Hands-On Data Structures and Algorithms with Python - Third Edition

By: Dr. Basant Agarwal

Overview of this book

Choosing the right data structure is pivotal to optimizing the performance and scalability of applications. This new edition of Hands-On Data Structures and Algorithms with Python will expand your understanding of key structures, including stacks, queues, and lists, and also show you how to apply priority queues and heaps in applications. You’ll learn how to analyze and compare Python algorithms, and understand which algorithms should be used for a problem based on running time and computational complexity. You will also become confident organizing your code in a manageable, consistent, and scalable way, which will boost your productivity as a Python developer. By the end of this Python book, you’ll be able to manipulate the most important data structures and algorithms to more efficiently store, organize, and access data in your applications.

Performance analysis of an algorithm

The performance of an algorithm is generally measured by the size of its input data, n, and the time and the memory space used by the algorithm. The time required is measured by the key operations to be performed by the algorithm (such as comparison operations), where key operations are instructions that take a significant amount of time during execution. Whereas the space requirement of an algorithm is measured by the memory needed to store the variables, constants, and instructions during the execution of the program.

Time complexity

The time complexity of the algorithm is the amount of time that an algorithm will take to execute on a computer system to produce the output. The aim of analyzing the time complexity of the algorithm is to determine, for a given problem and more than one algorithm, which one of the algorithms is the most efficient with respect to the time required to execute. The running time required by an algorithm depends...
