What Is an Algorithm?

An algorithm is a set of instructions that are followed to solve a specific problem or accomplish a specific task. Depending on the task, the instructions can be very simple or complex.

In computer science, algorithms are used to solve computational problems, such as sorting data, searching for specific information, or performing mathematical operations.

Algorithms can be expressed in a variety of ways, including natural language, pseudocode, flowcharts, and programming languages. The choice of representation depends on the intended audience and the purpose of the algorithm.
