Data Structures and Algorithms with Python | Free DSA with Python Course - DSA in Python - Shortest Path in Undirected Graph with Unit Distance | BFS | GFG | Part 142 [Hindi]

🚀 Welcome to Part 142 of Code & Debug’s DSA in Python Course! In this session, we solve the problem Shortest Path in an Undirected Graph with Unit Distance from GFG using the Breadth-First Search (BFS) algorithm. This is a classic single-source shortest path problem where edge weights are 1, making BFS the most efficient approach. 🔍 What you'll learn in this video: ✅ Why BFS works best for graphs with unit weights ✅ How to initialize distance array properly ✅ BFS traversal for minimum path discovery ✅ Handling disconnected nodes (distance = -1) ✅ Complete time & space complexity breakdown 📄 GFG Problem Link: https://www.geeksforgeeks.org/problems/shortest-path-in-undirected-graph-having-unit-distance/1 👉 Refer to the article for better understanding: 🔗 https://codeanddebug.in/blog/shortest-path-in-an-undirected-graph/ 📚 Python DSA Course Playlist with Sheet: https://docs.google.com/spreadsheets/d/1AWE15Fy3wD2iqu2vjK_R7cCiuvSsjYQclcdZmHpF66o/edit?usp=sharing 🧠 Zero to Hero DSA Course: https://codeanddebug.in/course/zero-to-hero-python-dsa 🧩 Leetcode-Based DSA Masterclass (Free): https://codeanddebug.in/course/master-dsa-with-leetcode 👍 Like, 🔁 Share, 💬 Comment your doubts, and 🔔 Subscribe for more such DSA breakdowns! #ShortestPath #BFS #GraphAlgorithms #UndirectedGraph #GFG #PythonDSA #CodeAndDebug #Part142 #SingleSourceShortestPath #UnitDistanceGraph
