Write function collatz () that takes a positive integer x as input and prints the Collatz sequence starting at x. A Collatz sequence is obtained by repeatedly applying this rule to the previous number x is the sequence: Please use simple python

{ x/2 if x is even 3x+1 if x is odd

Your function should stop when the sequence gets to number 1. Not: It is an open question whether the Collatz sequence of every positive integer always ends at 1.
