Data Structures and Algorithms with Python | Free DSA with Python Course - DSA Python 2025 - Course Schedule I & II | Kahn’s Algo | Leetcode 207 & 210 - Part 138 [Hindi]

Welcome to Part 138 of Code & Debug’s DSA Python Course 2025! In this special video, we tackle two classic graph problems from Leetcode: 👉 Leetcode 207 - Course Schedule (Cycle Detection) 👉 Leetcode 210 - Course Schedule II (Topological Sort) Using Kahn’s Algorithm, we detect whether all courses can be completed (Cycle Detection) and return the order of course completion (Topological Sort) if possible. 📚 What you'll learn in this session: ✅ How to detect cycles in a directed graph ✅ Using Kahn’s Algorithm to solve Course Schedule problems ✅ Topological Sorting using BFS ✅ Real-world analogy of course prerequisites ✅ Step-by-step Python code explanation ✅ Time & Space Complexity Analysis 💡 These problems are frequently asked in interviews and are great for understanding graphs, indegrees, and dependency resolution. 🔗 Leetcode 207 - Course Schedule: https://leetcode.com/problems/course-schedule/ 🔗 Leetcode 210 - Course Schedule II: https://leetcode.com/problems/course-schedule-ii/ 👉 Refer to the article for better understanding: 🔗 https://codeanddebug.in/blog/course-schedule-1/ 📄 Full Playlist Sheet (All Questions in Order): https://docs.google.com/spreadsheets/d/1AWE15Fy3wD2iqu2vjK_R7cCiuvSsjYQclcdZmHpF66o/edit?usp=sharing 🎓 Enroll in the FREE Python DSA Course: https://codeanddebug.in/course/master-dsa-with-leetcode ⚡ Join the Self-Paced Zero to Hero DSA Course: https://codeanddebug.in/course/zero-to-hero-python-dsa 🙏 Like, Share & Subscribe to support Code & Debug and stay notified with the 🔔 bell icon! #CourseSchedule #Leetcode207 #Leetcode210 #TopologicalSort #CycleDetection #KahnsAlgorithm #PythonDSA #DSA2025 #CodeAndDebug #Part138 #GraphProblems #TechInterviews
