"11"
"10"
答案是"1A0B"而不是"1A1B"
//下面那个是这道题的答案
ppublic class Solution {
    public String getHint(String secret, String guess) {
        char a='0';
        int bull=0;
        int cow=0;
        String result;
        int[]res1=new int[10];
        int[]res2=new int[10];
        boolean []res3=new boolean[10];
        for(int i=0;i<secret.length();i++){
            int b=(int)(secret.charAt(i)-a);
            int c=(int)(guess.charAt(i)-a);
            if(b==c)
            {bull++;
            
            }
            else{
            res1[b]++;
            res2[c]++;
            }
        }
        for(int i=0;i<10;i++){
            if(res1[i]!=0&&res2[i]!=0)
        
            cow+=Math.min(res1[i],res2[i]);//Here it should not be just cow++; since for example 2211 nad 1122;the result is 0A2B.
            So you need add the minimum value of these two values
            
        }
        result=bull+"A"+cow+"B";
        return result;
    }
}
