What is an ALGORITHM? From Wikipedia:
In mathematics and computer science, an algorithm (i/ˈælɡərɪðəm/) is an effective method expressed as a finite list of well-defined instructions for calculating a function. Algorithms are used for calculation, data processing, and automated reasoning. In simple words an algorithm is a step-by-step procedure for calculations.
