 | 01  | [Problem](https://adventofcode.com/2025/day/1)  | [Solution](./cmd/01/) | Part 1 seemed straight forward enough. Part 2 completely stumped me. The trickiest part was not counting zero's twice when you ended and then started from there.                                                     |
 | 02  | [Problem](https://adventofcode.com/2025/day/2)  | [Solution](./cmd/02/) | Part 1 should have been super straight-forward, but some whitespace screwed up my parsing of the final range. I some how was able to stumble over a solution to part 2 rather blindly.                                |
 | 03  | [Problem](https://adventofcode.com/2025/day/3)  | [Solution](./cmd/03/) | Part 1 intuitively makes you think you only care about highest nums, but then you need to consider placement. I once again tripped over the solution using a stack. However chat morally supported me the whole time. |
