a. Design a recursive algorithm for computing 3n for any nonnegative integer n that is based on the formula 3n = 3n−1 + 3n−1 + 3n−1 b. Set up a recurrence relation for the number of additions made by the algorithm and solve it. c. Draw a tree of recursive calls for this algorithm and count the number of calls made by the algorithm. d. Is it a good algorithm for solving this problem?
