Consider the following recursive algorithm.
ALGORITHM Riddle(A[0..n-1])
//Input:AnarrayA[0..n -1]of real numbers
if n =1 returnA[0]
else temp+Riddle(A[0..n-2])
if temp ≤ A[n-1] return temp
else returnA[n-1]
a. What does this algorithm compute?
b. Set up a recurrence relation for the algorithm's basic operation count and
solve it.
