# Book recommendations for self studying Data Structures in depth in an elegant manner

I am a student from CS background. I am currently going through "Introduction to Algorithms" By Cormen et. al.

$$\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad$$

It is indeed a classic and a master-piece from the four authors. Each and every algorithm in it is written in the simplest manner possible. Each and every algorithms have analysis involved in a hardcore manner. Thought it is a fantastic book on algorithm design and analysis and many sources recommend it for data structures as well but I find that the data structures section is quite less in the above book.

I have gone through the data structure book below :

$$\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad$$

Data structures using C and C++ by Tanenbaum et. al

Though the above book deals with the various topics of data structure I found that many of the implementations of the data structures and their manipulation algorithms have been made unnecessarily complex and it took quite a lot of time to understand certain pieces of codes which otherwise could have been written in a much more elegant manner. This makes it difficult to recall the algorithms in the text which is far beyond intuition at some places. Though the book contains algorithms of the data structure manipulations but at most places the hardcore analysis is missing.

So could any one recommend me a book on data structure which is as elegant as CLRS , simple and lucid, which would help me for myself study. Even if it does not revolve around any particular programming language - it is fine, but if it does it would it be good if the language is a modern one and not the older ones like PASCAL, FORTRAN,... (although even in CLRS 2nd edition they follow the PASCAL like pseudo-code structure, but it is fine as long as it does not go into the nicks and nacks of the features special to these vintage languages)

• What about doing a course in Coursera? Jul 3 '20 at 15:42
• yes you can consider as none can beat the knowledge acquired from a video lecture series and the corresponding book followed in the video lecture series, it lasts forever. As you are having an instructor whom you can play or pause or rewind if you cannot understand the topic. However the corresponding book followed by the instructor is definitely required for greater in-depth everlasting knowledge. If you only watch video lecture, you shall understand the things at great depth , but it stays only temporarily and then you forget. For an everlasting effect, frequent brush up is required I hope Jul 3 '20 at 17:01

You might find Data Structures and Algorithm Analysis, by Clifford A. Shaffer, to be helpful. There are versions for C++ and Java available. (The 3rd edition is old already [2013], and the prior editions were titled A Practical Introduction to Data Structures and Algorithm Analysis.)

It does get very in-depth into the field, including the mathematics involved in analysis and proofs. That said, however, my first read through it (2nd Ed.) was very helpful in many ways, and I didn't then know anything about C++.

As a 2013 book, some of the coding might be in a style or format which is no longer considered "best practice." This is likely more true for the manner in which Object Oriented Programming is utilized than for the syntactical style. The material, discussion, and analysis are still as valid as ever.

The link above is to the author's page where the PDF versions are available, along with many resources to accompany the book. Of course, if you must have a dead-tree version, they are still available, new and used, from places such as Amazon.

The author has stopped updating the PDF and print versions of the book in favor of an online version. I have not experimented with the online version, although a quick peek at it leads me to believe that it is available for "in-class" use and for independent study. As such, it might be more useful to you than the PDF version.

As a caution, I've also seen a 4th Edition with the same title, but by a different author. It may, or may not, be an updated version of the same book, done with the original author's help and blessings. Having never read the 4th Edition I cannot say if it's connected at all.

To give a better idea of the content, and layout, of the book, I am listing an abridged version of the books Table of Contents.

At my school we do use Carrano and Henry, Data Abstraction & Problem Solving with C++: Walls and Mirrors.

The Walls and Mirrors series has been in publication since 1986, and over the years has seen editions in Pascal, Modula-2, C++, and Java. (Most recent editions in C++.) In 2018 it won the McGuffey Longevity Award ​for​​ ​textbooks whose excellence has been demonstrated over time.
