The Fibonacci Sequence and the Golden Ratio
Lucas Numbers: The Missing Link Between Fibonacci and the Golden Ratio The study of the Golden Ratio naturally leads to its close connection with Fibonacci numbers. These two concepts are not merely related by a simple formula—they describe each other in deep, recurring ways. However, there’s a lesser-known yet essential companion to this mathematical relationship:…

Data Structures for Disjoint Sets
Overview Disjoint-set data structures, also known as union-find structures, manage a dynamic collection of non-overlapping sets. They are crucial in problems that involve connectivity and group membership, such as network clustering, image processing, and graph algorithms. The core operations supported are: These operations are designed to be fast—even across large sequences of updates—especially when combined…

Why Computers Think in Binary: The Magic of Bits, Overflow, and Floating-Point Reality
Have you ever stopped to wonder how your computer handles numbers under the hood? What seems like a simple task—adding, subtracting, or dividing—is actually constrained by strict rules and limitations. Unlike humans, computers operate in a world of finite precision and binary logic. In this post, we explore the foundational ideas of binary numbers and…
