Lol?! Why is the user 'dlcoe' allowed to write something that stupid and even writing about "agressions" experienced by women (?!?!?!) just because it is unable to correctly understand a text? This makes me feel very uncomfortable (and I am pretty sure I'm not the only one...). Such frustrations should have no place 'on the path to software development'.

Maybe change the title to Test contraints ? x)

Description updated.

Performances and tests

sorry, I misread/misinterpreted this (this is definitely a bad day of those... :/ )

from what you're telling, there shouldn't by any perf requirement for the present one, so.

There aren't performance requirement.

There is the default 12 seconds timeout, but it shouldn't be a problem. Reference solution complete all tests in 120 ms (lesss than 2 s including startup and test case generation).

from what you're telling, there shouldn't by any perf requirement for the present one, so.

There isn't a specific algorithm for border drawing, and in this kata there are 3 solutions with 3 diffrent algorithms.

Different kata requirements may restrict the choice of algorithm. If there is a common algorithm it's a single kata (unless the algorithm is 90% of one kata and 10% of the other).

In this kata the main problem is avoid holes (which exclude some simple algorithm), in the second kata the main problem is speed (which exclude more complex algorithms), in the third is ... (top secret).

In general the choice of algorithm is free, in the second kata it's more forced, but in a performance kata it's normal to require the fastest algorithm and/or some micro-optimizations.

May be useful to have a comparative table in description?

IMHO it's a 5 kyu or maybe 4 kyu. My initial rank assessment is 5 kyu, as you can see from katas list.

Someone ranks everything 8 kyu (and downotes everything), someone ranks 1kyu easy katas. Min/max/avg ranks on kata page aren't very reliable, especially with few assessments.

Why is the level of difficulty of this kata pre-assumed at 7 kyu or even 6 (*_*)? The fact that you can solve it only with built-in functions (in Python) shouldn't ignore the experience in this area of math... (+ geometry code experience). I wouldn't dare to go and try (with a pretty long code, I assume) to transform in '-' and '|' some (between-)coordonates. So, why should one believe that this kata is easier (in any way) than the 4 kyu Snail (https://www.codewars.com/kata/521c2db8ddc89b9b7a0000c1), where you can definitely proceed with append only?

o_O How don't you understand your own solution @Blind4Basics

Trying to understand it myself. The recursion is messing with my head

WTF

me neither, that's the best part... XD

I still don't understand neither your solution nor the generator pattern...

try again using integers only, belieave me, it's the only way. I tried using float and double and the only "other" way is using double but adding a hardcoded amount of 0.000002 or something like that, which is not correct.
