Bulls and Cows solver

It usually takes 4-5 guesses to find the 4-digit number.

I'm too lazy to write fancy interface for such a simple program :)

HEY! Please don't use this spoiler at our own site!
Thanks a lot! :)

PS: I am receiving many requests from our visitors to add some more features to the program like:
Can/Cannot start from zero, Can/Cannot have the same digits, Predefined initial guess, etc...
I will write a new version as soon as I have some free time for that (no idea when).
