We use that chars are just numbers, so we can easily convert them into the respective points by just subtracting `'A'` or `'X'`.
The rest is then just a few `if else`s.

<!-- including ChatGPT extra -->
All the characters (the Elf's items) occuring in (half) a line (backpack) are stored as bits in an unsigned long, duplicate characters can then be determined by bitwise and-ing these numbers.
```shell
# Find the item type that appears in both compartments of each rucksack. What is the sum of the priorities of those item types?

<!-- ChatGPT tought me Assembly -->
Today I wanted to use ChatGPT to solve the tasks using *gnu* **x86-64 assembly**, which I have never used before
(I did some small things in [6502-asssembly](https://github.com/MatthiasQuintern/6502), so it wasn't all new).

## The protagonist is stupid
The way the challenge is laid out is absolutely ridiculus; both tasks could be done in one-liners on a Linux machine *(which the device from the challenge probably is)*
in any POSIX shell,
*if* the user wasn't as stupid...
*if* the user wasn't as stupid as our protagonist...
That's why I wrote a bash script that actually creates the whole filesystem from the input-file.
It does so (by default) in `/tmp`. The sizes for the files are only allocated, so that `du` shows the filesize.
No actual write operations are taking place, which makes recreating the file structure pretty fast.
### I am stupid
### And so am I?
The problem is, that (even empty) directories have a size, which also increases with every file and subdirectory in it.
That's why I needed to calculate the sizes of the directories *without* the actual file sizes and subtract that from the output of `du`.
This new output can then be piped into an `awk` one-liner. In reality, this problem wouldn't exist since you would want the total size of a directory anyway.
