Data Structures and Algorithms with Python | Free DSA with Python Course - DSA in Python - Bellman-Ford Algorithm | Detect Negative Cycles | GFG Problem | Part 153 [Hindi]

📘 Welcome to Part 153 of Code & Debug’s DSA Python Course! In this video, we explore the Bellman-Ford Algorithm, a fundamental graph algorithm for finding the shortest path from a single source even when negative edge weights are present. We solve the GFG problem "Distance from the Source (Bellman-Ford Algorithm)", and walk through detecting negative weight cycles — a concept that’s frequently tested in interviews. 👨‍🏫 What’s covered in this video: ✅ When to use Bellman-Ford over Dijkstra ✅ Relaxation of edges in V-1 passes ✅ Detecting negative weight cycles ✅ Python implementation from scratch ✅ Edge list vs adjacency list differences ✅ Time & Space Complexity analysis This algorithm is crucial when dealing with graphs containing negative edges, and knowing how to detect infinite loop scenarios is a must. 🔗 GFG Problem - Distance from the Source (Bellman-Ford): https://www.geeksforgeeks.org/problems/distance-from-the-source-bellman-ford-algorithm/1 👉 Refer to the article for better understanding: 🔗 https://codeanddebug.in/blog/bellman-ford-algorithm/ 📄 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 🚀 Upgrade to the Full DSA Mastery Track: https://codeanddebug.in/course/zero-to-hero-python-dsa Keep learning and building with Code & Debug.
