Number of Provinces | Number of Connected Components | DFS & BFS | Python, Java & C++

In this video, we solve the Number of Provinces problem using DFS and BFS and understand it in a simple and easy way. The key idea is to identify how many connected components are present in the graph. Every connected component represents one province. What you'll learn: What is the Number of Provinces problem? How provinces are represented using an adjacency matrix Understanding connected components Solving the problem using DFS Solving the problem using BFS How the visited array works Step-by-step example Python, Java & C++ implementations DFS vs BFS approach Time and space complexity Complexity Time: O(N²) Space: O(N) This is a very important problem for understanding Graph Traversal, Connected Components, DFS, and BFS and is commonly asked in coding interviews.
