An algorithm is a set of step-by-step procedures or a list of rules to follow for completing a specific task or solving a particular problem. In computer science, an algorithm works similarly – it is all about writing a set of rules with a finite number of steps that tell the computer how to perform a task. A computer program is essentially an algorithm that indicates what specific actions a machine should execute to carry out any task. Here are some examples of algorithms:

• Addition Algorithm: This algorithm takes two numbers, writes them vertically by aligning by place value, and then adds each column starting from the rightmost column.

• Recipe Algorithm: A recipe is a set of instructions that guide you through the process of cooking a dish. Each step is a part of the algorithm that, when followed correctly, results in a delicious meal.

• Google Search Algorithm: Googles search algorithm is a complex set of rules that determines which web pages are displayed in response to a users search query. The algorithm takes into account factors such as the relevance of the content, the quality of the website, and the users location.

• Dynamic Programming Algorithm: This algorithm breaks a complex problem into a collection of simpler and smaller ones. Then, it solves each of those minor issues only once, storing their solution for later instead of re-computing their solutions again and again.

Overall, algorithms are essential tools for solving problems in a variety of fields, including computer science, engineering, data analysis, finance, and many others.
