In your approach when you are checking a substring for CB number you are not checking for substrings that are inside that substring. For example if string is 4416618111011 then your code is computing CB numbers as 44166181 , 11 and 11. Which is having 2 reasons to get wrong :

  1. 11 is included two time. (and ques says that only 1 time a CB number should be included in final answer)
  2. in substring 44166181 there are 2 substring 41 and 661 which are also CB number so instead of that large string we should consider these two small sub string.

so what i need to do is form all the substrings and then from that collection check which all are feasible so that final ans is also max

yes … along with this you have to keep checking if that substring you have already included or not.
