Yes the site is still working and under active development, and the Code Golf community is active but a little quiet at the moment. More challenges welcome...
There's also a Discord channel (see the link in the right hand panel, or the bottom of the page on mobile). (more) |

I suppose technically I should say "I don't know if you want both sides changed or just the right". I really don't feel qualified to guess in this challenge. (more) |

There appears to be a typo in the reduced end result in the "Task" section:
> reduce that result (e.g. `EENWNWESWESW` -> `EENWWESW`)
I haven't made an edit because I don't know if you want the left or right hand side changed. (more) |

A: Slow animated open of leaderboard to avoid misclicks I'd be happy with the approach suggested in the question, but even better would be server side support for a leaderboard, so it is present immediately when the page loads, and there is never a jump in the interface. This would also allow the leaderboard to be displayed for users who browse wit... (more) |

Just as I start to press the mouse button, the leaderboard finishes initalising and the page jumps as the leaderboard appears instantly, and I click on one of... (more) |

Welcome to Code Golf Codidact!
It's worth being specific about what is meant by "display". Does this just mean any output (such as displaying on the screen or the return value of a function) or does it mean something more restrictive?
The defaults are described in [Default Rules: Code Golf ... (more) |

Sounds useful to catch that in future answers. I've commented under the challenge to suggest it. (more) |

Does [Revision 4](https://codegolf.codidact.com/posts/295964/history#4) mean that additional test cases would have caught this earlier? Do you have a suggestion of a test case that would help? (more) |

I agree it's a higher bar in general (particularly because different people will disagree on what level the algorithm should be analysed at - is a particular example really an O(N) algorithm if it uses a built in which is probably O(N²) in the language implementation?).

I proposed [empty output for zero](https://codegolf.codidact.com/posts/282784/295346#answer-295346) on Meta as a default rule a few months ago. It currently stands at -1 votes. Anyone reading this, please add comments and up or downvotes there so consensus can be reached.

Sounds good. In that case it would be worth editing to say that, since otherwise an explicit requirement for a single argument overrides the defaults. (more) |
