Error in test policy

I am trying to upload my last solution of programming challenges but the policiy test fails and I don’t understand the error. Maybe someone can tell me what it means and how can I fix it?


The test_policy try to calculate the deviation of unique solution, and you will try to make that your deviation try to become 0, for that reason you must make a hack or vbd challenge, because if you upload another for code your deviation become 3, try to solve 2 of hack, 2 of vbd and you an upload again for code.
