Presentation Transcript

  1. Chapter 12 Sorting Objectives • Upon completion you will be able to: • Understand the basic concepts of internal sorts • Discuss the relative efficiency of different sorts • Recognize and discuss selection, insertion and exchange sorts Data Structures: A Pseudocode Approach with C, Second Edition

  4. 12-2 Selection Sorts • In each pass of the selection sort, the smallest element is selected from the unsorted sublist and exchanged with the element at the beginning of the unsorted list. We discuss two classic selection sorts, straight selection and heap sort. • Straight Selection Sort • Heap Sort • Selection Sort Efficiency • Selection Sort Implementation Data Structures: A Pseudocode Approach with C, Second Edition

  21. 12-3 Insertion Sorts • In each pass of an insertion sort, one or more pieces of data are inserted into their correct location in an ordered list. In this section we study two insertion sorts: the straight insertion sort and the shell sort. • Straight Insertion Sort • Shell Sort • Insertion Sort Efficiency • Insertion Sort Implementation Data Structures: A Pseudocode Approach with C, Second Edition

  35. 12-4 Exchange Sorts • This section discusses the four basic queue operations. Using diagrammatic figures, it shows how each of them work. It concludes with a comprehensive example that demonstrates each operation. • Bubble Sort • Quick Sort • Exchange Sort Efficiency • Sort Summary • Exchange Sort Implementation Data Structures: A Pseudocode Approach with C, Second Edition

Included in this section is a discussion of file merging and three external sort approaches-natural, balanced, and polyphase. • Merging Ordered Files • Merging Unordered Files • The Sorting Process • Sort Phase Revisited Data Structures: A Pseudocode Approach with C, Second Edition
