App Profile: Bulls and Cows(3 digits)

I brought the Bulls and Cows(3~5 digits) rule as it is.
It's a game where you match three randomly set numbers!

*Rules*
You can enter 0 as well, and the numbers are not duplicated.
If both positions and numbers match, it's a bull. if the positions are wrong, and if only the numbers match, it's a cow.
Use the result given for each attempt to deduce the correct answer with minimal attempt!
