Dijkstra's Algorithm: Perform Dijkstra's on the following graph a. You must start at a - since this is a single source shortest path algorithm b. You must show the state of the priority queue before each addition to the path c. Indicate on the graph the paths (circle edges part of a path)

You're running Dijkstra's algorithm to find all shortest paths starting with vertex A in the graph below, but you pause after vertex E has been added to the solution (and the relaxation step for vertex E has been performed). Annotate the graph as follows: (1) label each node with its current dist value, (2) darken the edges that are part of the current spanning tree (i.e., the parent links), (3) draw a dotted circle around the "cloud'' of vertices that...
