For the application build, I have chosen sbt (which I had never used before).
To compile, from the lab_result directory type sbt.
After the build, type run at the prompt. The application will execute according to the configuration
in src/main/resources/application.conf.
I have decided to tackle this task in Scala, despite my limited exposure to the language. The motivation behind this decision is that the task could be easily destructured in sub-problems that could be reassembled together in a functional fashion, and Scala offers exceptionally good functional capabilities. Scala has also been much fun to me since I got to use it for the first time, less than a year ago. I have developed the business logic of the application according to few assumptions:
- The shape of the provided data is correct;
- There are no special cases beyond those present in the dataset provided.
Clearly this assumptions are reasonable for the limited scope of this task. I would not dare to assume as much in a more open-ended application.
