38. Professor Chen uses the following algorithm for merging k sorted lists, each having n/k elements. He takes the first list and merges it with the second list using a linear-time algorithm for merging two sorted lists, such as the merging algorithm used in merge sort. Then, he merges the resulting list of 2n/k elements with the third list, merges the list of 3n/k elements that results with the fourth list, and so forth, until she ends up with a single sorted list of all elements. What is the worst-case running time of the professor Chen's algorithm in terms of n and k. (A)θ(log(nk))(B)θ(nk) (C)θ(nlogk) (D)θ(lognlogk) (E)θ(n)

39. A hiker faces the Knapsack problem. There are 7 items to be packed into the knapsack, each with value viand weight wi as shown in the following table. The knapsack, which is initially empty, can hold a maximum weight of 16, so some item(s) must be left behind. The optimality criterion is to maximize the total value of the items that are placed in the knapsack.The hiker fills the knapsack one item at a time. Now consider the following two cases: (a) fractions of items cannot be packed, and (2) fractions of items can be packed. What are the optimal values of the items that are packed in these two cases respectively? Give the answer in the form of (no-fractions-allowed, fractions-allowed). (A)(28,30.5) (B)(37,40)(C)(30,34) (D)(38,40) (E)(34,38.5)

40. Determine the expected search cost of an optimal binary search tree for a set of n = 5 keys with the following probabilities. We assume that all searches are successful. (A) 2.15 (B)1.15 (C)2.10 (D) 1.10 (E) 2.0
