that looks like I am a good candidate for Amazon, lol.

but on a serious note, the good solution is sort of obvious and in general you encounter much more interesting problems on a daily basis, but than again I am working in Clojure where working with data structures is much easier and straightforward than in Java.

I am sorry if that sounds condescending, in reality I question my engineering ability almost every day. There is a lot of things that I know horribly less than any engineer worth their salt.
