Quiz 4, Thursday, 10/30
(20 minutes. Open notes)
Suppose that Darth Vader has tampered with
your implementation of the stack data structure.
When you perform a pop operation, you
don't get the top most element from the stack; instead you get the element
just below the top most element.
Of course, if the stack has only one element, then that is what you get
when you perform a pop.
Using the stack so maliciously tampered by Lord Vader,
perform depth first traversal on the graph
shown below, starting from vertex A.
For the traversal, show
(i) the order in which vertices are discovered by
depth first traversal and (ii) the depth first traversal tree.
Assume that the neighbors of each vertex are scanned
in alphabetical order of their names.
