Also known as "Gauss' Trick"

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.

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!

I misspoke,

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

So, is this new line a sperate string?

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.
