# Day 3: Gear Ratios
|
||||
|
||||
## Part 1
|
||||
|
||||
You and the Elf eventually reach a gondola lift station; he says the gondola lift will take you up to the **water source**,
|
||||
but this is as far as he can bring you. You go inside.
|
||||
|
||||
It doesn't take long to find the gondolas, but there seems to be a problem: they're not moving.
|
||||
|
||||
"Aaah!"
|
||||
|
||||
You turn around to see a slightly-greasy Elf with a wrench and a look of surprise. "Sorry, I wasn't expecting anyone!
|
||||
The gondola lift isn't working right now; it'll still be a while before I can fix it." You offer to help.
|
||||
|
||||
The engineer explains that an engine part seems to be missing from the engine, but nobody can figure out which one.
|
||||
If you can **add up all the part numbers** in the engine schematic, it should be easy to work out which part is missing.
|
||||
|
||||
The engine schematic (your puzzle input) consists of a visual representation of the engine. There are lots of numbers
|
||||
and symbols you don't really understand, but apparently any number adjacent to a symbol, even diagonally, is a
|
||||
"part number" and should be included in your sum. (Periods (.) do not count as a symbol.)
|
||||
|
||||
Here is an example engine schematic:
|
||||
|
||||
```
|
||||
467..114..
|
||||
...*......
|
||||
..35..633.
|
||||
......#...
|
||||
617*......
|
||||
.....+.58.
|
||||
..592.....
|
||||
......755.
|
||||
...$.*....
|
||||
.664.598..
|
||||
```
|
||||
|
||||
In this schematic, two numbers are **not** part numbers because they are not adjacent to a symbol: `114` (top right) and
|
||||
`58` (middle right). Every other number is adjacent to a symbol and so **is** a part number; their sum is `**4361**`.
|
||||
|
||||
Of course, the actual engine schematic is much larger.
|
||||
**What is the sum of all of the part numbers in the engine schematic?**
