Problem 21. Return the 3n+1 sequence for n

A Collatz sequence is the sequence where, for a given number n, the next number in the sequence is either n/2 if the number is even or 3n+1 if the number is odd. The sequence always terminates with 1.

So if

 n = 13

then

 c = [13    40    20    10     5    16     8     4     2     1]
