(a) Apply Dijkstra's Algorithm to the graph with A as the source/root and draw the graph for EACH
step of the algorithm (include the initial state!).
(b) Draw the minimum distance spanning tree associated with the algorithm with A as the root.
Label the vertices!
(c) Suppose a new graph is formed by deleting the edge between D and E. Run Dijkstra's Algorithm
on this new graph with A as the source/root. You only need to provide the final graph produced
by the algorithm.
(d) Explain how you know the graph from the previous question is disconnected using only the output
of Dijkstra's Algorithm.
