    The 3n+1 problem/ Collatz Conjecture. Take a positive integer n, if its odd do 3n+1, otherwise in case of even divide it by 2. Perform this repeatedly and verify the number of sequence always reaches to 4->2->1

    That code is straightforward to write (but you have to watch for
    overflow). It is also a question if (3*n+1)/2 should be called
    a single step.

    Or are you asking us to write it for you?
