An algorithm is a set of instructions or a step-by-step procedure used to solve a specific problem or perform a specific task. It is a precise and well-defined sequence of operations that takes some input and produces an output. Algorithms can be implemented in various forms, such as computer programs, mathematical formulas, flowcharts, or pseudocode.
