Consider the following weighted graph: Use Dijkstra's algorithm to find a shortest path from vertex a to vertex z. You don't need to show every step of the algorithm, but to receive full credit you should • draw the final graph with all the vertices labeled, • indicate how many times the main while loop is executed, and • indicate which edges give a shortest path from a to z.

Use Dijkstra's algorithm for finding the shortest paths from vertex a to all other vertices of the graph in the figure. Indicate how the weights of the vertices are updated in the course of the algorithm execution. Find a shortest path from vertex a to vertex f, mark it on the figure and calculate its length.
Use Dijkstra's algorithm to determine the length of a shortest path between the vertices a and h in the following weighted graph. It is very important to note that that every iteration of the algorithm must be shown and a brief explanation for every step (subgraph) must be provided, as just writing the correct length of the shortest path is not enough at all. In other words, you must show your work.
