1. Using the given Java implementation of Dijkstra's algorithm (see video below for more detail), write a Java program that prints all shortest paths from vertex "A" to other vertices in the depicted graph above. Please note that since the given graph is undirected, every undirected edge between vertex u and v represents two directed edges: (1) edge from u to v and (2) edge from v to u.

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.
