Web2. 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 ...

WebNov 26, 2024 · Your directed graph has 2 disconnected components. Component A is strongly connected. A is strongly connected because you can traverse to every other vertex in the component from every vertex in the component. From 4 we can get to 5 by following the edge (4,5). From 5 we can get to 4 by following the edge (5,4).

WebA connected graph may have a disconnected spanning forest, such as the forest with no edges, in which each vertex forms a single-vertex tree.
