Write a program that plays the game Bulls And Cows. A sample run might look like this: Welcome to Bulls and Cows. You have 12 guesses to discover the random four digit number that has been chosen. All digits are unique. A bull means that you have the correct digit in the correct place, a cow that you have the correct digit in the wrong place. Enter a guess: 3703 Digits must be unique Enter a guess: 37 There must be four digits Enter a guess 31298 There must be four digits Enter a guess: 3701 1 bulls 2 cows Enter a guess: 3702 1 bulls 1 cows Enter a guess: 3714 2 bulls 2 cows Enter a guess: 3174 1 bulls 3 cows Enter a guess: 1734 0 bulls 4 cows Enter a guess: 3741 1 bulls 3 cows Enter a guess: 3417 4 bulls 0 cows took you 7 guesses! You can design the game any way you want, but should use methods to perform the various tasks, rather than putting all the code in the main method, so that your program is modular. Print instructions for the user at the start of the program (which you might want to store in a separate method). If users guess the number, indicate how many turns it took them, if they don't tell them what the number was
