💡 In this video, we dive deep into the Two Pointer Technique in Data Structures and Algorithms (DSA) and solve the Two Sum Problem using the brute force approach. This is perfect for beginners and anyone preparing for coding interviews or competitive programming.

💡 We also discuss patterns that help in cracking DSA rounds, placement tests, and FAANG-level interviews. By watching this, you'll learn how to approach array problems, find duplicates, and tackle pair sum or pair difference problems effectively.

✅ What You’ll Learn in This Video:
➜ What is the Two Pointer Technique and how to apply it.
➜ Step-by-step brute force solution for Two Sum problem.
➜ How to analyze array problems efficiently.
➜ Understanding coding patterns to crack interviews faster.

📌 Who Should Watch:
➜ Beginners in DSA
➜ Students preparing for coding interviews
➜ Anyone aiming for placement tests or FAANG interviews
