Transcribed Image Text:Consider the following recursive algorithm. Algorithm *Mystery* A[0..n − 1]) // Input: An array A[0..n − 1] of real numbers if n = 1 return A[0] else temp ← Riddle(A[0..n − 2])     if temp ≤ A[n − 1] return temp     else return A[n − 1] a. What does this algorithm compute? b. What is its input size? c. What is its basic operation? d. Set up a recurrence relation for the algorithm’s basic operation count and solve it. e. What is the efficiency class of this algorithm?
Expert Solution
Check Mark
Step 1

Answer:

Given

Algorithms Mystery (A[0..n-1])

if n=1 return A[0]

else tempRiddle(A[0..n-2])

if temp<=A[n-1] return temp

else return A[n-1]

We need to write the what will do the algorithm so we will see in the more details with the proper explanation.
