If you want to have working code reviewed for improvement, ask at Code Review please. — πάντα ῥεῖ 48 secs ago
Not sure about simpler methods, but a quick review of the code seems to suggest it's probably linear time and thus not much you can probably do to improve it there without some kind of obscure optimization. As for why your questions are getting removed, it's because this isn't really a question suited to SO, it helps a lot if you read and follow the SO rules, would be better here: codereview.stackexchange.com Take a look at this before asking more SO questions to avoid them being removed: stackoverflow.com/help/askingNuclearman 16 secs ago
