Data Structures and Algorithms with Python | Free DSA with Python Course - DSA Python - Detect Cycle in Directed Graph | GFG Problem | DFS + Path Visited - Part 134 [Hindi]

🚀 Welcome to Part 134 of Code & Debug’s DSA Python Course 2025! In this lecture, we solve the classic "Detect Cycle in a Directed Graph" problem from GeeksforGeeks using DFS and path tracking. A must-know technique for identifying cycles in directed graphs. 📚 What you’ll learn in this video: ✅ Understanding the difference between directed and undirected cycle detection ✅ How to use visited[] and pathVisited[] arrays effectively ✅ Full DFS-based Python implementation ✅ Time & space complexity breakdown ✅ Real-world use cases of cycle detection 💡 This concept is critical for tackling topological sorting, deadlock detection, and dependency resolution problems in coding interviews. 👉 Practice the problem on GFG: 🔗 https://www.geeksforgeeks.org/problems/detect-cycle-in-a-directed-graph/1 👉 Refer to the article for better understanding: 🔗 https://codeanddebug.in/blog/detect-cycle-in-a-directed-graph/ 👉 📄 Access the full YouTube DSA Playlist Sheet (All Questions in Order): 🔗 https://docs.google.com/spreadsheets/d/1AWE15Fy3wD2iqu2vjK_R7cCiuvSsjYQclcdZmHpF66o/edit?usp=sharing 👉 Enroll in this FREE DSA Python course here: 🔗 https://codeanddebug.in/course/master-dsa-with-leetcode 👉 Enroll for Self-Paced Advanced DSA course here: 🔗 https://codeanddebug.in/course/zero-to-hero-python-dsa 🙏 Thank you for supporting Code & Debug!
