Algorithm is a step by step solution for solving any problems. In computer programming the first ABC step to learning and understanding programming first writes Algorithm Before creating any program. Algorithm is same as blue print which helps how to create logic in a programs. Easy meaning of Algorithm is just free hand writing flow of programs and flow of logic in different-2 environment. It is always written in text form not in GUI diagrams called flow chart. Algorithms are used for calculation, data processing, and automated Reasoning. An Algorithm is an effective method expressed as a finite list of well-defined instructions for calculating a function.
