Two-Player Pig

Pig is a folk jeopardy dice game with simple rules: Two players race to reach 100 points. Each turn, a player repeatedly rolls a die until either a 1 ("pig") is rolled or the player holds and scores the sum of the rolls (i.e. the turn total). At any time during a player's turn, the player is faced with two decisions:

roll - If the player rolls a
- 1: the player scores nothing and it becomes the opponent's turn.
- 2 - 6: the number is added to the player's turn total and the player's turn continues.
hold - The turn total is added to the player's score and it becomes the opponent's turn.

Problem: Simulate a single solitaire game of Pig where a player rolls until a 1 ("pig") is rolled, or the turn total is greater than or equal to 20, or the score plus the turn total is greater than or equal to 100.

Note: Be sure to "factor out common code". There is no reason to have two separate, nearly identical sections of code for each player's turn.

Input Format: (no input)

Output Format:

Before each turn, print a line with "Player 1 score: " and player 1's score. Print another line with "Player 2 score: " and player 2's score. Finally, print a line with "It is player #'s turn.", where "#" is replaced by the current player number. Play starts with player 1 and then alternates.
For each roll, print a line with "Roll: " and the random die roll value (1-6).
After a "pig" roll of 1, or a "hold", print a line with "Turn total: " followed by the turn total. In the case of a "pig", this turn total is 0. Then, print a line with "New score: " followed by the new score for the current player.
