Python Program To Check Graph Is Strogly Connected or Weakly connected Using BFS | Graph

This video explains how to use the BFS (Breadth-First Search) algorithm to determine whether a given directed graph is strongly connected or weakly connected. A strongly connected graph is one where every vertex is reachable from every other vertex, while a weakly connected graph is one where, if treated as an undirected graph, it becomes connected.

The tutorial walks through a Python program that first checks if the graph is connected using BFS. If all nodes are visited, the graph is assumed to be connected. However, the program also handles cases where the graph is weakly connected by reversing the graph's edges and performing BFS again. Based on the traversal results, the program determines if the graph is strongly connected or weakly connected. The video provides a detailed explanation and shows the implementation of the solution with sample graphs.
