I've added some test cases, that will make it a bit more difficult to game this problem.
Cases 5 and 7 are identical, and I believe they are both wrong. 5 x 142857 = 714285. Isn't this a parasitic number? What am I missing?
Can the problem creator disqualify "solutions" that cheat? There should be a point penalty (-200) associated with cheating too.
