You will do this exercise by yourself, but be quick to ask questions of your instructor, student assistants and classmates as desired.
The problems themselves are already reasonably documented --- don't worry about writing Javadocs on this program but do keep your code clean, well formatted, and understandable.
The specification of each of the problems is in the TwelveProblems project you download from SVN. Write each of the 12 functions in that file. To solve the problems, you will likely have to look up details in your textbook -- not every function you will need is covered in class. The problems have notes indicating what constructs are required to solve them.
If you have questions, consider posting to Piazza (just be sure not to reveal any solutions in any post) --- instructors and other students can answer your questions on Piazza. You can also visit 217 during lab hours or stop by your instructor's office to get help.
All the problems have unit tests which can run to ensure your solution works as expected. Do run the unit tests to help check yourself. However, the unit tests are not designed to be exhaustive - your code has to be correct for all inputs, even ones not specified in the unit tests (i.e., you should come up with .
Commit your project to your individual repository when you are done.
