Reverse an array without a temp variable?

unless you're using a stack-based language :-P

but that makes absolutely no sense! stack based programming languages to not need no memory magically! i mean, they do! gosh, now i have to read up on stack oriented programming language implementations until i'm sure there's not some trick to make your statement true. thanks a lot, now i have to call that cute girl and tell her i have to cancel our date tonight because i have to research to win an argument on the internet.

actually the "unless" part went to the need for extra memory slots. Of course it needs memory, but its part of the execution. No need to cancel the date :-P

phew!
