Computational algorithms are step-by-step procedures or formulas used to solve problems or perform tasks in computing. They take input data, process it through a series of defined operations, and produce output. Algorithms are essential in various fields, including computer science, mathematics, and data analysis, as they help automate processes and make calculations more efficient. These algorithms can be simple, like sorting a list of numbers, or complex, like those used in machine learning models. They are often implemented in programming languages such as Python or Java, allowing computers to execute tasks quickly and accurately.
