The person who gets the card first gets four, so there are 50 left. No matter how many cards the second person takes, the person who takes the card first only needs to ensure that the sum of the number of cards taken by the second person is five, that is, if the second person takes a card, then the person who takes the card first takes four cards; If the second person takes 2 cards, then the person who takes the card first takes 3 cards; By analogy, there must be five cards left in the end, so no matter the last few cards of the second person, the person who gets the card first will definitely get the last card.
