In the game there is every hand there is a hand that wins and another that loses, put in sequence, there will always be a winning hand in front and a losing hand in the back. In the return list, when the subtraction is zero, both have the same hand, so there is an impact, if the difference is just one unit, then p1 winner, and if the difference is 2 p2 winner, matching the indices defined in the list .
