It's a lambda expression! Sort of like a simplified method. In this case, you can think of the => as a kind of return statement.

What does the => do?

Nice one

I have seen something like this, but you made it in the single line of code. Amazing

As I was submitting my boring solution that simulates the "fight" I was thinking it'd be easier and better to just throw some math at problem. This is that solution.

C#
Passes initial tests but fails when trying to submit with:

{"stdout":"","stderr":"/tmp/csharp116516-17-12tjut2/fixture.cs(81,13): warning CS0219: The variable `textCount' is assigned but its value is never used\n","wallTime":0}

I don't believe I have any access to textCount, can't submit.

Getting this as well.

System.Collections.Generic is the namespace for List and most of the other common, useful collection classes.

System.Collections has a couple collections that are from older versions of C# (I believe) and are generally not very useful.
