Clock Solitaire

Clock Solitaire is a simple card game.  The cards are dealt out (face down) in a circle, representing a clock, with a pile in each hour position and an extra pile in the center of the clock. The first card goes face down on one o'clock, the next on two, and so on clockwise from there, with each thirteenth card going to the center of the clock. This results in thirteen piles, with four cards face down in each pile.

The game then starts. The top card of the 'king' pile (the last card dealt) is exposed to become the current card. Each move thereafter consists of placing the current card face up beneath the pile corresponding to its value and exposing the top card of that pile as the new current card. Thus if the current card is an Ace it is placed under the 'one' pile and the top card of that pile becomes the current card. The game ends when the pile indicated by the current card has no face down cards in it. You win if the entire deck is played out, i.e. exposed.  The outcome is entirely up to chance, there is no skill other than placing cards in the correct piles.

Play online version.

You are to write a computer player that will determine the outcome of a Clock Solitaire game given a deck of shuffled cards, and return the results.

Input

The input data will be read from standard input and will contain one or more test cases.  Each test case contains a single line representing a shuffled deck of cards.  The first card is the top card on the deck.  The line consists of 52 2-letter card abbreviations, separated by one blank.  You may assume there are no duplicate cards, and all abbreviations are valid.

Output

For each test case, a single line of output is displayed on standard output.   The line contains two fields separated by a single blank.  The first field is a whole number representing the number of cards played during the game. The second field is a 2-letter card abbreviation of the last card played during the game.

Design Tips

Recommended classes in the design:
Card - Represents a single playing card.
Deck - Represents a deck from which cards are dealt.
Pile - A pile of cards at one position on the "clock".  (Use a stack to represent a pile of cards).
Table - The playing area where the game takes place. It contains the deck and the 13 piles. The game logic is handled here.
ClockSolitaire - ALL the input/output for the application occurs here. Reads the input deck and displays the results computed by the Table.

Note that in your computer simulation of the game, it isn't actually necessary to place the current card face up on the bottom of a pile.  After identifying the target pile, you can simply discard the current card.  To determine end of game, simply check if the target pile is empty.
 
Write JUnit tests for the classes you create or modify, except for ClockSolitaire.

The application class containing the main method should be named ClockSolitaire. 
Example unix command:
java ClockSolitaire < decks   will produce this output.
