Write a program that plays the popular scissor-rock-paper game. (A scissor can cut a paper, a rock can knock a scissor, and a paper can wrap a rock.) The program randomly generates a number 0, 1, or 2 representing scissor, rock, and paper. The program prompts the user to enter a number 0, 1, or 2 and displays a message indicating whether the user or the computer wins, loses, or draws. Here are sample runs:

Enter your selection: scissor (0), rock (1), paper (2): 1 <enter>

The computer is scissor. You are rock. You won

Enter your selection: scissor (0), rock (1), paper (2): 2 <enter>

The computer is paper. You are paper too. It is a draw

Now revise the program to let the user continuously play until either the user or the computer wins more than two times than its opponent.

!!!!!!!!!!PLEASE ADD IN THE OPTION FOR THE USER TO PLAY CONTINUEOSLY UNTIL SOMEONE WINS MORE THAN TWO TIMES THAN THEIR OPPONENT, THIS IS THE MOST IMPORTANT STEP.!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
