Data Structures and Algorithms with Python | Free DSA with Python Course - DSA in Python - Combination Sum | Recursion & Backtracking | Leetcode 39 - Part 75 [Hindi]

🚀 Welcome to Part 75 of Code & Debug’s DSA in Python Course! In this lecture, we solve Leetcode 39: Combination Sum, a fundamental Recursion & Backtracking problem that helps in understanding combinatorial sum generation and subset problems. 📚 What you’ll learn in this video: ✅ Understanding the problem statement & constraints ✅ Recursive Backtracking approach to generate valid combinations ✅ Avoiding duplicate combinations using pruning techniques ✅ Time complexity analysis and best practices ✅ Handling edge cases efficiently 💡 Why is this important? This problem is widely asked in FAANG interviews and strengthens your grasp of Recursion, Backtracking, and Dynamic Programming. Mastering it will help in solving problems like Subset Sum, Partition Equal Subset Sum, and Coin Change Problems. 👉 Link to solve this question: https://leetcode.com/problems/combination-sum/description/ 👉 Refer the article below for better understanding: https://codeanddebug.in/blog/combination-sum/ 👉 📄 Access the full YouTube DSA Playlist Sheet (All Questions in Order): 🔗 https://docs.google.com/spreadsheets/d/1AWE15Fy3wD2iqu2vjK_R7cCiuvSsjYQclcdZmHpF66o/edit?usp=sharing 👉 Enroll in the free DSA Python course here: https://codeanddebug.in/course/master-dsa-with-leetcode 👉 Enroll for Self-Paced Advance DSA course here: https://codeanddebug.in/course/zero-to-hero-python-dsa 🙏 Thank you for supporting Code & Debug!
