Re^4: Optimizing a double loop

I'll give it a try. BTW, I will also need to sort the array (by abs values) now.

UPDATE: There's no real to use $full[$_] += $count; instead of $full[$_] = $count;, is there? we can therefore also drop the initialization of @full, can't we?

You're right on both accounts. I just used `+=` because from reading your initial question I wasn't sure if you needed absolute values, or add them to an existing array.	[reply] [d/l]

Thanks! Your suggestion proved to be a brilliant idea. I got a five-fold improvement in running time! Thanks so much! (and sorry for all the exclamation points, I'm just excited!)	[reply]
