If you run any of the functions (as opposed to just testing them), comment out the code for running the functions before you submit your solution.
N.B.: Tests are not runs. A test is when you evaluate an expression and compare it to some expected result, while a run is when you evaluate an expression without anticipating any particular result for the expression.
No homework. Really.
Use the time to review
all (did you see the color and the font
of this word?) old homeworks in preparation of the
first midterm.
