NEED URGENT HELP

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)
hep plox!

and almost none of the solutions posted in here made use of tail recursion. Tail recursive calls need to look like:


int f(int x) {
  return g(x - 1);
}

this can't be tail call optimized


int f(int x) {
  return x*g(x - 1);
}

It needs to call g, get the return value, and then multiply by x. That multiply by x prevents a tail call, which would, in one way or another, jump to g with x - 1 as a parameter and its return value would go to the caller of f.
