They're trying to lull you into complacency, Esther. DON'T FALL FOR IT!! Intcode could be just around the corner!!! ***DOOOOOOM***

 

Totally agree, feel like this one was simple (thank you, Multi-Row Formula), but I am still impressed/annoyed at the overall AoC leaderboard folks who apparently solved both puzzles in less than 2 minutes.

 

Like, it takes me two minutes to remember what year this is.

Nice gentle start this year

A neat trick for this one is if you're comparing ABC with BCD then you only need to compare A with D, and multi-row lookup 3 rows back will do you fine in one tool.

As usual day 1 is fine, it's always interesting (like with weekly challenges) seeing others solutions and seeing tool golf like with @Balders solution.

Agree... Day 1 is always easy. But don't worry, it WILL get harder.
