1. Do a depth-first search of this graph starting with node S. When you have the choice of two or more edges to unexplored nodes to traverse, take the shortest edge first. List the discovery and finishing times of each node in the table below. If your depth first search from S ends without exploring all nodes of the graph (it will), continue the search from the unexplored node with the earliest letter of the alphabet.
