what is the error in it

Hello @royprincejmp,

  1. There is a problem in the conversion of string to int i.e. k
    Try to print the following:
    k=s[i];
    cout<<k<<endl; //ADD these
    You will understand your mistake.

  2. If you would print num, then you would realise that your code is initially checking for all the subarrays/substrings that are starting from index i=0. And after detecting a CB number, it makes i=j. Correct?
    Like in the example mentioned in my previous reply, it detected two CB numbers though actually there were 4 CB numbers:
    Example:
    11
    44166181111
    Your Output:
    2
    Detected CB numbers:
    44166181
    11
    Actual:
    41
    61
    11
    11

Solution:

  1. Check for all the substrings starting from smallest size i.e. 1, then gradually increase the size.
  2. Also, use an array to mark the indexes that are used in the CB numbers that are already detected.

Correct your code and let me know if you don’t understand something.
