Given that altogether four positions meet the condition leaving this question open will result in a multitude of different outputs that are solutions of the task. In my opinion a programming quiz should use a well-posed problem so that the different programs can be compared directly. Especially if the problem can be solved by constructing a clever mathematical formula which my intuition suggest to be the case with the number spiral problem (I did not yet try to verify this).
