Hi George,

I absolutely agree. It is better of with a non-recursive solution.

>However, in some cases a recursive solution isn't only the best way, it's the only way.

Some say that every recursive routine could be rewritten into a non recursive one. I really did not validate this statement, but I do know that some problems are much better handled recursively.

It seems we are on the same line.
