Thank you all for your kind replies! And to those saying how I should
really use awk for this job- I know, I was just curious! I am very
impressed by the variance in answers, and how different J really is
compared to other languages.
Thanks again,
Lee
P.S. As for the input, just numbers was fine. I'm curious though what
J does when it encounters strings (and numbers!). I figured reading
through the books offered on the wiki will explain this. (+/ "hello"
"world" 100 = what? :)
