Comment Post #290667 I find this much more clear. Potential improvements: - The explanation section at the end could be broken up with subheadings or a numbered list. - The heading "Explanation" might be better changed to something that makes immediately clear that this section is optional. Perhaps "Background" or "R...

Comment Post #290667 This appears to be an interesting challenge, wrapped up in an interesting but unnecessary concept. The challenge would work without the concept, and be understood by more people. For this reason, my personal preference would be to have the simple statement of the problem at the start of the challe...

Comment Post #290200 I believe convention is to include any imports in the total length of the code. I couldn't find a Meta post specifically about this, but it is mentioned in an answer to another Meta post: - [Default Rules: Libraries](https://codegolf.codidact.com/posts/282802/282803#answer-282803) > However, yo...

Comment Post #287238 I try to post a range of golf challenges, because some people want a very simple challenge that they can tackle quickly on a short break, while other people enjoy a more complex challenge.

Comment Post #290106 I don't know Haskell, but I tested your latest code using the following: ```haskell main = do let result = map(\n->(scanl(*)1$cycle[5,2])!!(length$takeWhile(/=n)"IVXLCDM")) ['I', 'V', 'X', 'L', 'C', 'D', 'M'] print result ``` This gives the correct results for all inputs: ```text...

Comment Post #290104 I haven't tested the Haskell code, but there's a problem with the Python code that I'll explain below. In Python, a lambda function cannot have multiple statements. If you try to run the current code, it will give an error. I can think of 2 different approaches to avoid this problem: - Use a `lam...

Comment Post #290106 The same applies to this answer as I [mentioned on your Python answer](https://codegolf.codidact.com/comments/thread/8720#comment-22430). It just needs an input method to make it valid.

Explicitly exclude output as a Roman numeral

Comment Post #289996 Good point. I will edit to make explicit that output in Roman numerals is not acceptable. As for choosing a text encoding where the output always equals the input, I would likely vote to agree that should be a forbidden loophole if you added it to [Code Golf - Default Rules: Loopholes](https://cod...

Comment Post #289996 I'm happy to stick with the [defaults for I/O](https://codegolf.codidact.com/posts/282784) unless there's some loophole I need to close. One of the answers there mentions using a character code instead of a number, which would allow outputting 1000 as "Ϩ" (unicode codepoint U+03E8) but I'm not sur...

Nothing broken, but just an observation in case it wasn't intentional: I notice that the test cases match the examples, with the exception of the example "TWO BIRDS WITH TWO STONE", where the test case differs: "TWO BIRDS WITH ONE STONE".

Comment Post #287403 I decided to go with negative and zero inputs. I restricted the input range to -72 to 72 so that no output would be more than 8 characters long, but the test cases exceeded the post length limit, so I further restricted the input range to -62 to 62.
