In the game Rock paper Scissors, two players simultaneously choose one of three options: rock, paper, or scissors. If both players choose the same option, then the result is a tie. However, if they choose differently, the winner is determined as follows: Rock beats scissors, because a rock can break a pair of scissors. Scissors beats paper, because scissors can cut paper. Paper beats rock, because a piece of paper can cover a rock. Create a game in which the computer randomly chooses rock, paper, or scissors. Let the user enter a character, r, p, or s, each representing one of the three choices. Then, determine the winner. Save the application as RockPaperScissors.cs.
