Palindromes

Palindromes are character sequences that read the same forward or backward (e.g. the strings "mom" or "radar" or “kayak” or “1234321”). You will write a program to determine whether a string is a character-unit palindrome.

Note: Programming Project should be done primarily on your own. However, it is appropriate to get some support from your professor, and even other students. Refer to the Syllabus for guidelines. Remember to use Piazza and post your partial code if you are stuck with a problem in your code.

Requirements

• Your program will take a string input from the user, to be evaluated with the program.
• An optional Boolean flag, will tell your program to be case-sensitive for all input strings. The default condition (i.e. if the flag is FALSE) is to ignore case-sensitivity. So, for example, "Mom" should evaluate as a palindrome if the flag is set to false, but should evaluate as NOT a palindrome if flag is set to TRUE.
• You must allow the program to be played repeatedly without ending the program between palindrome check.
• Typing 'y' or 'Y' or “Yes” causes program to run again. Anything else exits the program with output “Thanks for playing!”
• Follow formatting as demonstrated in the "Sample Output" below.
• 2 Bonus Points: Support strings with spaces such as "123 454 321"
• Make sure you have your name and Bronco ID in the header comment
  /*     Name: Jane-Doe
  *      Bronco ID: 12345678
  *      Sources of Help:  Jon Doe helped me with…………
  */

Example Output

Enter the string to evaluate for palindrome: Kayak
Kayak is a palindrome
Do you want to try again (Y or N)? Y

Enter the string to evaluate for palindrome: evil
evil is not a palindrome
Do you want to try again (Y or N)? N

Thanks for playing!

Bulls and Cows

Bulls and Cows is a guessing game where you try to guess an 'n' digit code. (Note: each number in the code must be distinct) When a number is guessed and a digit is in the correct location, then that is a bull. When a digit is in the number, but in the incorrect location, then that is a cow. So if a 3 digit code is 289, and the user guesses 829. Then that is "1 bull and 2 cows" because '9' is in the correct location and '2' and '8' are in the code but are currently in the wrong location. The guessing continues until the code is guessed in the correct order... "3 bulls"!

This website will give you a feel for the game. To emulate our version using 3 digits, click on "Options" and select any 0-9, 3 Codes. http://www.mathsisfun.com/games/bulls-and-cows.html

Note: Programming Project should be done primarily on your own. However, it is appropriate to get some support from your professor, and even other students. Refer to the Syllabus for guidelines. Remember to use Piazza and post your partial code if you are stuck with a problem in your code.

Requirements

• Use appropriate static methods to separate basic functionality of the implementation. For example: checkBulls(), checkCows() etc.
• Ask from the user to provide the option (3 digits, 4 digits or 5 digits code). Then use the provided generateRandomCode() method to generate a random code. The code must be stored in a String.
• Get guess from user as a String.
• If more digits than the number in the code, get number again. For example: the code is 3 digit (145) but user enters 5 digit guess (5687).
• If any digits are repeated, get number again.
  For example: If the user guess is 335, get the number again.
• If not enough digits, assume the missing digit to the left as zero. 
  For example: For a 3 digit code, 35 is the same as 035 where zero is the first digit. On the other hand, if user enters 5 for a 3 digit code, then you need to reject this entry because 005 is a repeating code.
• If the user enters string “quit” anytime during the play, the program should stop and display the code that the user was playing with output “Thanks for playing!”
• You must allow the program to be played repeatedly without ending the program after successful run (that is getting all the bulls).
• Typing 'y' causes program to run again. Anything else exits the program with output “Thanks for playing!”
• Follow formatting as demonstrated in the "Sample Output" below. Highlighted values are the user input.
• Make sure you have your name and Bronco ID in the header comment
