Learn Java Data Structures & Algorithms Visually - Volume 2 - Trees, Linked Lists, Strings & Arrays - 108 algorithms inside

Nov 1, 2026

Uploaded by Putri

Aimed at making data structures and algorithms easier to learn and reason about, the volume compiles 108 Java algorithm entries focused on trees, linked lists, strings, and arrays. Each entry preserves a complete set of understanding and verification materials, including step-by-step reasoning, inspection and debugging, and trace walkthroughs. Editorial and production notes describe how the book was assembled from multiple Java sources and how layout and checks were performed, clarifying what was verified and what was not.

Thank you to the early readers who worked through chapters and told us honestly whichpages clicked and which ones didn't.That feedback shaped the visual language of thisbook as much as anything else did. On a personal note,thank you to my family and friends for the support along the way:Tom&Brid Casey,Mary &Mattie Mclnerney,Brian&Michelle Casey,Declan,Adrian,&Finbar Brody,Stephanie &Jake Pearlman,Shridhar Reddy,and Elaine,Alan,Sandra,&Karen-Ann Casey. Thank you to everyone who has ever had to debug a subtle boundary condition ormissing edge case at 2 a.m.,and wished the textbook diagram had just shown one morestep.This book is for you. Finally,thank you for picking this book up.We hope it makes data structures andalgorithms feel less like something to memorize and more like something you can see. # ABOUT THE AUTHOR Flannan P.Brody is a software engineer with over 18 years of experience buildinglarge-scale systems at companies including Google,Apple,Disney+,and Genentech.Agraduate of the Dublin Institute of Technology,he has navigated the high-stakestechnical interview loops of the world's most selective tech companies more times thanhe'd care to admit. Learn Algorithms Visually was born directly from those repeated cycles.Every return tothe interview circuit brought a deeper layer of clarity,stripping away academic abstraction to reveal how algorithms actually function under the hood.This series is hisattempt to compress years of hard-won insight into a single,intuitive pass. When he isn't drawing algorithms or writing code,he's usually playing soccer ortraveling.

FAQs

What topics does Volume 2 cover?

It focuses on trees, linked lists, strings, and arrays, with multiple algorithm patterns and variations organized across the volume.

What materials are included for each algorithm entry?

Each selected entry retains its full Understanding & Reasoning, Inspect & Debug, and Trace & Walkthrough page set.

Was this compiled volume fully re-verified with a new Java compiler run?

No. The technical verification section states this edition has not undergone a new Java compiler run or a full correctness audit, and the original source verification statements do not establish fresh verification for the compilation.
