Data Structures and Algorithms with Python | Free DSA with Python Course - DSA in Python Course - Alien Dictionary | Topological Sort in Graph | GFG | Part 141 [Hindi]

👽 Welcome to Part 141 of Code & Debug’s DSA in Python Course! In this session, we solve the popular Alien Dictionary problem from GFG using Topological Sorting in Directed Graphs. This is a classic application of Kahn’s Algorithm / DFS-based Topo Sort, where we infer the character order of an alien language based on a sorted dictionary. 🔍 In this video, you will learn: ✅ How to model problems as Directed Acyclic Graphs (DAG) ✅ Building adjacency list based on character precedence ✅ Performing Topological Sort (Kahn’s Algorithm / DFS approach) ✅ Dry run, edge cases & input modeling ✅ Complete time and space complexity analysis 📄 GFG Problem Link: https://www.geeksforgeeks.org/problems/alien-dictionary/1 👉 📄 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 💬 Don’t forget to Like 👍, Share 🔁, Comment 💬, and Subscribe 🔔 for more amazing content! #AlienDictionary #TopologicalSort #KahnsAlgorithm #GraphProblems #GFG #PythonDSA #CodeAndDebug #Part141 #GraphCharacterOrdering #InterviewPrep #DirectedGraph #TopoSort
