i have made some possible changes in your code
now it work on most of cases

Modified Code

but this will not work on all testcases
because in this code we are not making all possible subsequences
so this will fail in some cases

Correct one

Logic:

  • Put loop on string that will give substring of every length.
  • create a function that will return true if the passed number is a CB number otherwise return false.
  • To put a check if the digit is already a part of the any other CB number, create an boolean array say, valid which store which digits till now has been a part of any other CB number.
  • Take a counter and increment if a CB number is found.
  • At the end print the count.
