Given a directed graph G with positive-weight edges, a starting vertex s, and an ending vertex t, there may be more than one possible shortest path from s to t. The best shortest path is the path with the fewest edges. (a) Describe and analyze an algorithm to find the best shortest path from s to t. (b) Implement your algorithm (in whatever programming language you like) and submit the program, Given a directed graph G with positive-weight edges, a starting vertex s, and an ending vertex t, there may be more than one possible shortest path from s to t.
