You should thoroughly test all your Ruby scripts to make surethey are running as expected. With the Number Guessing game, thatmeans playing the game repeatedly. To make this easier on you, adda hidden “cheat” to the game that allows you to display the game’snumber. To implement this change, modify the game so that, inaddition to accepting a reply of y or n when prompting the playerfor permission to begin the game, it accepts a reply of c (forcheat). Next, modify the Game class’s play_game method so that itdisplays the game’s number when it’s run in cheat mode. ______________________________________________________________ #————————————————————————– # Description: This Ruby script is a number guessing game thatchallenges

# the player to guess a randomly generated number in 10
