Number of Connected Components in an Undirected Graph. Given an undirected graph, it’s important to find out the number of connected components to analyze the structure of the graph – it has many real-life applications. Given an undirected graph g, the task is to print the number of connected components in the graph. Each node in the graph contains a label and a list of its neighbors. We can use either DFS or BFS for this task. Each element of edges is a pair [u, v] with u < v, that represents an undirected edge connecting nodes u and v. Return an edge that can be removed so that the resulting graph is a tree of N nodes. An undirected graph is sometimes called an undirected network. Find the number connected component in the undirected graph. We simple need to do either BFS or DFS starting from every unvisited vertex, and we get all strongly connected components.
