International Obfuscated Kotlin Contest

Do you have a coworker who writes the most incomprehensible Kotlin code you've ever seen? Have you inherited such an utter mess of a codebase that it deserves its very own Wikipedia article? Then this repository is for you!

The aim of this contest is to pass the tests for each challenge, by writing the most convoluted Kotlin programs possible.

An example

For example, consider this innocent Hello World program:

println("Hello World")

Wouldn't you have more job security if all your pull requests looked more like this?

val `_^`: Byte = 27
val `)`: Byte = (11.1 * 10).toByte()
val WAT = byteArrayOf(72, 101, 54 * 2, (`_^` * 4).toByte(),
    `)`, 44, 32, 87, `)`, 114, 27 * 4, 100, 33)
println(String(WAT))

Obviously, that is just an example. Real submissions should be much, much more incomprehensible.

Previous Challenges

Challenge 01: Hello World

Current Challenge

Fork the repository, read the current challenge, and pass the tests with your obfuscated code.

When you're happy with your solution, open a PR with a copy of the file, with your GitHub username as a suffix for the file, class, and method names. For example, n01HelloWorld would become n01HelloWorld_<username>.

Please document how your monstrosity works using KDoc. An example of a submission is shown here.

Judging

After around a month has passed, submissions will be closed, and the top entries will make it into the Hall of Infamy.

Points will be given for:

• Degree of incomprehensibility, measured in WTFs/min
• Abuse of language features specific to Kotlin, such as extension functions and operator overloads
• Originality and other clever hacks

After judging, the next challenge will then be opened for submissions. Stay tuned by watching the GitHub repository, as a new release will be used to notify everyone.

Improving the contest

Open an issue if you have a suggestion for a new challenge, or think the contest could be better by changing something.

It's early days and I'm open to ideas.
