Connected Components in an Undirected Graph

WebA graph is a data structure that stores connected data. In other words, a graph G (or g) is defined as a set of vertices (V) and edges (E) that connects vertices. The examples of graph are a social media network, computer network, Google Maps, etc. Each graph consists of edges and vertices (also called nodes). Each vertex and edge have a relation. Web0. We can find the number of edges from the following observations: The degree of a vertex v counts the number of times v appears as the endpoint of an edge. If we sum … rothinaor
