For the first part assume that G has s components. Then as it's forest we have that each such component is a tree and hence if V 1 is the number of vertices in the first component then there are V 1 − 1 edges in it. Obviously the number of edges in G is given by: E = ∑ n = 1 s ( V n − 1) = ∑ n = 1 s V n − s = V − s s ... dwight\\u0027s desk in wrapping paper

WebMay 18, 2016 · In graph theory, 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. This means the subgraph we are talking about does have to meet following criterion: A connected component is a maximal connected subgraph of an undirected graph. Each vertex belongs to exactly one connected component, as does each edge. A graph is connected if and only if it has exactly one connected component. The strong components are the maximal strongly connected subgraphs of a directed graph. A vertex cut or separating set of a connected graph G is a set of vertices whose removal render…
