Why??? It is a jok?? I sure you intentionally wrote this code so long :)

I think it would be more stylish if you try to utilise CPP standard libraries and exert new methods in your codes.

I like your approach, but I think it would be better to try to apply CPP standard libraries in your code. This Kata is easy and straight forward and people can understand it easily, while you sometimes have to write a long code or sctrip to do sth, then it might be problematic for other.

There will remain a big query in my mind forever about writing the asnwers!
Should we write them based on our approaches or using modules!!?
