PROGRAMMING:Kauraz conjecture (exercise 6-11, fundamentals and applications of Python programming, Higher Education Society)

Collatz conjecture, also known as the odd and even normalization conjecture, refers to that for every positive integer, if it is odd, multiply it by 3 and then add 1, if it is even, divide it by 2.
In this way, we can get 1 in the end. Write a program, input a positive integer, print its koalas sequence.
###Input format:
1 positive integer > 1
###Output format:
A comma separated koalas sequence.
###Input example:
```in
five
```
###Output example:
```out
16,8,4,2,1
```
