It is a fairly common practice to traverse the vertices and edges of a graph. Consider a new implementation of graphs that keeps a Map of vertices as well as an unordered List of edges. This makes traversal of edges simple. What is the complexity of each of the other Graph operations?

16.15 It is a fairly common practice to traverse the vertices and edges of a
graph. Consider a new implementation of graphs that keeps a Map of vertices
as well as an unordered List of edges. This makes traversal of edges simple.
What is the complexity of each of the other Graph operations?
16.16 Extend the all-pairs minimum distance algorithm to keep track of the
shortest path between the nodes.
16.17 Explain why it is sometimes more efficient to compute the distance
from a single source to all other nodes, even though a particular query may be
answered with a partial solution.
