C# is for the bigger and bolder.

goto?!? Wow, haven't seen a goto statement in decades...didn't even know you could use them in C#.

In the description.

If you absolutely need more than what is in there to solve the kata, please raise an Issue.
If you would like to have more to solve locally or something, please accept you're going to have to solve on CW ( or get creative filling in what's missing ).

Where do i find the complete class TreeNode for C# to test my function?

Is for example "abcd" and "dcba" same? Or is it 4 to change?

I dont understand how each Number Attribute has to have a getter which returns a double (because the result has to be a double),
but at the same time it should return an FluentCalculator, so that the next operator can call it.
I could solve it if every Test had a Result() function at the end... but i have no clue.

Yeah i know I will come back to it but right now it makes for me no sense that the tests give back wrong feedback so I cant adjust my code.

I worked on it from beta to release more than two months, and you want to get through it in just two days?

Im working on this now for 2,5 days and I im so stuck, so I will probably come back when im better. I looked at the other solutions and was just shocked hahaha

I changed one thing, that takes matches as a parameter but doesnt change matches itself, but somehow the tests dont work now.

Yeah right know im not focused on the 16 steps, more that it simply works in 100 steps. But for instance the Code was 2478 and 2222 gave back 0 Matches.

Don't give up:) You can modify and use sample tests for debugging
