3)The Complete Linked List Roadmap: 10 Algorithms from Beginner to Expert (2026 Guide)

by

“Arrays are for storing data. Linked Lists are for manipulating references.” Arrays are static; Linked Lists are dynamic. If you want to work on Blockchains or Low-Level Memory Management (like inside the Linux Kernel), you must master pointer surgery. This guide covers the 10 Essential Linked List Patterns that separate “Code Monkeys” from “Software Engineers.” … Read more

4)The Complete Stack & Queue Roadmap: 8 Algorithms from Beginner to Expert (2026 Guide)

by

“Stacks and Queues are the traffic lights of Computer Science.” They control the flow of data. Without them, recursion wouldn’t exist (Call Stack), and the Internet wouldn’t work (Packet Queues). While the operations (push, pop) are trivial, the applications are complex. This guide covers the 8 Essential Patterns that bridge the gap between “Junior Developer” … Read more
