        def getHint(self, secret, guess):
            bulls = 0
            cows = 0
            cowcount = [0]*10
            for i in range(10):
                s = str(i)
                cowcount[i] = min(secret.count(s),guess.count(s))
            for i in range(len(secret)):
                if secret[i] == guess[i]:
                    bulls += 1
                    j = int(secret[i])
                    cowcount[j] -= 1
            for s in cowcount:
                cows += int(s)
            return str(bulls)+"A"+str(cows)+"B"
    

    Check for cows (the number of cows for a digit can't ever exceed secret, hence the min). Then check for bulls -- every bull is one less cow. Then calculate the total number of cows and return.
