Question

It there anyone familiar with the language racket ? I'm having trouble with this problem

this is what I was able to come up with but I'm completely at a loss.

Any help is highly appreciated

Write the following three functions using Racket. 1. (power base exponent) computes basegonment using the following recursive definition. if n = 0 b" b2) if n0 and n is even (b ),bif n > 0 and n is odd This recursion is significantly more efficient for large exponents than the one discussed in class. However, in order to implement it efficiently, the code can only make one recursive call to compute bi or b. Accomplish this by using let and a lambda expression to define a squaring function within the definition of the function power.

Explanation / Answer

- Error "No language chosen" is because you didn't choose language. Go to Language tab > Choose Language > Racket Language

- Then try to debug your code

- One solution to this problem is :

(define (power base exponent)
(cond ((= exponent 0) 1)   
((even? exponent) (sqr (power base (quotient exponent 2))))
(else (* (power base (- exponent 1)) base))))

Input:

(power 2 3)

Output:

8

Please let me know for further assistance.

Thanks,
