Data Structures and Algorithms with Python | Free DSA with Python Course - DSA Python - Detect Cycle in Directed Graph using Kahn’s Algorithm | GFG Problem - Part 137 [Hindi]

Cycle Detection in Directed Graph using Kahn’s Algorithm | Part 137 of Code & Debug's DSA Python 2025 Series! In this video, we explore a non-recursive, indegree-based approach to detect cycles in a Directed Acyclic Graph (DAG) using Kahn's Algorithm (BFS). 📌 Topics Covered: ✔️ What is cycle detection in directed graphs? ✔️ How Kahn's algorithm helps in identifying cycles ✔️ Understanding indegree and queue processing ✔️ Complete code walkthrough using Python ✔️ Time & Space Complexity Analysis 💻 If the number of nodes in the final topological order is less than V, that means there's a cycle in the graph. 👉 Practice 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-kahns-algorithm-bfs/ 📄 Full DSA YouTube Playlist (All questions in order): 🔗 https://docs.google.com/spreadsheets/d/1AWE15Fy3wD2iqu2vjK_R7cCiuvSsjYQclcdZmHpF66o/edit?usp=sharing 🚀 Free Master DSA with Python Course: 🔗 https://codeanddebug.in/course/master-dsa-with-leetcode 💡 Self-Paced Advanced DSA Course (Zero to Hero): 🔗 https://codeanddebug.in/course/zero-to-hero-python-dsa 🎯 Don't forget to like, comment, and subscribe for more high-quality content from Code & Debug.
