Tri-du
By Ricardo Anido, Universidade Estadual de Campinas 
Brazil
Timelimit: 1
Tri-du is a card game inspired in the popular game of Truco. The game uses a normal deck of 52 cards, with 13 cards of each suit, but suits are ignored. What is used is the value of the cards, considered as integers between 1 to 13.
In the game, each player gets three cards. The rules are simple:
- A Three of a Kind (three cards of the same value) wins over a Pair (two cards of the same value).
- A Three of a Kind formed by cards of a larger value wins over a Three of a Kind formed by cards of a smaller value.
- A Pair formed by cards of a larger value wins over a Pair formed by cards of a smaller value.
Note that the game may not have a winner in many situations; in those cases, the cards are returned to the deck, which is re-shuffled and a new game starts.
A player received already two of the three cards, and knows their values. Your task is to write a program to determine the value of the third card that maximizes the probability of that player winning the game.
Input
Output
Your program must produce a single line, containing exactly one integer, representing the value of the card that maximizes the probability of the player winning the game.
