This is a follow-up on 57. create an Observable.
Suppose you have solved 57. create an Observable, here you are asked to implement a creation operator
From the document,
Creates an Observable that emits sequential numbers every specified interval of time
Above code prints 0, 1, 2 .... with an interval of 1 seconds.
Note Observable is already given for you, no need to create it.
Let's try to solve this problem within 10 mintues.
