Week 3 Programming Assignment 2 :-
Write a program to take an input N and print Fibonacci sequence till N
terms.
The Fibonacci sequence is a set of integers (the Fibonacci numbers)
that starts with a zero, followed by a one, then by another one, and
then by a series of steadily increasing numbers. The sequence follows
the rule that each number is equal to the sum of the preceding two
numbers.
