Prerequisites

• JDK 8 or newer (I use OpenJDK 11 in this example)
• Leiningen
• Maven
• Azure CLI
• A valid Azure subscription (you can try it for free)

public class WtfCreator {
    public static void main(String[] args) {
        var text = "Hello, world!\n";

        double[] x = new double[text.length() + 1];
        double[] y = new double[text.length() + 1];
        for(var i = 0; i < text.length(); i++) {
            x[i] = i;

How does my Clojure solution to the Day 3 problem from AOC 2017 work?

Link to the code: https://github.com/dfuenzalida/adventofcode/blob/master/advent2017/clojure/src/advent/day03.clj

The problem statement is the following:

Part 1

You come across an experimental new kind of memory stored on an infinite two-dimensional grid.
