Data Structures and Algorithms: Coding Cheatsheet: The DSA Takeover Edition (Coding Interview Patterns)

Interesting book

Incorrect and Scam - kindle edition is only 26 (of 325) pages but costs a full $9.99 - "preview" only mentioned inline - also poor layout, looks like screenshots taken on a 1999 website.

I got this book on a recommendation, so I didn't read the product description. I don't think I should have to read the description to find out that the kindle version is a tiny fraction of the paperback. And since I flipped through more than 15% of its 26 pages, I don't have the option of a refund. It's only $10, but come on. Why not just have the whole book digital? Why sell this under the same listing if it's that different?

Just look at all the other books this author puts out. They are clearly just trying to take people's money. The cheatsheets are often wrong which defeats the whole point

To be honest, this book just isn’t worth the money. The print quality is pretty poor, and there are mistakes that you really wouldn’t expect from a reliable resource. In just the first few pages, I came across two major errors: 1. The book claims that the space complexity of Linear Search is O(N), when it’s actually O(1). 2. It misrepresents the core concept of Binary Search, directing readers to search the left half of the array if the target is greater than the middle element, when it should clearly be the right half. These are mistakes that will likely get you laughed out of your technical interview. Ironically, the book’s own Binary Search code is implemented correctly, which only makes the written explanation look worse. Given these mistakes I didn't even bother with the rest of the book and I can’t help but question all the glowing five-star reviews. I’m not too bothered by the print quality, but for 31 euros, I at least expect accurate information. I’ll be returning this.

The typesetting is awful, it's as if they printed a webpage into a book. There is no forward, or good narration on what they are trying to present - it's like someone's obsidian notebook was sent straight to the printers.

DSA Coding Cheatsheet is a concise and practical resource that helped me strengthen my grasp of fundamental Data Structures and Algorithms. I have a strong hold on arrays, linked lists, stacks, queues, hashing, and strings, and I found the explanations in these sections clear, well-structured, and easy to apply. The book presents these techniques in a way that makes quick revision and problem-solving much smoother. For anyone preparing for coding interviews or assignments, this cheatsheet serves as a reliable companion. It covers the essentials without unnecessary complexity, making it a great tool for brushing up on core concepts.

I recently read DSA Coding Cheatsheet and found it extremely helpful for strengthening my fundamentals, especially in Linked Lists. The book explains concepts in a very concise and structured way, making it perfect for quick revision before interviews or coding practice. The Linked List section clearly explains the difference between arrays and linked lists in terms of memory allocation and access time. I particularly appreciated the explanation of Singly, Doubly, and Circular Linked Lists along with their time and space complexity comparisons. The Fast and Slow Pointer technique was explained in a simple manner, which helped me better understand how to detect cycles and find the middle of a linked list efficiently. The complexity tables and key coding patterns make it easy to remember when operations take O(1) and when they take O(N). Overall, this book is very useful for building clarity in DSA concepts and improving problem-solving confidence for technical interviews. Also it is a very good book for revision one day before placement assessment

Data Structures and Algorithms: Coding Cheatsheet: The DSA Takeover Edition is a compact book made mainly for coding interview preparation. It explains important DSA topics in a clear and short way, with code examples and time complexity details. The book is easy to read and good for quick revision before exams or interviews. However, it does not go very deep into concepts, so it’s better used as a revision guide rather than for learning DSA from scratch. Overall, a helpful and practical cheatsheet-style book for students preparing for coding rounds. It also helped me to get a strong hold on Array, Linked List, Binary Search, Stack, Queue, Graphs.
