What is an algorithm, and why it is important in computer science?

An algorithm is a well-defined sequence of steps or instructions designed to perform a specific task or solve a particular problem. In computer science, algorithms are fundamental building blocks for creating software and systems. They are used to process data, perform calculations, automate reasoning, and manage tasks efficiently.

Characteristics of an Algorithm

1. Well-defined Input: The algorithm accepts zero or more inputs.
2. 
   
3. Well-defined Output: The algorithm produces one or more outputs.
4. 
   
5. Definiteness: Each step of the algorithm is precisely defined and unambiguous.
6. 
   
7. Finiteness: The algorithm terminates after a finite number of steps.
8. 
   
9. Effectiveness: Each step of the algorithm is basic enough to be carried out, in principle, by a person using only paper and pencil.
