sup /prog/

Ive asked this everywer already but peopl seem too lame to make even a simple program like so i hope the mighty anon programers of 4chan are more skilled

what im trying to do is to Write a method taking two parameters x and n that computes the nth power of x without using ^ or declaring a new variable inside the method or using Math lib.
and it has to be coded in JAVA (i know it sux but dont ask why i use dat shit)

Technically, the C code might already be tail-recursion optimized because it has no tail...?

btw has anyone got a legit example use for tail recursion... I've not seen many, but it always seems to be getting used when it's not really necessary in the first place..?

Eg. fib sequence doing every last node when you only need to do n + (n-1) for n steps...?
