Write an iterative function power1 to compute xn for n gt 0

Question

Question: This problem considers several ways to compute x_n for some n >= 0.

(a) Write an iterative function power1 to compute x_n for n >= 0.

(b) Write a recursive function power2 to compute x_n by using the following recursive formulation:

x₀ = 1

x_n = x * xn-1 if n > 0

(c) Write a recursive function power3 to compute x_n by using the following recursive formulation:

x₀ = 1

x_n = (x_n/2)2 if n > 0 and n is even

x_n = x * (x_n/2)2 if n > 0 and n is odd
