I just made my machine learning code work a few days ago and I would like to know if there's a way to improve my code.
Before I get to the implementation of the tasks at hand, I would like to introduce the design I have in mind.
I first created interfaces containing methods that are the tasks n...
Is there a better practice for using a fallback value when a user environment value isn't present?
My current thoughts are to treat it as an ternary condition and use a match or if else statement:

I recently applied for a Java developer position and I was asked to completed a coding task.

I want to plot (on the complex plane, with mpmath) the power series whose general term is the number of partitions of an integer.
The more points I want (and the larger the degree is), the longer the plot takes.
