As we don't have any prior examples of [fastest-code](https://codegolf.codidact.com/categories/50/tags/5329 "Posts tagged fastest-code") challenges, I've posted in the Q&A section asking for general advice on [Hosting fastest code challenges](https://codegolf.codidact.com/posts/287927) to see what id...

Question | — |
Hosting fastest code challenges When posting a fastest-code challenge, what do I need to bear in mind? Unlike with code-golf challenges, where the score is simply the number of bytes in the source code, for a fastest-code challenge the time taken to run will be different on different machines. What options are there for defining... (more) |

(You can always "undelete" your own posts that you have deleted, so it works as a way of temporarily preventing answers.) (more) |

I missed your post while typing - sounds like you're fine with running on your own machine. Once you have copied this into the sandbox you can simply press delete on this one - it will remain visible to you but no one will be able to post an answer which means you'll be free to change whatever you ch...

We don't yet have any examples of [fastest-code](https://codegolf.codidact.com/categories/49/tags/5329) challenges - yours would be the first.
If you made this a code golf challenge (shortest code) then it would be simpler for you, but would still benefit from some test cases.
If you keep it as... (more) |

Welcome to Code Golf Codidact! This looks like an interesting challenge.
It might need some fine tuning to make it clear how to calculate the score for generating the automated leaderboard. For example, the run time will differ on different machines. We usually post our challenge ideas in the [San... (more) |

If we label an answer as invalid but don't delete it, then currently I'm guessing it still appears on the automated leaderboard? If it's decided to go with this approach maybe we could look into amending the leaderboard to not include invalid answers. (more) |

Is it straightforward to remove this reaction once the answer has been fixed? I guess the thread could remain as history as long as the reaction badge can be removed? (more) |

Answer | — |
A: How should we handle incorrect answers? Respect both sides We should consider how an approach would affect the poster of the incorrect answer, and how it would affect the posters of correct answers. Correct answers In general, allowing an incorrect answer to remain leaves some or all of the correct answers lower in the automated per l... (more) |

I think it's worth taking into account that an answer appears in the per language leaderboard below the question, so allowing it to remain in place can give a casual observer (particularly one not familiar with that language) the impression that it is officially approved and correct.
For example, ... (more) |

Shortest representation in generalised Roman numerals [FINALIZED] Posted Given an integer, find its shortest representation in generalised Roman numerals. Since there is more than one way to generalise, only the definition shown below applies to this challenge. Definition The digits used are the same as for standard Roman numerals, with the same values: Dig... (more) |

Question | — |
Digit antitranspose Convert a matrix or grid of digits to its antitranspose. For a square matrix , this is its reflection in its antidiagonal. More generally, for a rectangular matrix, this is its reflection in its skew diagonal. Less formally, the line to reflect in is from South West to North East, at 45 degrees re... (more) |
