An algorithm is a step-by-step procedure or formula for solving a problem or completing a task. It provides a clear set of instructions that can be followed to achieve a specific outcome. Algorithms are used in various fields, including computer science, mathematics, and everyday decision-making. In computer programming, algorithms are essential for creating software applications. They help computers process data, perform calculations, and make decisions. For example, a search algorithm helps find information quickly on the internet, while sorting algorithms organize data efficiently. Understanding algorithms is crucial for developing effective solutions in technology and beyond.
