An algorithm is a procedure used for solving a problem or performing a computation. Algorithms act as an exact list of instructions that conduct specified actions step by step in either hardware or software based routines.
Algorithms can be expressed as natural languages, programming languages, pseudocode, flowcharts and control tables. Natural language expressions are rare, as they are more ambiguous. Programming languages are normally used for expressing algorithms executed by a computer.
Algorithm Visualizer is a web application that visualizes algorithms in a simple and easy to understand way. It is a tool that helps you to understand how algorithms work and how they can be implemented in code.
