## Instructions - Part 1
|
||||||
|
|
||||||
|
You're still riding a camel across Desert Island when you spot a sandstorm quickly approaching. When you turn to warn the Elf, she disappears before your eyes! To be fair, she had just finished warning you about **ghosts** a few minutes ago.
|
||||||
|
|
||||||
|
One of the camel's pouches is labeled "maps" - sure enough, it's full of documents (your puzzle input) about how to navigate the desert. At least, you're pretty sure that's what they are; one of the documents contains a list of left/right instructions, and the rest of the documents seem to describe some kind of **network** of labeled nodes.
|
||||||
|
|
||||||
|
It seems like you're meant to use the **left/right** instructions **to navigate the network**. Perhaps if you have the camel follow the same instructions, you can escape the haunted wasteland!
|
||||||
|
|
||||||
|
After examining the maps for a bit, two nodes stick out: `AAA` and `ZZZ`. You feel like `AAA` is where you are now, and you have to follow the left/right instructions until you reach `ZZZ`.
|
||||||
|
|
||||||
|
This format defines each node of the network individually. For example:
|
||||||
|
|
||||||
|
```txt
|
||||||
|
RL
|
||||||
|
|
||||||
|
AAA = (BBB, CCC)
|
||||||
|
BBB = (DDD, EEE)
|
||||||
|
CCC = (ZZZ, GGG)
|
||||||
|
DDD = (DDD, DDD)
|
||||||
|
EEE = (EEE, EEE)
|
||||||
|
GGG = (GGG, GGG)
|
||||||
|
ZZZ = (ZZZ, ZZZ)
|
||||||
|
```
|
||||||
|
|
||||||
|
Starting with `AAA`, you need to **look up the next element** based on the next left/right instruction in your input. In this example, start with `AAA` and go **right** (`R`) by choosing the right element of `AAA`, **`CCC`**. Then, `L` means to choose the **left** element of `CCC`, **`ZZZ`**. By following the left/right instructions, you reach `ZZZ` in **`2`** steps.
|
||||||
|
|
||||||
|
Of course, you might not find `ZZZ` right away. If you run out of left/right instructions, repeat the whole sequence of instructions as necessary: `RL` really means `RLRLRLRLRLRLRLRL...` and so on. For example, here is a situation that takes **`6`** steps to reach `ZZZ`:
|
||||||
|
|
||||||
|
```txt
|
||||||
|
LLR
|
||||||
|
|
||||||
|
AAA = (BBB, BBB)
|
||||||
|
BBB = (AAA, ZZZ)
|
||||||
|
ZZZ = (ZZZ, ZZZ)
|
||||||
|
```
|
||||||
|
|
||||||
|
Starting at `AAA`, follow the left/right instructions. **How many steps are required to reach `ZZZ`?**
