# haunted_wasteland

This folder contains a Logtalk solution for the Advent of Code 2023 Day 8
problem:

https://adventofcode.com/2023/day/8

The `test_files` directory contain sample inputs for part 1 of the problem
copied from the problem description. For copyright reasons, the part 2 files
cannot be distributed here and **must** be downloaded from the Advent of Code
2023 website.

Print Logtalk, Prolog backend, and kernel versions (if running as a notebook):

```logtalk
%versions
```

Start by loading the example:

```logtalk
logtalk_load(haunted_wasteland(loader)).
```

<!--
true.
-->

Compute the number of steps for the `test_files/sample_1` file (part 1):

```logtalk
object_property(haunted_wasteland, file(_, Directory)),
atom_concat(Directory, 'test_files/sample_1', File),
haunted_wasteland::steps_1(File, Steps).
```

<!--
Steps = 2.
-->

Compute the number of steps for the `test_files/sample_2` file (part 1):

```logtalk
object_property(haunted_wasteland, file(_, Directory)),
atom_concat(Directory, 'test_files/sample_2', File),
haunted_wasteland::steps_1(File, Steps).
```

<!--
Steps = 6.
-->

Compute the number of steps for the `test_files/input` file (part 2):

```logtalk
object_property(haunted_wasteland, file(_, Directory)),
atom_concat(Directory, 'test_files/input', File),
haunted_wasteland::steps_1(File, Steps).
```

<!--
Steps = 21409.
-->

Compute the total number of steps for the `test_files/input` file (part 2):

```logtalk
object_property(haunted_wasteland, file(_, Directory)),
atom_concat(Directory, 'test_files/input', File),
haunted_wasteland::steps_2(File, Steps).
```

<!--
Steps = 21165830176709.
