+# The Collatz Conjecture is a famous math problem. 
+# The conjecture is that after applying a sequence of one of two transformations, 
+# every positive integer will eventually transform into 1.
+# The transformations are: divide by 2 if the number is even, multiply by 3 and add 1 if its odd.
+# You can see more about it here https://en.wikipedia.org/wiki/Collatz_conjecture
