Using the Die class, design and implement a game called Pig. In this game, the user competes against the computer. On each turn, the current player rolls a pair of dice and accumulates points. The goal is to reach $100$ points before your opponent does. If$,$ on any turn, the player rolls a $1,$ all points accumulated for that round are forfeited and control of the dice moves to the other player. If the player rolls two $1$s in one turn, the player loses all points accumulated thus far in the game and loses control of the dice. The player may voluntarily turn over the dice after each roll. Therefore, the player must decide to either roll again $($be a pig$)$ and risk losing points, or relinquish control of the dice, possibly allowing the other player to win. Implement the computer player such that it always relinquishes the dice after accumulating $20$ or more points in any given round.
