In mathematics, the Fibonacci numbers, commonly denoted Fn , from a sequence, called the Fibonacci sequence, such that each number is the sum of the two preceding ones, starting from 0 and 1. That is: F0=0,F1=1 , and Fn=Fn−1+Fn−2 when n>1. The beginning of the sequence is thus: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, ... Write a python function fib() that takes one argument N and prints the first N terms of the Fibonacci numbers.
