Consider the weight matrix D and the predecessor matrix II output by the Floyd-Warshall algorithm. What is the most efficient way, and required runtime to use this to: a.Detect a negative-weight cycle. b.Determine the diameter (The length of the "longest shortest path") of the graph. c.Find a central vertex of the graph. That is, the set of all vertices A where the greatest distance d(a, b) to other vertices B is minimal. d.Determine the connected components of the graph.
