Comment Post #293001 If placeholders are not permitted in answers, but are used in an example, I would expect some people to (understandably) misinterpret the rules. I would expect less confusion if the example were also valid as an answer. If there is no way to express the rule "can duplicate any string that comes af...

Comment Post #293001 Does this mean that it is your intention to allow placeholder strings in answers too, not just in the example? If so it's worth making that explicit in the "What is a rewrite rule?" section. Currently it would be easy for someone to interpret that section as only allowing direct use of symbols in the...

Comment Post #293001 The section "What is a rewrite rule?" makes clear that the 2 strings can only contain symbols from your alphabet. However, the example of impossibility has rewrite rules that include placeholders x and y that are not symbols from the alphabet "MIU". If you would like the example to be consistent w...

Comment Post #293089 There is nothing wrong with not posting in the Sandbox. I mentioned that I use the Sandbox in case that would be helpful for future challenges. There is no obligation.

Comment Post #293089 > **You do not need to return all possible permutations of one single array.** Does this mean that you are *permitted* to return only one permutation of each quintuplet, or that you are *required* to return only one permutation of each quintuplet? The distinction is important because in some pr...

Comment Post #293089 Most challenges require fine tuning, so I post mine in the [Sandbox category](https://codegolf.codidact.com/categories/50) to avoid any answers arriving until the wording is free of potential ambiguity.

Comment Post #293089 In addition to editing to make the correct interpretation explicit, it would be helpful to have some test cases for this specific situation. For example, what should be the output for the following input: ```text -1, 1, 1, 1, 1, 1, 3 Target: 5 ```

Comment Post #293089 > In the case of multiple arrays, we also add the requirements that at least two values in each of the arrays are distinct. Does this mean "for each pair of quintuplets, each quintuplet must have at least 2 elements not present in the other", or the stronger "for each quintuplet, at least 2 of its...

Comment Post #293089 > - In the case of multiple arrays, we also add the requirements that at least two values in each of the arrays are distinct. The problem specification refers to an array of quintuplets. Does "multiple arrays" here refer to multiple quintuplets?

Comment Post #292936 In general, I would much prefer to avoid rule changes. In this particular case, I can't see a way to have spotted this ambiguity before answers arrived, and now that answers have arrived, either way of resolving the ambiguity will disadvantage half of the answers (it was just a matter of choosing whi...

Comment Post #292936 From my perspective, the new wording appears to be a change, which I'm uncomfortable with for the same reasons as you. However, my impression is that from the challenge author's perspective, this is a clarification rather than a change. The wording in the comment on the challenge supports this: ...

Comment Post #292936 I've asked for clarification from the challenge author, and the challenge has now been edited to indicate that rounding of 33.33 can be to either 33 or 34, and an extra test case output has been added, so the online test case for `F 3 2` is correct.

Comment Post #292935 A number of the current answers show 34 lots of `|` instead of 33 for the second test case (Input: 2/3). I have assumed that 2/3*50=33.33 must be rounded down to 33, rather than up to 34, and added comments to the relevant answers. However, it occurs to me that some people may interpret your round...

Comment Post #292936 I also couldn't see a way to run the code at the time the answer was posted, but there seem to have been some improvements to the interface since then. There is now a "Run" button to the lower right of the code, which displays the output for the 4 test cases. One of the test cases is off by one, s...

Comment Post #292939 The online test cases give only 49 characters (51 including the `[` and `]`) rather than 50 (52 including the `[` and `]`). Also, the second test case uses `1/3` instead of `2/3`.

Comment Post #293005 I haven't tested this, but could you save a byte by using `>` instead of `<=`? I'd expect this to avoid changing the rounding in the way that `<` would.

Comment Post #292920 Since you mention rounding, it might be worth mentioning the behaviour expected for decimals ending in 5. Some places always round up (2.5 rounds to 3, 3.5 rounds to 4), but other places (particularly statistical or scientific settings) have other rules, such as [round to even](https://en.wikipedia.o...

Question Advice for hosting a language agnostic King of the Hill contest
A King of the Hill contest requires that a controller program provided by the person hosting the contest communicate (both input and output) with each of the entries to the contest. For some contests these entries may be functions to be called by the controller, and in other contests the entries may ...

Comment Post #292756 The idea is not that the input would come into the program through function parameters, but that the function would be called from within a larger program, and the program would call it using arguments as input. This allows competing to find the shortest function that solves a problem, rather than to...

If they were posted in a single answer, th...

Add TODO for checking choice of sphere makes little difference

Comment Post #292000 Since all of the surface patterns in the test cases are formed by overlapping spheres to take advantage of this effect, I will double check before posting that either choice of which sphere's colour to display gives sufficiently similar output images.

Comment Post #292000 When 2 spheres A and B overlap, there are 3 types of overlapping points: - The surface of A is inside the surface of B (so the nearest intersection will be B). - The surface of B is inside the surface of A (so the nearest intersection will be A). - The 2 surfaces meet along a circle (infinitely th...

Comment Post #292000 Good question. Short answer: I should make explicit that the code can choose either. I will edit accordingly.
