Definition
Algorithm is a precise sequence of steps or rules designed to solve a problem or perform a computation. Algorithms are fundamental to programming, data analysis, and computer problem-solving.
Why It Matters
Algorithms determine how efficiently a task is performed and how data is processed. Well-designed algorithms reduce computation time, conserve resources, and can solve complex problems that are otherwise infeasible. They are the backbone of software, artificial intelligence, and digital systems.
Example
A simple example is a sorting algorithm like Bubble Sort, which organizes a list of numbers in ascending order by repeatedly comparing and swapping elements. More complex algorithms, such as those used in search engines or pathfinding, perform billions of calculations to deliver results efficiently.
