Day 4 is here! Our first puzzle launched on a weeknight. Hopefully, we're able to keep up this pace!

Today's challenge makes me feel very much like a secret agent as we observe elfy guards falling asleep on duty: figuring out who is sleeping, when, and how much.

I haven't even started this challenge yet (hoping to get to it this evening or maybe at lunch), but I wanted to get the post up for everybody else to share their solutions.

Good luck!
