Consider the followingfor computing the sum of the first n cubes: S(n) = 13 + 23 + . . . + n3.
ALGORITHM S(n)
//Input: A positive integer n
//Output: The sum of the first n cubes
if n = 1 return 1
else return S(n − 1) + n * n * n
a. Set up and solve a recurrence relation for the number of times the algorithm’s basic operation is executed.
b. How does this algorithm compare with the straightforward no recursive algorithm for computing this sum?
