I had the same problem on Python language, I had to modify my regex to avoid \n at the end. But I saw other solutions published by other people on Python with a regular expression that not includes it and have failed for me on the first attemps. Its a bit confusing to see solutions that was not valid or doesn't works actually. I'm figuring that its posible that the kata tests cases was changed after the solution was published, may be?

Test your solution with ExpressionsMatter(1, 1, 1) == 3 and you'll see.

I'm familar with operators for the most part, just have not implemented them like in your solution. Still need some work on the Null-coalescing operator ('??') and the conditional operator ('?:') though.

I know that boolean values are either true or false.
Though I had it mixed up in my orignal comment, but the default value of a boolean is false.

So, I was a tad confused when trying to explain out your solution to myself.

no, boolean values are EITHER true OR false. you should also study C# operators (of all kinds)

This works, because bools are "automatically" set to 'true' right?
So, it's reading employed == true and vaction not == true, then outcome is true (set alarm)?

Can anyone give quick explantion to this one?

Thanks!

It's part of the string: "1234\n"

I misspoke,

I meant that I included the use of Beginning and Ending *String identifiers.

So, is this new line a sperate string?

Not a kata issue, it's a problem with your code, there is a new line there.

C# Completions 2425

My solution includes the use of Beginning and Ending Line identifiers.

That's not enough.

Getting:

Test Failed
Wrong output for "1234

"

Expected: False

But was: True

Except my solution works in VS and other Regex Testers when tested against the same Test Case...
My solution includes the use of Beginning and Ending Line identifiers.
