[Tutor] How to Think Like a Computer Scientist...

[Michael yaV]

The green horn that I am, last week I started to go through the "How  
to Think Like a Computer Scientist" tutorial. I have gotten to Chapter  
3 --Functions' 3.8 Exercises. I think I have the 1st exercise correct  
but I'm really not sure. Is their any answer sheet I can go to to make  
sure i am getting the right answers the correct way?

Thanks for any help, Michael
