Assignments for this course are supposed to be a learning experience. If you are able to complete the assignment successfully, then you have presumably learned what I intended from the experience of working out your solution.

But if you were unsuccessful or only partially successful at the assignment, it's still important that you try to learn from it. The first step in doing so is to return to the assignment submission page and click on the “View Solution” button. You will see not only my solution to the assignment but also the tests that I used for the evaluation. These tests are sometimes simple input files. Other times they are shell scripts that can be executed to run the test.

Study my solution and compare it to your own. Try some of the test data listed there.

If, after doing that, you feel that you understand what was involved, then you are ready to move on. If not, it's time to ask questions.

I'm more than happy to take questions, but if I don't hear from you, I will assume that you viewed the solution and understood it.
