Find the Connected Component in the Undirected Graph 431 Question. Each node in the graph contains a label and a list of its neighbors. The Time complexity of the program is (V + E) same as the complexity of the BFS. (a connected component (or just component) of an undirected graph is a subgraph in which any two vertices are connected to each other by paths, and which is connected to no additional vertices in the supergraph.) An undirected graph is graph, i.e., a set of objects (called vertices or nodes) that are connected together, where all the edges are bidirectional. 2) Do following for every vertex 'v'. 1) Initialize all vertices as not visited. Given n nodes labeled from 0 to n - 1 and a list of undirected edges (each edge is a pair of nodes), write a function to find the number of connected components in an undirected graph. We can use either DFS or BFS for this task. Number of Connected Components in an Undirected Graph Given n nodes labeled from 0 to n - 1 and a list of undirected edges (each edge is a pair of nodes), write a function to find the number of connected components in an undirected graph. You can maintain the visited array to go through all the connected components of the graph.
