DSA with Python – What Are Connected Components in Graphs? – Part 119 [Hindi]

🚀 Welcome to Part 119 of Code & Debug’s DSA Python Course 2025!

In this lecture, we discuss the concept of Connected Components in graphs — one of the most misunderstood foundational concepts in Graph Theory. Many people confuse visually separated clusters as multiple graphs, but they are simply multiple components within a single graph.

📚 What you’ll learn in this video:
✅ What are connected components in a graph
✅ Difference between connected graph and disconnected graph
✅ Intuition behind undirected components vs directed strongly connected components
✅ Common misconceptions with visual separation

💡 Why is this important?
Understanding connected components is crucial before learning DFS, BFS, Topological Sort, Kosaraju’s algorithm, and Union-Find (DSU). It forms the core of many interview questions like “count the number of islands,” “friend circles,” and “provinces in a network.”
