Step 1
The distance from vertex 2 to itself is 0, and all other distances are infinity. - Distance: [0, ∞, ∞, ∞, ∞, ∞] - Previous vertex: [None, None, None, None, None, None] Show more…

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.
