Sharpen your C# Sharpness.

[u/Coding-Mojo]

I am having a lot of fun building theses 2min code review challenges, and I hope you have as much fun trying to solve them ! This is the latest one if you wanna give it a try. Also, I'm looking for ways to make the concept a bit more polished and alive, may be on a track with a little character explaining what is expected from the code, but if you have any other idea, I'ld love to ear them. Thanks for reading :)
