{ "item_title" : "Arrays - Volume 3 - Swift Edition", "item_author" : [" Flannan P. Brody "], "item_description" : "Stop memorizing array solutions. Start seeing why they work.Arrays - Volume 3 - Swift Edition teaches 57 array algorithms through plain-language explanations, Swift implementations, and step-by-step visual walkthroughs. Four primers - matrix fundamentals, prefix and suffix sums, edge cases and validation, and a repeatable way to approach any array problem - set up the two-dimensional thinking inside. Every algorithm is shown in full color, so pointers, windows, and changing values stand apart at a glance and are easy to trace.Watch a matrix rotate layer by layer. Follow a search through a sorted grid. See connected components spread across a grid, and track the best path as it builds cell by cell. Instead of holding every changing index in your head, follow the execution on the page.The visual walkthroughs use small multiples, a data visualization technique that presents successive stages of an algorithm as a series of consistently structured diagrams. By seeing meaningful stages together, you can compare states, follow what moves, and understand how each decision affects the next. This brings the algorithm to life, reinforcing understanding and helping the underlying patterns and mechanics stay with you longer.Every main algorithm is presented in three complementary parts: Understanding & Reasoning: Learn the goal, key idea, edge cases, and time and space complexity before studying the implementation.Inspect & Debug: Examine Swift code alongside an AI-Era Interview Lens that challenges you to question assumptions, recognize plausible mistakes, and explain why a solution is correct.Trace & Walkthrough: Follow the input through intermediate states to the result, with visual explanations of the decisions that matter.The eight pattern families cover Number Theory & Bitwise Techniques; Number Representations; Dates & Clocks; Matrix Traversal & Transformation; Matrix Search & Validation; Grid Traversal & Connected Components; Grid Paths & Optimization; and Geometry & Simulation.Arrays look like the simplest structure in computer science - right up until one off-by-one index turns a working loop into a wrong answer. This book is about building the instincts that keep every index honest.Every code sample was compiled, tested against edge cases beyond what's printed on the page, and independently reviewed before making it into the book.Designed for readers with basic Swift knowledge who want to strengthen coding interview preparation, debugging, and algorithmic reasoning.This is Volume 3 of the three-volume Swift Arrays collection. All of its algorithms and primers are also included in Arrays - Complete Edition - Swift Edition.Understand the idea. Follow the state. Explain the result.", "item_img_path" : "https://covers1.booksamillion.com/covers/bam/9/79/818/289/9798182899512_b.jpg", "price_data" : { "retail_price" : "49.95", "online_price" : "49.95", "our_price" : "49.95", "club_price" : "49.95", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
