!!! Overview
[{$pagename}] is an [implementation] of an [algorithm].


[{$pagename}] is a [Subroutine] that is independent and __NOT__ associated to a [Class]. (Unlike a [Method])

A typical [{$pagename}] is described by:\\ 

[Dependent variable] = function ([Independent variable])


[{$pagename}] is a combination of instructions that are combined to achieve some result. 

[{$pagename}] typically requires some input (called arguments) and returns some results. 

!! [{$pagename}] [Example]
For [example], consider the example of driving a car. To determine the mileage, you need to perform a calculation using the distance driven and the amount of fuel used. You could write a [{$pagename}] to do this calculation. The arguments going into the function would be distance and fuel consumption, and the result would be mileage. Anytime you want to determine the mileage, you simply call the [{$pagename}].
