu 🔥 | Optimal Two Pointer Approach Explained Step-by-Step | DSA Series 💻

Welcome to another episode of our DSA Series in Telugu! 💻🔥
In this video, we’ll master the 3 Sum Problem using the Optimal Two Pointer Approach — reducing the time complexity from O(n³) (brute force) to O(n²) with clean, elegant logic.

You’ll understand how sorting + two moving pointers make this problem efficient and interview-ready.

📘 What You’ll Learn in This Video:
Quick recap of Brute Force & Hashing methods
Sorting and pointer movement intuition
Step-by-step Two Pointer logic to find triplets that sum to 0
Handling duplicates efficiently
Complete dry run & code walkthrough
Time & Space Complexity analysis
Interview tips and common mistakes

👩‍💻 Perfect for:
Students learning Data Structures & Algorithms in Telugu,
beginners preparing for coding interviews, and anyone who wants to build a solid foundation in Two Pointer optimization.

💡 By the End of This Video:
You’ll clearly know how to apply the Two Pointer Technique to solve 3 Sum efficiently and be ready for advanced problems like 4 Sum and 3 Sum Closest.
