COP 5536 Advаnced Dаtа Structures Spring 2023 Exam 1 CLOSED BOOK 8:00 pm – 9:30 pm (60 Minutes + Extra 30 Minutes fоr scanning & submissiоn) PLEASE READ THE FOLLOWING INSTRUCTIONS CAREFULLY Fоr all problems, use only the algorithms discussed in class/text. Write your answers directly on your own blank white paper. You may use extra scratch paper for calculation, but these will not be submitted. Late submissions will not be accepted. Only submissions made using Honorlock will be graded. You will be monitored through Honorlock. In the response sheet, please enter your name and UFID. Submission pdf should be named as _. For example, John_Doe Note. All answers will be graded on correctness, efficiency, clarity, elegance, and other normal criteria that determine quality. Last Name: _____________ First Name: _______________ UFID: _______________ Q. 1 (12) Q. 2 (14) Q. 3 (14) Q. 4 (10) Total (50) Question 1 (12): Consider a stack S with two operations: push(x) and get(k). push(x) adds x to the top of S and get(k) pops (removes) the top k elements from S. The actual cost of push(x) is 1and that of get(k) is k (you may assume that k is between 1 and the number of elements presently in stack so do not need to worry about ‘over-pop’). The stack is initially empty. (a)(8) Derive the smallest integer amortized complexity for push(x) and get(k) using either the accounting method or the potential function method. Your answer should be independent of k. Note that the aggregate method doesn’t apply as the two operations have a different amortized cost. (b)(4) Use the amortized costs derived in (a) to complete the accounting sheet below. Some entries are already filled in. push(x) push(x) push(x) get(1) push(x) push(x) get(2) push(x) get(3) Actual cost 1 1 Amortized cost Potential Question 2 (14): You are given n=1000 records to be sorted on a computer with a memory capacity of S=50 records. Assume that the entire S-record capacity may be used for input/output buffers, i.e., you have extra memory for a k-way loser tree. The input is on disk and consists of m runs. Assume that you use 2k buffers for input and 2 for output. Also, assume that each time a disk access is made, the seek time is ts=10ms, and the latency time is tl=5ms. The transmission time is tt=0.5ms per record transmitted. (a)(6) What is the buffer size, b, and the total input time for phase two of external sorting and merging, if a k-way merge scheme is used? What is the better k with respect to the total input time for phase two? Consider only k=4 and 9. (b)(4) Assume that it takes 0.5 ms to merge 10 records. Compute the total time for phase two of external sorting when k=9, i.e., compute the total time taken for input, merging, and output. (c)(4) We can use either a winner tree or a loser tree for the second phase of the external sort. Which is expected to run faster in practice? Why? Question 3 (14): (a)(6) Perform Remove Min on the following interval heap. Show each step. (b)(6) Perform Remove Max on the same interval heap in (a). Show each step. (c)(2) List any two properties of leftist trees. Question 4 (10): (a)(4)What is the max degree in a binomial heap of n nodes? Justify your answer. (b)(6)Perform a remove min operation is performed on the following Min Binomial heap. Show the resulting Binomial heap. Show each step.
