OP solved it, closing

The last number is 99, so increment 99 by 1, which is 100.

Would you please give example entrie that are not in the test?

Could there be entries other the examples you have give.
If there are, please add one or two more examples,
because my code can successfully pass the entries you have give plus the one on the test.

What should be the RIGHT answer for the below entry

'abcd23abdcbd99'

according to this Kata?

Help Please!!!

What should be the RIGHT answer for this entry 'abcd23abdcbd99' and '123' according to this Kata?

Hey,
My code works fine for the Test examples given there, and it can pass the test. But I pressed the attempt button, it fails in some of
the cases.
Would you please give any intput that are not in the exaples and that are signifiacantly different from the given ones.
Want some examples that are not in the test case, but could appper in real test.

Thank you, natan(2 kyu).
I followed your advice and solved it.

Thank for usingful reply with hints.
One ohter thing I forgot to mention that I am trying to solve this kata in Python.
Next time I will go with your suggestion.

You can solve it using any of those.
What you should probably be doing though is to think about how you would solve it yourself as a human being. Then write your program to do the same actions.

Hello,
I am in need of some hints.
I tried to solve this kata by bilding dictionaries, but failed.
so, my question is there a way to solve this using only lists or sets, and not using dictionaries at all.
Thanks for reading. Any hints will be welcomed.
