Maybe someone find inspiration in my code. After almost seven hours non-stop working (not counting WC visits, and coffe/pizza break) I did this Frankenstain. I start this task yesterday and I tried did it with Pattern and Matcher help. It's not work, and I ending on help section. I find beauty code from Evgen but I don't understand fully regex with (?=) questionmark, I could copy this and do the rest, but somewhere else I have read comment's that it's possible do this without it, use knowledge whose we have. It's unbelievable, I was in trance reading it, I couldn't do this one more time from scrach. I know that posting complete solutions is not allowed but I need more experienced eyes looking for my algorithm and tell me what I can do to simplify it! Because I write it for success, and I know my solutions is too long, and maybe not so neat and optimal.
