Full House

/* In most Poker games, the "full house" hand is defined as three cards of the same face
 * + two cards of the same face, other than the first, regardless of the card's suits.
 * The cards faces are "2", "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K" and "A".
 * The card suits are "♣", "♦", "♥" and "♠".
 * Write a program to generate and print all full houses and print their number. */
