3 Sum Problem in Telugu 💡 | Better Approach Using Hashing Explained Step-by-Step | DSA Series 💻🔥

Welcome to another episode of our DSA Series in Telugu! 💻🔥 In this video, we’ll solve the 3 Sum Problem using a Better Approach with Hashing — a smart way to optimize the brute force method from O(n³) → O(n²) efficiently. You’ll understand how HashSet or HashMap can be used to find the triplets that sum to zero, avoid duplicates, and prepare for even more optimized solutions like the Two Pointer Approach. 📘 What You’ll Learn in This Video: Recap: Brute Force 3 Sum Logic (O(n³)) How Hashing reduces time complexity Using HashSet to track complements Handling duplicates in triplets Step-by-step dry run and visualization Code Implementation in C++, Python, and Java Comparison between Hashing and Two Pointer methods 👩‍💻 Perfect for: Beginners learning Data Structures & Algorithms in Telugu, students preparing for coding interviews, and anyone exploring Hashing + Array based problem-solving. 💡 By the End of This Video: You’ll learn how Hashing helps optimize 3 Sum, understand its advantages and limitations, and be ready to move into the Two Pointer Optimal Approach next. ✨ Languages Used: C++, Python, Java 🎓 Series: Telugu DSA Series (3 Sum Problem – Better Approach with Hashing) #arrays #dsaintelugu #dsa #algorithms #datastructures #programmingintelugu #codingforbeginners #interviewpreparation #dsa2025 #dsaforbeginners 3 sum problem in telugu 3 sum better approach using hashing in telugu 3 sum with hashing telugu hashing approach for 3 sum in telugu 3 sum explained in telugu dsa hashing problems in telugu hashmap and hashset in telugu array problems in telugu 3 sum dry run explained in telugu hashing for beginners telugu dsa array problems in telugu data structures and algorithms in telugu dsa for beginners in telugu learn arrays step by step in telugu coding for beginners in telugu learn programming in telugu telugu dsa series telugu coding tutorial dsa 2025 in telugu hashing in telugu
