Binary Casino has established a new department to attract families with children. One of its
first tasks is to design a game for children which will be not so difficult to play. The result of a
week of hard work is a game called Rullete.
Each player gets a hand of 5 cards. Cards in the hand are ordered as first, second, . . ., fifth.
Each card is described by a rank and a suit. Card's rank can be one of 2, 3, ..., 10, J, Q, K, A
and its suit can be one of D, H, C, or S (Diamonds, Hearts, Clubs, or Spades). Cards 210 have
scores equal to their rank and cards J, Q, K, and A all have a score of 10. Initially, a player's
hand has a value given by the sum of scores of the cards in his hand. The initial hand value is
then changed according to the rules of the game. To make croupier's life easier, your task is to
calculate the final value of you hand of cards after all of the following fourteen rules are applied
in the given order:
1. If you have at least 4 cards in your hand then add 1 to the value. Also add to the value
the product of the number of J's in your hand and the score of the first card in your hand.
2. If you have at least 2 cards of the same suit in your hand then multiply the value by 2.
3. If you have at least one card of each suit in your hand then multiply the value by 2.
4. If the count of black (Clubs and Spades) and the count of red (Hearts and Diamonds)
cards in your hand differ then add the absolute value of the difference of the counts to the
value.
5. If the value is currently even then add all positive integer divisors of the value (including
1 and the value itself ) to the value.
6. If there are exactly 4 cards of rank 7 in your hand then subtract 112 from the value.
7. If the value is currently non-negative then add the score of the lowest score card in your
hand to the value.
8. If the value is currently negative then multiply the value by -1.
9. If there are at least 3 cards of Diamond suit in your hand then add 1 to the value and
then simultaneously swap ranks of all 6's to 9's, all 9's to 6's, all 2's to 5's, and all 5's to
2's in your hand.
10. If there is a straight in your hand then add five times the number of A's in your hand to
the value.
11. If the value was modified by more than 8 rules so far then add the number of 1's bits in
the binary representation of the value to the value.
12. If there is at least one card of rank 2 in your hand then apply once again the last rule
which changed the value (after that continue with rule 13).
13. If there is at least one card of rank 2 in your hand then add the product of all distinct
superfactors of the value to the value. A superfactor is a prime raised to the highest integer
power so that it divides the value evenly.
14. If the value is 674 you win!
A straight is a set of any 5 consecutive cards in the following order: 2, 3, 4, 5, 6, 7, 8, 9, 10, J,
Q, K, A.
