Think Data Structures: Algorithms and Information Retrieval in Java

by Allen B. Downey

If youíre a student studying computer science or a software developer preparing for technical interviews, this practical book will help you learn and review some of the most important ideas in software engineeringódata structures and algorithmsóin a way thatís clearer, more concise, and more engaging than other materials.

By emphasizing practical knowledge and skills over theory, author Allen Downey shows you how to use data structures to implement efficient algorithms, and then analyze and measure their performance. Youíll explore the important classes in the Java collections framework (JCF), how theyíre implemented, and how theyíre expected to perform. Each chapter presents hands-on exercises supported by test code online.

Use data structures such as lists and maps, and understand how they work Build an application that reads Wikipedia pages, parses the contents, and navigates the resulting data tree Analyze code to predict how fast it will run and how much memory it will require Write classes that implement the Map interface, using a hash table and binary search tree Build a simple web search engine with a crawler, an indexer that stores web page contents, and a retriever that returns user query results Other books by Allen Downey include Think Java, Think Python, Think Stats, and Think Bayes.

Practical introduction to most used data structures in normal day to day with analysis and implementation details

[Miguel Arvelo · Rating 3 out of 5]

Good enough for refreshing the material

I have to admit I did not do the web crawler project as I was just interested in the concepts. A novice might find the exercises helpful, but I didn’t. A very sad decision made by the author was to focus a lot of the content on tools specific for the web crawling project. I enjoyed the first chapters and skimmed the last few ones.

много опечаток. перевод странный

[Srinivasan Nanduri · Rating 3 out of 5]

An opinionated and deficient explanation of the subject

[Xianshun Chen · Rating 2 out of 5]

This book is definitely just for beginner. On the same topic, i would recommend "Introduction to Information Retrieval" and "Algorithms" instead.
