Pitcher Problems: A Case Study in Using Search Trees

1. The problem
2. First: Do it by hand
3. Second: Notice what you did
4. Third: Identify the problem type
5. Formalize the Algorithm
6. Pseudocode
7. An edge case leads to a refinement
8. Towards Python: A little OOP
9. Further towards Python: Pseudocode translation
10. Debugging is_goal()
11. Interlude: Bitwise operations (really just &)
12. Back to our program: is_goal()
13. Final program
