best book for algorithms for beginners



But how do you learn algorithms? There are many books on the market that claim to teach you everything you need to know about algorithms. But not all books are created equal. Some are too easy, some are too hard, some are too boring, some are too confusing.


In this article, we will help you find the best book for algorithms for beginners. We will tell you what to look for in an algorithm book, and we will review the top 5 algorithm books for beginners that we recommend. By the end of this article, you will have a clear idea of which book suits your needs and goals.


What to Look for in an Algorithm Book




Before you buy an algorithm book, you should consider some factors that will affect your learning experience and outcome. Here are some of the most important ones:


Level of Difficulty




One of the first things you should check is the level of difficulty of the book. You don't want to buy a book that is too easy or too hard for you. You want a book that challenges you but doesn't overwhelm you.


A good way to determine the level of difficulty of a book is to look at its prerequisites, target audience and reviews. You should also skim through the table of contents, the introduction and some sample chapters to get a feel for the style and depth of the book.


Generally speaking, there are three levels of difficulty for algorithm books: beginner, intermediate and advanced. Beginner books are suitable for those who have little or no prior knowledge of algorithms. They usually cover the basic concepts, techniques and examples of algorithms. Intermediate books are suitable for those who have some background in algorithms and want to learn more advanced topics and applications. They usually cover more complex algorithms, data structures and analysis. Advanced books are suitable for those who have a strong foundation in algorithms and want to explore the cutting-edge research and challenges in the field. They usually cover specialized algorithms, optimization, approximation, parallelism and cryptography.


Some examples of beginner books are Grokking Algorithms by Aditya Bhargava, Algorithms Unlocked by Thomas H. Cormen and Data Structures and Algorithms in Python by Michael T. Goodrich et al. Some examples of intermediate books are Introduction to Algorithms by Thomas H. Cormen et al., Algorithms by Robert Sedgewick and Kevin Wayne and The Algorithm Design Manual by Steven S. Skiena. Some examples of advanced books are Algorithm Design by Jon Kleinberg and Éva Tardos, Introduction to the Design and Analysis of Algorithms by Anany Levitin and The Art of Computer Programming by Donald E. Knuth.


Language Preference




Another thing you should consider is your language preference. Some algorithm books use pseudocode or a generic programming language to illustrate algorithms. Pseudocode is a simplified notation that resembles a programming language but omits some details and syntax. It is useful for expressing algorithms in a clear and concise way that can be easily translated into any programming language.


Other algorithm books use a specific programming language to illustrate algorithms. This can be helpful if you want to learn how to implement algorithms in that language or if you are already familiar with that language. However, it can also be limiting if you want to learn algorithms in a different language or if you are not comfortable with that language.


Some of the most popular programming languages for algorithm books are Python, Java, C++ and C#. Python is a high-level, interpreted, dynamic and multi-paradigm language that is known for its readability, simplicity and versatility. Java is a high-level, compiled, static and object-oriented language that is known for its portability, robustness and performance. C++ is a low-level, compiled, static and multi-paradigm language that is known for its speed, power and flexibility. C# is a high-level, compiled, static and object-oriented language that is known for its productivity, interoperability and modern features.


Some examples of algorithm books that use pseudocode are Introduction to Algorithms by Thomas H. Cormen et al., The Algorithm Design Manual by Steven S. Skiena and Algorithm Design by Jon Kleinberg and Éva Tardos. Some examples of algorithm books that use Python are Grokking Algorithms by Aditya Bhargava, Python Algorithms by Magnus Lie Hetland and Data Structures and Algorithms in Python by Michael T. Goodrich et al. Some examples of algorithm books that use Java are Algorithms by Robert Sedgewick and Kevin Wayne, Data Structures and Algorithms in Java by Michael T. Goodrich et al. and Data Structures & Algorithms in Java by Robert Lafore. Some examples of algorithm books that use C++ are Data Structures & Algorithm Analysis in C++ by Mark A. Weiss, Data Structures Using C++ by D.S. Malik and Introduction to the Design & Analysis of Algorithms Using C++ by Anany Levitin.


Practical Application




The last thing you should look for in an algorithm book is its practical application. You don't want to buy a book that only teaches you the theory of algorithms without showing you how to use them in real-world problems. You want a book that teaches you how to apply algorithms to solve problems and implement them in code.


A good way to judge the practical application of a book is to look at its exercises, projects and examples. You should look for a book that has plenty of exercises that test your understanding, challenge your thinking and reinforce your learning. You should also look for a book that has some projects that allow you to apply your knowledge, develop your skills and create something useful or fun. You should also look for a book that has some real-world examples that illustrate how algorithms are used in various domains such as science, engineering, business, gaming, etc.
