Bulls and Cows(3 digits) app analytics for September 18

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!
