In computer programming terms, an algorithm is any well-defined computational procedure that takes some value, or set of values, as input and produces some value, or set of values, as output. An algorithm is thus a sequence of computational steps that transform the input into the output.
Algorithms are widely used throughout all areas of IT. In mathematics and computer science, an algorithm usually refers to a small procedure that solves a recurrent problem. Algorithms are also used as specifications for performing data processing and play a major role in automated systems.
An algorithm to add two numbers :
* Take two number inputs
* Add numbers using the + operator
* Display the result
Qualities of a Good Algorithm :
* Input and output should be defined precisely.
* Each step in the algorithm should be clear and unambiguous.
* Algorithms should be most effective among many different ways to solve a problem.
* An algorithm shouldn't include computer code. Instead, the algorithm should be written in such a way that it can be used in different programming languages.
