Write a recursive function, power, that takes as parameters two integers and y such that z is nonzero and returns ". You can use the following recursive definition to calculate z". If y 0: power(x, y) if y=0 if y=1 1x power(r, y-1) if y> 1 Write a recursive function, power, that takes as parameters two integers and y such that z is nonzero and returns ".
