Hello @Pranav_Chaudhary,

  1. The following function terminates for the string with length greater than 10
    int num=Integer.parseInt(number.substring(i, j+1));
    Also, the converted value can be long.

  2. You have start from all the substring of length 1 and then increment the size of substring as you have to find the maximum CB numbers.
    In your code, you are first checking for all the substrings starting from i=0, then all substrings from i=1 and so on. This way you would skip some CB numbers
    Solution:
    for(int i=1;i<=number.length();i++) {
    for(int j=0;j<=number.length()-i;j++) {
    //Check for substring(j,j+i)
    }
    }

  3. Create an array visited to keep track of indexes that have been used in the CB numbers that have been detected till now.

  4. A CB number is a prime number, if you observe it very carefully.

If you still face any issue, let me know.
I hope, this would help.
