Finding test cases that work under several different types of rounding sounds like a good compromise - I hadn't considered that. This might allow you to write just one set of test cases that works for all approaches, which sounds much easier to work with. (more) |

Generally I prefer a challenge to be specified in terms of its output, rather than its internal workings. So "the output must meet these criteria" rather than "you must use this algorithm". It is easy to verify that the output is correct, whereas it is difficult to prove that a particular algorithm i... (more) |

The other problem with having many permitted approaches is that it becomes more difficult to write test cases. I recommend adding test cases to make it easier for people to check their own and each other's answers, particularly if unexpected edge cases appear. It is still possible to write test cases...

I never know how much flexibility to include in a challenge. I want the challenge to be flexible enough to allow as many people and languages as possible to enter. I also don't want too much flexibility as this puts a burden on the people solving the challenge.
For example, if there are 2 permitte... (more) |

I wanted a unique name for each compass point, in the same way that real compass points have NW but not WN.
I'll think about whether that requirement could be dropped, and I'll also think about how it could be better explained if I keep it. (more) |

(Note that the test case failures are not related to the suggested change - they are already failing.)
In case it's helpful (or in case I've made a mistake), the code I used for testing is [available as a GitHub gist](https://gist.github.com/trichoplax/bc5dcc53c6bdd111a3a51c294fc86df9). It gives t... (more) |

The good news is you can save a byte by not putting the `return` on its own line.
The bad news is some of the test cases fail. (more) |

I'm sorry for overlooking the other question. I have now edited the challenge to state that a maximum input length of 16 characters must be supported.
This is based on the previously existing rule
> Provided your output is correct for each input, your code is valid
combined with the longest ... (more) |

| Comment | Post #287207 |
In hindsight, it might have been better to make the input a single character, so that there is only one challenge (the conversion), separate from processing a string or other sequence type.
I will bear this in mind when designing future challenges, but I'm going to keep this challenge as it is (re... (more) |

| Comment | Post #287207 |
Interesting question. I see that as a separate, slightly smaller, challenge. If you write code that works for a single character, then to be a valid answer here it would need to also include the code to call that for each character in the input. (more) |

1. This is codegolf.codidact.com for recreational coding. For help with coding errors you can ask at software.codidact.com

I can't see any problem that could be caused by having a random button on a Meta category (Codidact Meta has had one all this time with no complaints...) so personally I'm in favour of just removing the restriction and having a random sort button for every category. (more) |

I couldn't find a way to shorten this, just ended up with the same length. You can use `0` instead of `-1` but only if you add an extra character to the string to prevent the index ever being zero, so it costs a byte to save a byte...

Would the first sentence be clearer with the "of" replaced by something like "such that"?
