In an algorithm, there are three fundamental building blocks:Linear Sequence: A continuation of actions or utterances made one after the other is known as a linear sequence.Conditional: A choice is made between two possible courses of action.Loop: Statements in the WHILE and FOR sequences are repeated numerous times.The core of computing is an algorithm. If we look at ourselves, we may see various algorithms at work, addressing the issues we face every day: Algorithms power a variety of applications, including Netflix recommendation systems, social media networks, GPS apps, Google search, and e-commerce platforms.
