********** Problem Notes *********,

Any time that the problems ask you to write pseudo-code, I want you to 
write working programs. The programs should include some representative 
data and be easy to read and should include comments. You can add comments 
to Logo programs using ";". Unless explicit language requirements are 
stated, you may use either of the four languages C, Pascal, LISP, Logo or 
Python in this course. For many short problems, Logo or Python will be the 
fastest language for coding.

As noted in the syllabus, I expect programs to come with printed source 
code and printed sample output. The source code should be comprehensible 
and contain comments.
