# Recursion 
# Def: "...is a method where the solution to a problem depends on solutions to smaller instance of the same problem.." - wiki
# TL;DR: a function that calls itself inside its body. 

# Recursive programs - Pseduocode 
function factorial: 
input: integer n such that n >= 0
output: n * (n-1) * (n-2) * ... * 1 = n!

    1. if n is 0,   return 1 
    2. else,        return ( n * factorial(n-1) )

Cheatsheets are an excellent complement to other information sources like Linux man-pages, Linux help, or How-To’s and tutorials, as they provide compact and easily accessible information. While man-pages and detailed tutorials often contain comprehensive explanations and extensive guides, cheatsheets summarize the most important options forthe command recursion in a clear format. This allows users to quickly access the needed information for recursion without having to sift through lengthy texts. Especially in stressful situations or for recurring tasks, cheatsheets for recursion are a valuable resource to work efficiently and purposefully.
