Last Name: _____________ First Name: _______________ UFID: _______________ Q. 1 (10) Q. 2 (12) Q. 3 (14) Q. 4 (14) Total (50) Question 1 (10): We have an n-bit counter that is incremented m times. The counter starts at 0 and each increment increases the counter by 1. The cost to change the kth bit (from the right end) of the counter is 2k (for the rightmost bit, k=0). As an example, in the increment 001011 => 001100, bits 0, 1, and 2 get changed. So, the cost of this increment is 20+21+22 = 1 + 2 + 4 =7. What is the smallest amortized cost of an increment? Use the aggregate method to derive your answer. (Hint: The amortized cost of an increment is a function of the number of increments m.) Question 2 (12): (a)(6) Insert 90 into the interval heap shown below. Show each step.(b)(6) RemoveMin from the original interval heap. Show each step. Use the algorithms discussed in class. Question 3 (14):You are given 7 runs that have 100, 300, 400, 500, 700, 800, 900 equal-length records. The 7 runs are to be merged into one, using a loser tree. It takes 2 seconds to read or write one block from/to disk, and it also takes 1 second of CPU time to merge one block of records. Assume that all input, output, and CPU processing is sequential and there is no waiting time. The block size is 100 records. (a) (7) Give an optimal 4-way merging scheme to merge the 7 runs into 1.(b) (7) What is the total time taken by the optimal scheme? Show the steps. Question 4 (14): (a)(11) Perform the following operation sequence on an initially empty min binomial heap. Show each step.Insert(5), Insert(9), Insert(3), Insert(20), Insert(6), Insert(16), RemoveMin, RemoveMin, Insert(24), Insert(11), RemoveMin. (b)(3) Let s(x) be the length of the shortest path from x to an external node in the subtree rooted at x. What is the minimum number of internal nodes in a leftist tree whose root has the s value s(root)? Proof is not needed.
