Sort 0’s, 1’s & 2’s in Telugu 🔥 | Brute, Better & Optimal Approaches Explained | DSA Series 💻

Welcome to another powerful episode of our DSA Series in Telugu! 💻🔥
In this video, we’ll learn how to Sort 0’s, 1’s, and 2’s — also known as the Dutch National Flag Problem, a very popular array interview question.

We’ll go through all three approaches —
👉 Brute Force
👉 Better (Counting Method)
👉 Optimal (Three Pointer Approach)

This problem teaches how to move from simple logic to highly efficient in-place sorting using constant space and O(n) time.

📘 What You’ll Learn in This Video:
Understanding the “Sort 0’s, 1’s, and 2’s” problem
Brute Force Approach using sorting
Better Approach using counting
Optimal Approach (Dutch National Flag Algorithm)
Step-by-step dry run and visualization
Time & Space Complexity comparison
Common interview pitfalls and variations

👩‍💻 Perfect for:
Students learning Data Structures & Algorithms in Telugu,
beginners preparing for coding interviews, and those wanting to strengthen array + pointer logic.

💡 By the End of This Video:
You’ll fully understand how to sort arrays efficiently, how to think in stages (brute → better → optimal), and how to implement the Dutch National Flag Algorithm confidently.
