Thanks to all for the excellent and quick responses. David - you are right the variable should be called product not sum. This is just some poorly written Java code that I am translating to Clojure.
Justin - thanks for the idea on how to visualize such algorithms and the picture you shared. -----Original Message----- From: clojure@googlegroups.com [mailto:clojure@googlegroups.com] On Behalf Of Alan Malloy Sent: Wednesday, June 29, 2011 4:50 AM To: Clojure Subject: Re: Translating Java code with nested for loops On Jun 29, 12:55 am, Ken Wesson <kwess...@gmail.com> wrote: > On Wed, Jun 29, 2011 at 3:53 AM, Alan Malloy <a...@malloys.org> wrote: > > This layout makes it fairly clear that the first element of total- > > values is never being used, but it would be nice if we could say so > > explicitly.

Not sure if this is what you're pointing out (a single word is tricky to decipher), but I did forget to *use* interesting-values after defining it: it should be the first form in the ->> list. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
