These are all new to me.  I learned Ruby by skimming the manual for the 
syntax needed to express my C++ thinking in Ruby.  :-)

When I discovered gsub! took a regex, I went back and reread some of the 
String documentation.  I was going to use

line.squeeze ' '

But line.delete is more clear.  I'll probably still use gsub! before it, 
because to my thinking the proper behavior is to throw away all 
characters that aren't digits.  Dono... we're into "proper parsing of 
invalid input" at this point.  I only squeeze the whitespace because I 
was using split() to break up the input.  That may be unecessary (split 
/\s+/) or avoidable (remove all whitespace, iterate over chars).

James, I'll edit the code, because these are nice changes.  I hate to 
spam the list, but I'm assuming that reposting is the preferred way to 
update code for the Quiz, since you simply reference the web archive of 
the post directly?
