I've had similar bugs IRL. It's good to be aware of such issues, nice kata.

100k data sets for a 7kyu kata is overkill. That's why raiting falling pretty bad.
I suggest limiting the amount to 1k and do not bother with efficiency (because that would put the kata in 6kyu category).

As a reminder:
https://docs.codewars.com/curation/references/kata-ranks#7-kyu

The kata description could be more Python-oriented for sure, but the instructions themselves are fairly clear and straightforward. Additionally, there's already another issue addressing this, making a second issue seems redundant.

IMHO current constraints makes it 6kyu.
At 7kyu brute-force solutions should be accepted.

I like the idea of this Kata, but you can get away with just half of the solution because tests don't cover all of the edge cases.

I can't believe nlogn solutions get so many best practice votes... 🫠

C# starter code contains:

#TODO: write your solution here

Which causes an error:

src/Solution.cs(6,14): error CS1024: Preprocessor directive expected

"#" in C-Sharp marks the beginning of a preprocessor directive.
"//" should be used instead for one line commenting.

Yeah, you're right. It's placed in a such way, you need to read every word in the description a few times in order parce the requirement.

Order is not mentioned in the task although it is required to pass the tests.

This kata should be retired or limit raised to 50 chars.
As in order to solve it, one has to use deprecated language features (and it is the ONLY solution to the kata).

For F# the description requires "Hi, i'am {firstName} {lastName} and it is nice to meet You."
But tests require different format "Hi, i'am {firstName} {lastName} and is nice to meet You."
(Test is missing "it" after "and")

Enjoyed writing my first Forth function. Seems a bit hard for 8 kuy, 7 would be more appropriate.
