4. Edit this C# Rock Paper Scissors game below (algorithm & code) to validate the user's input. When the user enters something other than Rock, Paper or Scissors he/she/they should be forced to reenter a choice. Also make sure curly brackets are properly placed if they are not already. ==============================================================================================

Algorithm: Display instructions Get uChoice Get cChoice (random number generator 1-4) if cChoice == ROCK (1) message = the computer chose ROCK else if cChoice == PAPER (2) message = the computer chose PAPER else cChoice == SCISSORS (3) message = the computer chose SCISSORS end if if uChoice == PAPER and cChoice == ROCK || uChoice == SCISSORS and cChoice == PAPER || uChoice == ROCK and cChoice == SCISSORS message = You win! else if uChoice == ROCK and cChoice == ROCK || uChoice == SCISSORS and cChoice == SCISSORS || uChoice == PAPER and cChoice == PAPER message = Tie! else message = You lose! end if Display message
