is the graph directed or indirect? b) is the graph weighted or unweighted? c) is the graph connected, strongly connected, or unconnected?if it is not connected, give an example of why not. d) is the graph cyclic or acyclic?if it is cyclic, give an example of a cycle. e) what is the degree of each vertex?if it is directed, what is the in-degree and out-degree of each vertex? f) write a complete adjacency list and adjacency matrix representation of the graph.
