Overview
The final exam is comprehensive will cover all material from the
beginning of the semester through the end but with some emphasis on
material covered since Test 2. The final is more
comprehensive than Test 2 was. This material includes
everything discussed in lectures and covered in assignments. You should
know concepts (e.g. what an AVL tree is, how Dijksra’s algorithm works)
as well as syntax. You may be asked to write, analyze, and/or debug
code.

Example Questions
- Which of the six search algorithms we discussed have O(n^2)
complexity?
- Why is quicksort preferred over mergesort?
- Which type of probing (double, linear, quadratic) allows a higher
load factor before the hash table needs to be rebuilt?
- Which class of integers are good lengths for hash tables? Why?
- Given the hash table below using probing, a hash function
h(x) = x % 7
, and a quadratic conflict
resolution strategy, which index does the value x=27
end up
in?

- Write the depth-first search order of the above graph starting with
A when the adjacency list is in alphabetical
order.
- Write the breadth-first search order of the above graph starting
with A when the adjacency list is in alphabetical
order.

- Does a path in the minimum spanning tree give the shortest distance
between between any two nodes?
