An application built as a recruitment task

WaterOnMars

It's a solution for the recruitment test. The objective of the exercise was not optimizing every drop of performance, but applying appropriate algorithms and data structures to the task and providing cleanly version-controlled, runnable solution that is tested, readable, employing patterns and language features of the kind that I'd want to see in code that I would be tasked to maintain.

Prerequisites

• Install Elixir
• Install dependencies with mix deps.get

Sensor Processor

You can run the Sensor Processor by entering the following command:

mix water_on_mars.process_sensor_data "<<raw_sensor_data>>"

For example:

mix water_on_mars.process_sensor_data "3 4 2 3 2 1 4 4 2 0 3 4 1 1 2 3 4 4"

The command output will be:

(1, 2 score: 27)
(1, 1 score: 25)
(2, 2 score: 23)

Heatmap

You can also process the data and generate a heatmap. In order to do this, start your Phoenix server:

mix phx.server

Now you can visit localhost:4000 from your browser.

Tests

You can run all tests by the following command:

mix test

Dialyzer

You can run Dialyzer by:

mix dialyzer

Credo

You can run Credo linter by:
