Good evening!

@Voile: So what are your suggestions? As I understand it, your whole problem is that you simply do not like this assignment. I don't understand how I should solve this problem if you don't offer anything constructive. Left at least a reference to those "quality standards" that you use.

Hello again!

First, I don't really understand what you are suggesting. Change title/description?

Secondly, the meaning of this kata is a numerical solution of the problem in a general form, and not an analysis of special cases, as in a playlist. That is, in your language of analogy - it is proposed not to build one random diagram, but to write an algorithm for creating such diagrams. That's the whole idea, to write an "image generator".

Thirdly, no one is adding fuel to the fire here. How offensive are these kata? What quality standards are you referring to?

"Avoid creating blatant duplicates, and use the idea which has not yet been widely used to create a kata." - This kata is not a duplicate.

"Do not use problems from other sites." - This task is not borrowed from other sites.

If you so actively insist on the low difficulty of this kata, then I will change its rank to 6 kyu and close the problem.

More than a day has passed, so the problems are closed.

Well then, this kata can also be called a "problem with a task for home":

And many other similar tasks...

Well, I'm also not sure about the rank of this kata. It's just that when I solved 4 kyu kata, I quite often encountered problems easier than this one (especially in the field of mathematics).

So far I have changed the rank to 5 kyu, but we'll see. As for the knowledge of other people in trigonometry, I don’t know yet. Let's hope that most people really know trigonometry in grades 7-10.

Regarding the link to the Russian-language resource. The Kata Design Guide requires citation of sources if certain elements of the kata are inspired by other sources. In my case, it just so happened that some elements of this kata were inspired by the Russian-language page, to which the link was made. Well, I think that for most users it will not be difficult to enable automatic translation for non-English resources here.

Good day!

Well, firstly, this problem can be solved not only at home (but, for example, in the subway, in nature, at work, in the theater and in the cinema). And in most tasks (if it's not sorting an array, although sometimes there too), the main difficulty is mathematics. In fact, the same algorithms are just a separate chapter of mathematics.

And what do you offer in the end? Decrease the difficulty of this task (increase kyu)?

Thanks for your feedback!

Added information content to messages.

Comprehensive tests include both fixed tests and random ones. Cases from the examples were taken out into separate “basic tests”.

Fixed the tests, now there should be no problems for floating point values during random checks.

The tags have also been fixed. (Though I didn't quite understand why puzzle is wrong)
