Advent of Code - Day 5

If only we hadn’t switched to the new inventory management system right before Christmas!

Part 1

In this part we’re asked to check if an ID is within a range and count the number where this is true. This was not very difficult. Similar to other challenges read in the lines, split them along the “,” delimiter, and use these ranges to confirm if the later list is fresh or not.

Got a comment about this possible syntax so I used this instead of two expressions with and inbetween.

 if fresh[0] <= id <= fresh[1]:

This is a pretty useful simplification where I think some other examples I’ve seen can be a bit obfiscating and confusing.

Part 2

The second part is a count of all ingredient IDs that are fresh. I spent a bunch of time overcomplicating this problem. Eventually I threw it all out and started blank and eventually got there. The solution isn’t even interesting to share here. Just a reminder for myself to not complicate things.
