Provide a correct Python 3 solution for this coding contest problem.
A sequence a=\\{a_1,a_2,a_3,......\\} is determined as follows:
* The first term s is given as input.
* Let f(n) be the following function: f(n) = n/2 if n is even, and f(n) = 3n+1 if n is odd.
* a_i = s when i = 1, and a_i = f(a_{i-1}) when i > 1... | instruction | 0 | 2,287 | 5 | 4,574 |
