Rules
-------
The objective is to correctly guess the 4 digits 
number generated by the computer.

A bull means that you have guessed a digit and it is in the correct position.

A cow means that you have guessed a digit but it is in the wrong position.

For example, if the  is 5682 and your guess is 5870, 
then you have scored 1 COW and 1 BULL. 
The 1 BULL is for the digit "5" which, as you guessed, is in the first position.
The 1 COW is for the digit  "8" which is in a different position.

You can keep guessing till you find the correct number.
