from the source vertex a to all other vertices. Fill out the table shown below. Set S contains
vertices in the order of vertices removed from the min priority queue Q. Finally, reconstruct the
path from vertex a to vertex e and give the total cost of the path. Consider alphabetic order for
EXTRACT-MIN (Q) with same weight.
