-# Contributor Covenant Code of Conduct
-
-## Our Pledge
-
-We as members, contributors, and leaders pledge to make participation in our
-community a harassment-free experience for everyone, regardless of age, body
-size, visible or invisible disability, ethnicity, sex characteristics, gender
-identity and expression, level of experience, education, socio-economic status,
-nationality, personal appearance, race, religion, or sexual identity
-and orientation.
-
-We pledge to act and interact in ways that contribute to an open, welcoming,
-diverse, inclusive, and healthy community.
-
-## Our Standards
-
-Examples of behavior that contributes to a positive environment for our
-community include:
-
- Demonstrating empathy and kindness toward other people
- Being respectful of differing opinions, viewpoints, and experiences
- Giving and gracefully accepting constructive feedback
- Accepting responsibility and apologizing to those affected by our mistakes,
-  and learning from the experience
- Focusing on what is best not just for us as individuals, but for the
-  overall community
-
-Examples of unacceptable behavior include:
-
- The use of sexualized language or imagery, and sexual attention or
-  advances of any kind
- Trolling, insulting or derogatory comments, and personal or political attacks
- Public or private harassment
- Publishing others' private information, such as a physical or email
-  address, without their explicit permission
- Other conduct which could reasonably be considered inappropriate in a
-  professional setting
-
-## Enforcement Responsibilities
-
-Community leaders are responsible for clarifying and enforcing our standards of
-acceptable behavior and will take appropriate and fair corrective action in
-response to any behavior that they deem inappropriate, threatening, offensive,
-or harmful.
-
-Community leaders have the right and responsibility to remove, edit, or reject
-comments, commits, code, wiki edits, issues, and other contributions that are
-not aligned to this Code of Conduct, and will communicate reasons for moderation
-decisions when appropriate.
-
-## Scope
-
-This Code of Conduct applies within all community spaces, and also applies when
-an individual is officially representing the community in public spaces.
-Examples of representing our community include using an official e-mail address,
-posting via an official social media account, or acting as an appointed
-representative at an online or offline event.
-
-## Enforcement
-
-Instances of abusive, harassing, or otherwise unacceptable behavior may be
-reported to the community leaders responsible for enforcement at
-<contact@theoludwig.fr>.
-All complaints will be reviewed and investigated promptly and fairly.
-
-All community leaders are obligated to respect the privacy and security of the
-reporter of any incident.
-
-## Enforcement Guidelines
-
-Community leaders will follow these Community Impact Guidelines in determining
-the consequences for any action they deem in violation of this Code of Conduct:
-
-### 1. Correction
-
-**Community Impact**: Use of inappropriate language or other behavior deemed
-unprofessional or unwelcome in the community.
-
-**Consequence**: A private, written warning from community leaders, providing
-clarity around the nature of the violation and an explanation of why the
-behavior was inappropriate. A public apology may be requested.
-
-### 2. Warning
-
-**Community Impact**: A violation through a single incident or series
-of actions.
-
-**Consequence**: A warning with consequences for continued behavior. No
-interaction with the people involved, including unsolicited interaction with
-those enforcing the Code of Conduct, for a specified period of time. This
-includes avoiding interactions in community spaces as well as external channels
-like social media. Violating these terms may lead to a temporary or
-permanent ban.
-
-### 3. Temporary Ban
-
-**Community Impact**: A serious violation of community standards, including
-sustained inappropriate behavior.
-
-**Consequence**: A temporary ban from any sort of interaction or public
-communication with the community for a specified period of time. No public or
-private interaction with the people involved, including unsolicited interaction
-with those enforcing the Code of Conduct, is allowed during this period.
-Violating these terms may lead to a permanent ban.
-
-### 4. Permanent Ban
-
-**Community Impact**: Demonstrating a pattern of violation of community
-standards, including sustained inappropriate behavior, harassment of an
-individual, or aggression toward or disparagement of classes of individuals.
-
-**Consequence**: A permanent ban from any sort of public interaction within
-the community.

+# - Day 1 of 2024: Historian Hysteria -
+
+Source: <https://adventofcode.com/2024/day/1>
+
+## Instructions - Part 1
+
+The **Chief Historian** is always present for the big Christmas sleigh launch, but nobody has seen him in months! Last anyone heard, he was visiting locations that are historically significant to the North Pole; a group of Senior Historians has asked you to accompany them as they check the places they think he was most likely to visit.
+
+As each location is checked, they will mark it on their list with a star. They figure the Chief Historian **must** be in one of the first fifty places they'll look, so in order to save Christmas, you need to help them get **fifty stars** on their list before Santa takes off on December 25th.
+
+Collect stars by solving puzzles. Two puzzles will be made available on each day in the Advent calendar; the second puzzle is unlocked when you complete the first. Each puzzle grants **one star**. Good luck!
+
+You haven't even left yet and the group of Elvish Senior Historians has already hit a problem: their list of locations to check is currently empty. Eventually, someone decides that the best place to check first would be the Chief Historian's office.
+
+Upon pouring into the office, everyone confirms that the Chief Historian is indeed nowhere to be found. Instead, the Elves discover an assortment of notes and lists of historically significant locations! This seems to be the planning the Chief Historian was doing before he left. Perhaps these notes can be used to determine which locations to search?
+
+Throughout the Chief's office, the historically significant locations are listed not by name but by a unique number called the location ID. To make sure they don't miss anything, The Historians split into two groups, each searching the office and trying to create their own complete list of location IDs.
+
+There's just one problem: by holding the two lists up side by side (your puzzle input), it quickly becomes clear that the lists aren't very similar. Maybe you can help The Historians reconcile their lists?
+
+For example:
+
+```txt
+3 4
+4 3
+2 5
+1 3
+3 9
+3 3
+```
+
+Maybe the lists are only off by a small amount! To find out, pair up the numbers and measure how far apart they are. Pair up the **smallest number in the left list** with the **smallest number in the right list**, then the second-smallest left number with the second-smallest right number, and so on.
+
+Within each pair, figure out **how far apart** the two numbers are; you'll need to **add up all of those distances**. For example, if you pair up a `3` from the left list with a `7` from the right list, the distance apart is `4`; if you pair up a `9` with a `3`, the distance apart is `6`.
+
+In the example list above, the pairs and distances would be as follows:
+
+- The smallest number in the left list is `1`, and the smallest number in the right list is `3`. The distance between them is `2`.
+- The second-smallest number in the left list is `2`, and the second-smallest number in the right list is another `3`. The distance between them is `1`.
+- The third-smallest number in both lists is `3`, so the distance between them is `0`.
+- The next numbers to pair up are `3` and `4`, a distance of `1`.
+- The fifth-smallest numbers in each list are `3` and `5`, a distance of `2`.
+- Finally, the largest number in the left list is `4`, while the largest number in the right list is `9`; these are a distance `5` apart.
+
+To find the **total distance** between the left list and the right list, add up the distances between all of the pairs you found. In the example above, this is `2 + 1 + 0 + 1 + 2 + 5`, a total distance of `11`!
+
+Your actual left and right lists contain many location IDs. **What is the total distance between your lists?**
+
+## Instructions - Part 2
+
+Your analysis only confirmed what everyone feared: the two lists of location IDs are indeed very different.
+
+Or are they?
+
+The Historians can't agree on which group made the mistakes or how to read most of the Chief's handwriting, but in the commotion you notice an interesting detail: a lot of location IDs appear in both lists! Maybe the other numbers aren't location IDs at all but rather misinterpreted handwriting.
+
+This time, you'll need to figure out exactly how often each number from the left list appears in the right list. Calculate a total similarity score by adding up each number in the left list after multiplying it by the number of times that number appears in the right list.
+
+Here are the same example lists again:
+
+```txt
+3   4
+4   3
+2   5
+1   3
+3   9
+3   3
+```
+
+For these example lists, here is the process of finding the similarity score:
+
+- The first number in the left list is `3`. It appears in the right list three times, so the similarity score increases by `3 * 3 = 9`.
+- The second number in the left list is 4. It appears in the right list once, so the similarity score increases by `4 * 1 = 4`.
+- The third number in the left list is `2`. It does not appear in the right list, so the similarity score does not increase (`2 * 0 = 0`).
+- The fourth number, `1`, also does not appear in the right list.
+- The fifth number, `3`, appears in the right list three times; the similarity score increases by `9`.
+- The last number, `3`, appears in the right list three times; the similarity score again increases by `9`.
+
+So, for these example lists, the similarity score at the end of this process is `31` (`9 + 4 + 0 + 0 + 9 + 9`).
+
+Once again consider your left and right lists. **What is their similarity score?**
