[Haskell-cafe] Programming Chalenges: The 3n+1 problem

[Felipe Almeida Lessa]

This is very similar to the Problem 14 on Project Euler [1].  Should
you really want a nice solution in Haskell, and noting that this is a
big spoiler, there are some on the wiki [2].  But I highly recommend
you to try coding your own solutions before looking at the site =).

Cheers!
