This is the game to find 4 digits numbers with hints.
(This game is similar to hit and blow, numer0n, mastermind, 1a2b, bulls and cows, and code breaker.)
When you find a number in the same place, then you will be given a hint as 1Hit. When you find a number but in the different place, then you will be given a hint as 1 Blow.
For example, if the 4 numbers are 0123, and you guessed them as 9135, then you will get hint as 1H1B.
