We encountered a drunk human which had this binary file in his possession. We do not really understand the calculation which the algorithm does. And that is the problem. Can you imagine the disgrace we have to suffer, when we robots, based on logic, can not understand an algorithm? Somehow it seems that the algorithm imitates their masters and behaves …. drunk! So let us not suffer this disgrace and reverse the algorithm and get the correct solution.
