Mars Exploration Solution
=========================

For the remaining two problems we will share with you a solution we
created that solves the problem, but you will be responsible for
following the steps.

If you want more practice on following all the steps, talk it over with
your fellow classmates, or your mentor!

Python3 Solution
----------------

.. code:: python

   string_mistakes = 0
   where_are_we = 1
   for i in range(len(s)):
       if where_are_we == 1 or where_are_we == 3:
           if s[i] != "S":
               string_mistakes += 1
       elif where_are_we == 2:
           if s[i] != "O":
               string_mistakes += 1
       if where_are_we == 3:
           where_are_we = 1
       else:
           where_are_we += 1
   print(string_mistakes)
