We have covered an enormous amount of
material this semester, but the exam can only contain basic questions about a
small fraction of it. When you study, you should focus on understanding basic
issues, not memorizing details. For each algorithm, you should make sure that
you understand how it works on typical input and then ask yourself some
basic questions: Why do we care about this algorithm? How is it different from
other algorithms for the same problem? When is it effective?
The exam will stress material covered since the midterm,
including the following components.
The midterm itself is fair game (did you take the time to understand
questions that you missed on that exam?).
Also, some material before the midterm is also relevant to
putting new algorithms in context. For example, you
might see a question on sorting/searching that covers both
standard and string algorithms.
- Lectures 13–24.
- Algorithms in Java, 4th edition, Chapters 4–6.
- Exercises 13–23.
- Programming assignments 6–8.
Partial list of topics covered since the midterm
||LSD string sort
||MSD string sort
||3-way string quicksort
|Knuth-Morris-Pratt substring search
||Boyer-Moore substring search
||Rabin-Karp substring search
|RE to NFA
||Ternary search tries
Questions that show awareness of advanced topics that were covered in lecture
are also fair game (for example, NP-completeness and 3-satisfiability).
