Coin Change Problem Telugu | Greedy, BFS Approach | Leetcode 322 | Python DSA | srkcodes
2Welcome back to srkcodes! In this Day 116 Telugu coding tutorial, we solve Leetcode 322: Coin Change, one of the most important DSA interview questions for dynamic programming and problem-solving techniques.
🔍 What’s Covered in This Video:
1️ ⃣ Problem Understanding: Infinite coins, minimum coins needed
2️ ⃣ Greedy Approach: Where it works and where it fails
3️ ⃣ BFS Approach: Optimized search for fewest coins
4️ ⃣ Time and space complexities for each method
This problem is a favorite in coding interviews, tech career prep, and dynamic programming tutorials, and mastering it strengthens your Python programming for interviews.
💡 Key Takeaways:
Learn why greedy algorithms don't always work for coin change
Master BFS for minimum step problems in DSA
Deepen your understanding of time complexity vs optimal solutions
Strengthen your Python dynamic programming skills
Get real-world ready for software development interviews
Whether you are a beginner aiming for your first tech job or prepping for tough coding rounds, this DSA tutorial in Telugu will help you level up quickly!
