The Crystal version of this has what seems to be an error. The example shows that the triplets variable is a 2d array of chars but one of the tests has a 2d array of strings. Can someone confirm that that is an error or are we suppoed to be able to handle strings as well?

Is there consistent compiler support for C++20 outside of MSVC? But yeah, I agree it would be nice to have.

It would be good if the website accepts C++20.
It only accepts C++17 as of now (10/2022).

Uy, brain fart. I meant new right column.

for j in range(i, len(array)):

It is creating a for loop that iterates from i to the length of the array. It is used to compare i to all of the remaining elements in the array.

No, the tests are just bad, and there're already many issues about this. Also, not a suggestion.

I feel like a lot of the Python solutions wouldn't work if the tests were good. Could be that I misread the description though and this kata is more lenient with its requirements than I first thought.

It's solutions like this where I'd appreciate a downvote button.

My solution is way overcomplicated but it works and I have finally conquered this super difficult (at least in BF) kata.

The obvious solution. lol

Easy while using a certain Lib, but try doing it without it

While reading the C++ solutions I can't help but think that they're all really ugly because the standard library lacks a concise and intuitive string formatter. It will be nice when C++20 is available everywhere and we can get our hands on the new <format> library.
