COMP 8042
Hassan S. Shavarani
All work should be done individually.
1. (25 points) Modify the the CuckooHashTable class in the CuckooHashing.h file to im-
plement a cuckoo hash, as described in class and chapter 5 of the textbook.
2. (20 points) Complete the implementation of the GetMinDegIndex() and TopologicalSort()
functions in the Graph.h file to implement a topological sort on a graph, as covered in
class and chapter 9 of the textbook.
3. (55 points) Sudoku is a logic-based, combinatorial number-placement puzzle. In classic
sudoku, the objective is to fill a 9 × 9 grid with digits so that each column, each row,
and each of the nine 3× 3 subgrids that compose the grid (also called “boxes”, “blocks”,
or “regions”) contain all of the digits from 1 to 9. The puzzle setter provides a partially
completed grid, which for a well-posed puzzle has a single solution. [Wikipedia]
The goal of this exercises is to develop a solver for a 9× 9 sudoku puzzle using what you
have learned in chapter 10 of textbook (algorithm design techniques). For that matter,
you are allowed to think of any algorithm design technique that fits this problem. You
will need to explain what technique you have chosen and how it had helped you solve
the problem in the source code itself.
Make sure to comment each change in your code clearly so it is easy to see what you have
changed.
Also please do not change the return types of the functions and do not add any cout
calls in the 3 files you submit (you can add them while working on the solution but please
remove them before submission).
- Submit the completed Graph.h, CuckooHashing.h and Sudoku.h files (along with any
other necessary file that you had to implement and use) in a single ZIP file called
A00######.zip to D2L, where A00###### is your A00 number. You do not
need to prepare a report file. You also will not need to submit COMP8042A2Test.cpp
since I will use another hidden test file which is different from this one. Make sure you
test all the corner cases for each problem.
- Important grading point: if your final submission takes more than 2 minutes to run,
your submission will timeout and you will not receive a grade.
