Finding the remainder in Swift is a simple idea that becomes very powerful once you understand it. The remainder tells you what is left after one number is divided by another. In Swift, this is done using the modulo operator, which is written as the percent sign. Even though it looks small, this operator is […]

Multiplying numbers in Swift is one of those basic skills that opens the door to many real programs. Even though multiplication feels simple from school days, it plays a big role in software. Swift uses multiplication when calculating totals, prices, scores, sizes, and many other values. In everyday apps, multiplication appears more than beginners expect.

Division in Swift is one of the core math operations every beginner must understand. It helps you split values into equal parts and find averages, ratios, and rates. Even though division feels familiar from school, learning how Swift handles it is very important because programming follows strict rules. In real applications, division is everywhere. It
Learning how to add two numbers in Swift is one of the first and most important steps for any beginner. Even though addition sounds very simple, it teaches you how Swift works with values, variables, and basic logic. These ideas are the foundation of everything you will build later, from small school projects to real

Subtracting numbers in Swift is another core skill every beginner must learn early. Subtraction helps you understand how Swift works with values, variables, and math operations. Even though it feels simple, it is used everywhere in real programs, from tracking remaining balance to calculating differences in scores or time. In real applications, subtraction appears more

Breadth-First Search, known as BFS, is one of the most important algorithms for exploring graphs and trees. While DFS goes deep into one branch before returning, BFS takes a much wider and more organized approach. It explores nodes level by level, almost like waves spreading out from a starting point. Because of this behaviour, BFS

Fibonacci Search is one of those algorithms that feels both clever and refreshing. It takes the popular idea of searching through sorted data and adds a mathematical twist by using the Fibonacci sequence to decide where to check first. If you’ve ever used Binary Search, you already know the general idea of dividing the data

Depth-First Search, often called DFS, is one of the most important graph-traversal algorithms in computer science. It explores a graph or tree by going as deep as possible into one path before stepping back and exploring the next. This creates a natural “diving” effect where the algorithm tries to reach the deepest node before returning

Exponential Search is a powerful searching technique that combines the speed of doubling steps with the precision of Binary Search. It is designed for sorted arrays and works by jumping through the data in growing steps until it finds a range where the target might be. Once that range is discovered, it hands the job

Jump Search is one of those algorithms that feels simple once you understand the idea behind it, yet it offers a nice step up from basic searching techniques. In many ways, it sits between Linear Search and Binary Search, borrowing ideas from both. It keeps the data sorted like Binary Search does, but it moves
