Gratz Elk, I included in my zero code to try to manipulate you but I fall into the very same trap set by you. The code is either or , where is either or in the 1st case and either or in the 2nd one. So Sub is right; there is a 25% chance to solve the code... I will take my wild guess and I say that I doubt theElk included an element that appears 2 times in his code, so I will normally had to discard the possibility. Actually, since I have no other way to eliminate any more results, I am going to bet that Elk is evil enough to include 2 times in his code and once in his zero-attempt one because he has proven that he possess that amount of evil cunningness in the past. So, I will give all my faith in the following result...
