Data Structures and Algorithms with Python | Free DSA with Python Course - DSA Python - Topological Sort Using DFS | GFG Problem | Directed Acyclic Graph - Part 135 [Hindi]

🚀 Welcome to Part 135 of Code & Debug’s DSA Python Course 2025! In this video, we dive deep into Topological Sorting of a Directed Acyclic Graph (DAG) using Depth First Search (DFS) — a core concept in graph theory and a frequent topic in technical interviews. 📚 What you’ll learn in this video: ✅ What is topological sort and where it is used ✅ DAGs and their real-world applications ✅ Step-by-step DFS implementation ✅ How to maintain a stack to reverse the ordering ✅ Time and space complexity analysis 💡 This problem is fundamental in understanding task scheduling, dependency resolution (like build systems), and cycle detection. 👉 Practice the problem on GFG: 🔗 https://www.geeksforgeeks.org/problems/topological-sort/1 👉 Refer to the article for better understanding: 🔗 https://codeanddebug.in/blog/topological-sort-in-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!
