Thanks for your comments, Chuck & Josh!

The purpose of the assignment is to examine the timing results and 
explain why they differ between programming languages, whether they 
follow the theoretical timing complexity (mostly they do, other than the 
size 128 array, which in both Java and Ruby seems to often be either too 
high or too low), and if not why it might be offset from the theoretical 
complexity.

My goal isn't to make the Ruby code fast, but simply to compare 3 
different languages. I was just a little concerned that I'd done 
something wrong in my Ruby implementation when it was almost two orders 
of magnitude slower than Java. From what you guys said, however, it 
sounds like I'm just comparing marathon times for 2 marathon runners and 
a sprinter.

I really appreciate the suggestions regarding improvements in the code, 
but the program has to be as close to identical as possible across the 
three languages, barring only syntactical differences. I'll definitely 
look your suggestions over to improve my understanding of Ruby, however.

Josh, thanks in particular for pointing out why Ruby would be so much 
slower than Java and C#.
