/*
 * Fibonacci Series
 * ----------------
 * In mathematics, the Fibonacci numbers, 
 * commonly denoted Fn, form a sequence, 
 * called the Fibonacci sequence, such that 
 * each number is the sum of the 
 * two preceding ones, starting from 0 and 1.
 * 
 * In other words, the previous two numbers
 * are added to get the next number, starting from 0 & 1.
 * 
 * The Fibonacci Sequence is the series 
 * of numbers: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ...
