Due: 4/14 CS526 Homework Assignment 9 The goal of this assignment is to give students an opportunity to observe differences among three data structures in Java – HashMap, ArrayList, LinkedList – in terms of insertion time and search time. Students are required to write a program that implements the following pseudocode: create a HshMap instance

Data Structures and Algorithms Chapter 8 General Trees Basics • Agraphisasetofnodesandasetofedges. • Formally, a graph G = (V, E), where V is a set of nodes (or vertices) and E is a set of edges. • Each edge connects two nodes, and is represented as (u, v), where u and v are nodes. • A
Data Structures and Algorithms Chapter 9 Priority Queues • Each element in a queue is associated with a key. • When an element is removed, an element with a minimal (or maximal) key is removed. • Usually keys are numbers. • Objects can be used as keys as far as there is a total ordering
