An algorithm is a well-defined sequence of steps or instructions designed to perform a specific task or solve a problem. It is the foundation of computer programming and computational processes. In essence, algorithms provide a blueprint for solving problems and can range from simple instructions, like making a cup of tea, to complex procedures, such as those found in artificial intelligence and data processing. For an algorithm to be effective, it must be clear, finite, and achievable within the constraints of the programming environment. Algorithms can be represented in various forms, including pseudocode, flowcharts, and code in programming languages. They are essential for creating efficient programs and optimizing the functionality of software applications. Each step of an algorithm should ideally be unambiguous, leading from the initial state to a clearly defined end result.
