The goal for this exercise is to practicing using the List<> class by implementing a solution to a small programming problem.
Note that in order to pass the NUnit tests, each value (each integer) should be printed out on its own line, with nothing else (not even blank spaces) on that line. The values should be printed out in order, so that the smallest value is printed first and the largest value is printed last.
