Advent of Coda

Do fun coding challenges during the holidays!
Eric Koleda
The
Advent of Code
⁠
is a Christmas-themed, daily coding challenge that has been run each year since 2015. It’s a fun way to learn or sharpen your coding skills and have some fun during the holiday season.
You can complete the challenges using any programming language and environment you like, so why not a Coda Pack? This doc has everything you need to bootstrap your Pack and organize your solutions.
To get started,
Copy this doc
⁠
⁠

1️⃣ Pack code

When you copy the doc you’ll get a warning that the Advent of Code Pack is no longer available.

⁠
That’s expected, since you’ll need to create your own Pack with your solutions to the challenge. You can go ahead and remove it from the doc.
Use the code below to create your Pack. It provides the basic setup you’ll need to work with files and compute solutions.

2️⃣ Table setup

3️⃣ Daily Challenge

Every day, for each part of the daily challenge:
Add a new function to the Pack. For example, function Day1A(lines) { ... }
Include the function in the Solutions constant.
Rebuild the Pack.
Add a row to the table below, entering the name of the function and uploading the input file.
Click the Compute button to run the function and get the output.
Enter the output into the Advent of Code website and see if you got it right!
Each participant is given a unique file for each challenge, so make sure to delete the example files for the Day 1 challenges in the table below.
