Little Caesar likes card games. Everytime he comes to Zagreb, he plays blackjack, the famous card game, with his friends.

In this game, the player draws cards while the sum of the cards in his hand is less than or equal to or until he says `DOSTA`

(Croatian for "STOP").

At the beginning of the game, there are cards in the deck, thirteen ranks of each of the four suits. The card ranks are two, three, …, ten, Jack, Queen, King and Ace. The card values are the following: the cards with numbers on them are worth that number (e.g., "nine" is ), the cards with pictures (Jack, Queen, and King) are worth , whereas the Ace is worth .

Caesar has found himself in an interesting situation. During the game, he already drew cards whose sum is less than or equal to and is now having second thoughts about drawing one more card or not. Let's assume is the difference from the sum of the cards so far to . Everybody knows that you don't draw a card if the number of the remaining cards in the deck whose value is greater than is greater than or equal to the number of the remaining cards in the deck whose value is less than or equal to .

Since Caesar is having a difficult time calculating whether he needs to draw another card or not, he's asking you to do it for him.
