Python Data Structures and Algorithms

By: Benjamin Baka

Overview of this book

Data structures allow you to organize data in a particular way efficiently. They are critical to any problem, provide a complete solution, and act like reusable code. In this book, you will learn the essential Python data structures and the most common algorithms. With this easy-to-read book, you will be able to understand the power of linked lists, double linked lists, and circular linked lists. You will be able to create complex data structures such as graphs, stacks and queues. We will explore the application of binary searches and binary search trees. You will learn the common techniques and structures used in tasks such as preprocessing, modeling, and transforming data. We will also discuss how to organize your code in a manageable, consistent, and extendable way. The book will explore in detail sorting algorithms such as bubble sort, selection sort, insertion sort, and merge sort. By the end of the book, you will learn how to build components that are easy to understand, debug, and use in different applications.

Chapter 10. Sorting

Whenever data is collected, there comes a time when it becomes necessary to sort the data. The sorting operation is common to all datasets, be it a collection of names, telephone numbers, or items on a simple to-do list.

In this chapter, we'll study a few sorting techniques, including the following:

  • Bubble sort
  • Insertion sort
  • Selection sort
  • Quick sort
  • Heap sort

In our treatment of these sorting algorithms, we will take into consideration their asymptotic behavior. Some of the algorithms are relatively easy to develop but may perform poorly. Other algorithms that are a little complex to write will show impressive performance.

After sorting, it becomes much easier to conduct search operations on a collection of items. We'll start with the simplest of all sorting algorithms--the bubble sort algorithm.
