Don't be perplexed by data structures! This fun, friendly, and fully-illustrated guide makes it easy to learn useful data structures you'll put to work every day. Data structures are vital for shaping and handling all of the data an organization processes - that's why they show up in so many IT interviews! But you don't need to be a math expert to understand data structures. This book will prove it. You'll discover the most common and most useful day-to-day data structures through fun examples, engaging industry stories, and hundreds of illustrations. This book teaches data structures to anyone, no matter what their background. You don't need advanced math, you don't need to have taken CS101 or any course; you don't need to be a coding ninja, but some knowledge of Python might help. This book, like every book in the Grooking series, gives you an understanding of how things work: what data structure is, what the basic structures you can use are, and how can you objectively decide which data structure is better for your task. It's a book for beginners, meaning that it assumes no previous knowledge and it leverages your intuition and visual memory, but even if you are familiar with the subject, you might find it useful to dust off and even get a deeper understanding of some of the topics. By the time you've finished reading, you'll be able to spot when a data structure would help your code and know the perfect solution for the problem!
