Code to reverse a HEX value and convert to Decimal

I have no reason to explain myself to you, you're an arrogant POS, but I'll be brief.

Never said it was difficult, just said I couldn't do it.

Or program an Arduino to do it rather.

Why don't you go try screw a female/male/whatever instead of being a condescending dick? It might loosen you up.

Unless that's not an option for you, in that case I'm sorry you're such a wanker.
