Data Structures

A concise, illustrated guide to algorithms and data structures, perfect for coding interviews, classes, or self-study. Covers key concepts, from fundamentals to graphs, trees, sorting, and search techniques.

Build a working SQL database engine in C++20 -- from raw pages to a realquery executor -- one compilable, measured challenge at a time. Everyperformance claim is a benchmark you run yourself; every unit ends with areal bug, caught red-handed and fixed. Nothing asserted. Everythingdemonstrated.

Start with no experience and build the skills to write modern C++ with confidence. From your first program to advanced C++26 features and professional software design, this guide explains every step with clear examples and practical insights. Learn it once, keep it as a reference for years.

After 1,000+ interviews, I kept seeing the same gaps: engineers who use shared_ptr daily but can't explain the control block; developers who write multithreaded code without understanding the memory model they're relying on. This book is the resource I wished existed. Free preview includes Chapter 3: OOP & Polymorphism — the chapter that eliminates more candidates than any other.

This book teaches string and data structure algorithms the way engineers actually reason through them: one character, one pointer, one decision at a time. Every pattern inside is shown three ways — a plain-language explanation of what it does and why, a real working C# implementation you can compile and run yourself, and a full pictorial walkthrough that traces the index, the window, the stack, and the trie through every step.

Strings - Beginner → Intermediate → Advanced - C++ Edition brings both volumes together: 102 string algorithms taught through plain-language explanations, C++ implementations, and step-by-step visual walkthroughs that trace the... Printed in full color.

A practical interview reference covering Modern C++ language features, STL usage, concurrency, and performance (553 manuscript pages).

Go beyond C++ syntax and learn to use the STL with confidence. Explore containers, algorithms, iterators, ranges and more through practical examples, performance insights and real-world patterns. Build a deeper understanding of how the STL works, when to use each tool and how to write cleaner, faster and more maintainable C++.

Distributed systems can feel overwhelming until you build one yourself. This book takes you from core networking and concurrency concepts to a complete production-ready platform in Go. Every chapter adds real working code so you learn not just the theory but how reliable systems are built and run at scale.

Stop being a syntax typist. Master Clean Code Architecture and Algorithmic Thinking to become a professional Software Architect in 2026. This blueprint teaches you to build Scalable Systems using Binary Logic, Big O Notation, and proven Software Engineering Patterns. Perfect for the modern Backend Developer, self-taught coder, and Tech Entrepreneur looking to design high-performance software from scratch.

What really happens inside a database file? Learn to read binary data like a map, uncover hidden structures and turn raw bytes into a working understanding of how storage engines work. With hands-on examples from SQLite, PostgreSQL, InnoDB and more, this book shows you how to reverse engineer unfamiliar formats from the ground up.

Discover what makes Racket more than just another programming language. Mastering Racket takes you from the fundamentals to macros, concurrency, web development and custom language design through practical, runnable examples. Learn to think in Racket and unlock the ideas that make it such a powerful tool for building software.

Recursion, Backtracking & Dynamic Programming - C++ Edition teaches 50 recursion, backtracking, and dynamic programming algorithms through plain-language explanations, C++ implementations, and step-by-step visual... Printed in full color.

A book designed to help you transition from merely knowing Python to cracking Leetcode patterns. This book explains core DSA concepts through clear, intuitive analogies and walks you through the most important Leetcode patterns. If you're aiming to ace your next coding interview, this is the book I wish I had when I started.

This book revolutionizes your programming skills with meticulously solved challenges, practical strategies, and expert insights. From beginners to pros, master complex problems, write clean code, and ace interviews. Elevate your coding prowess and become a true champion!
