 This is related to the Collatz Conjecture. What's weird is not mentioning it.

I wouldn't have known it was a famous math conjecture, but no doubt the author of the problem did.

                 len = strlen(result);
                 sprintf(result + len, "%d ", n);

 And what's odd here is collating the results in a string (especially when the possible number of steps is unknown). Why not just print it straight to the console?

My initial submission used straight to console.  It was rejected for untold reasons, so I tried a variety of changes, including collating.
I went back to printing to console, and along with the other fixes the code was finally accepted.
