What is the mistake?

Hello @agarwalarjit.agarwal,

  1. You need not to check divisibility with every number smaller than num.
    Read point 3 given in the question.

  2. Your code will fail for point 2 mentioned in the question.

  3. stoi() won’t work for numbers greater than the range of int.

  4. Not accounting for the case mentioned in the question i.e.
    CB number once detected should not be sub-string or super-string of any other CB number.
    Solution:
    Use a separate array to mark the index of the detected CB numbers as visited.

  5. As you have to maximize the CB numbers, first check for all sub-strings of length 1 and then increase the size gradually.

For your mistakes refer to the following code:

Hope, this would help.
Give a like if you are satisfied.
