Exercise 3 – Solution Q1. No, AB+ = {A,B,C},a proper subset of {A,B,C,D,E} Yes, ABD+ = {A,B,C,D,E} Q2. Let us use the following shorthand notation: C = CourseNo, SN = SecNo, OD = OfferingDept, CH = CreditHours, CL = CourseLevel, I = InstructorSSN, S = Semester, Y = Year, D = Days_Hours, RM = RoomNo,

Problem Set Nine Problem Set Nine Q1 Show how to modify the KPM pattern matching algorithm so as to find every occurrence of a pattern string P that appears as a substring in T, while still running in O(n+m) time. (Be sure to catch even those matches that overlap.) Q2 A pattern P of length

Problem Set 5 Problem Set 5 Problem 1 Show how to implement a stack ADT using only a priority queue and one additional integer variable. Problem 2 Write an algorithm for updating the key of an item in a priority queue, and analyse its time complexity. Problem 3 Given a heap T and a key

Problem Set 3-a Problem 1 Show that if p(n) is a polynomial in n, then log p(n) is O(log n). Problem 2 Show that ∑ 𝑖2𝑛𝑖=1 is O(n 3). Problem 3 Show that ∑ 𝑖 2𝑖 𝑛 𝑖=1 is O(1). Problem 4 Show that ∑ log 𝑖𝑛𝑖=1 is O(n log n). Problem 5 Consider the

Homework Five Problem Set 3-b Solution Problem 1 For each node v in a tree T, let pre(v) be the rank of v in the preorder traversal of T, post(v) the rank of in the postorder traversal of T, depth(v) the depth of v, and desc(v) the number of descendants of v, not counting v
