6.1 Definition Definition: A queue is a linear list in which additions and deletions take place at different ends. It is also called a first-in-first-out list. The end at which new elements are added is called the rear. The end from which old elements are deleted is called the front

Two kinds of data structure Linear: list, stack, queue, string Non-linear: tree, graph

11.1 Binary Search Trees 1.Definition: A binary search tree is a binary tree that may be empty. nonempty binary search tree satisfies the following properties: 1)Every element has a key and no two elements have the same key: therefore,all keys are distinct

Main topics Definition of graphs and some terminology Three common graph representations Some algorithms

9.1 Introduction A priority queue is a collection of zero or more elements. Each element has a priority or value

7.1 Dictionaries A dictionary is a collection of elements each element has a field called key, and no two elements have the same key value. Operations: Insert(x): insert an element with a specified key value Search(k,x): search an element with a specified key

5.1 definition of stack Definition A stack is a linear list in which insertions and deletions take place at the same end. This end is called the top. The other end of the list is called the bottom. It is also called a LIFO(last-in-first-out) list

3.1 Preface 1. data object--- a set of instances or values for example: Boolean={ false,true} Digit={0,1,2,3,4,5,6,7,8,9} Letter={A, B, ....., a,b, ..... Z} NaturalNumber= {0, 1,2, ..... Integer={0,+1,-1,+2,-2,+3,-3,} String={a,, ..... ,aa, ab, ac

The purpose and contents of the course Introduce most used data structures and algorithms Prerequisite of other courses Introduce algorithm analysis Review C++
