A: How should we handle incorrect answers? Lock it Locking a post disallows edits, comments and votes. I am not sure if it allows the original poster to edit or not, but this would be one way to preserve the answer while preventing interaction with it, possibly allowing it to be fixed in the future.

How should we handle incorrect answers? Recently a flag came to my attention on this post: https://codegolf.codidact.com/posts/280372/281943#answer-281943 It is a well-intentioned answer to the challenge, but unfortunately it is wrong, and despite being notified, the user who posted the answer has not fixed it. What should we do in ... (more) |

A: Under which condition is a function that takes arguments other than those specified by the challenge by itself a valid solution to a challenge? What you said > a function is a valid solution to a challenge if and only if it can be called with no more than the specified input of the task This sounds reasonable to me. If you want to make your function take in specific parameters, code in defaults, or write a program instead. (more) |

A: Tips for golfing in Java Use higher versions of Java Seriously, it's crazy what sort of features have been added since Java 8. I hardly recognize the language anymore...

A: Default Rules: Code Golf I/O You may modify the input in-place If a function takes an input `a`, it is acceptable that `a` contains the intended output after executing instead of other forms of output. Note that this means `a` must be mutable to begin with and the function must actually mutate `a`. Example (more) |

A: What's a code bowling challenge? It's the opposite of code golf. Code bowling is essentially a challenge where you try to write the longest code possible, as opposed to the shortest code. Now, this format comes with many issues, and you may be able to see why. For example, just adding comments increases code length - you need a v... (more) |

Three Number Monte The Rules In this game, each round, every player faces off against every other player in a round robin format. In each match, players pick 3 positive integers that sum to 360. Let's say player 1 picks `[a, b, c]` and player 2 picks `[x, y, z]` Now `a` is compared to `x`, `b` is compared to `y`, an... (more) |

A: Default Rules: Random Every outcome must be possible For example, if the challenge requires a random number from 1-5, all 5 numbers must be possible. It does not need to be uniformly random (unless otherwise specified) - all 5 numbers may have different probabilities of occurring, but they all must have a nonzero proba... (more) |

A: Default Rules: Flags and Other Compile-Time Options IF flags take arguments, those arguments count for the code length For example, in Japt, `-F"string"` is a flag that prints `"string"` if the output is falsy - in my opinion this should add 6 bytes on to the length of the answer (in language `Japt -F`).

A: Default Rules: Code Golf I/O Functions may use arguments or lists of arguments interchangeably For example, if a challenge requires defining `f(x, y, z)`, `f(a)` is also acceptable where `a[0] = x, a[1] = y, a[2] = z`. (more) |

A: Is my extension-like library allowed to be used in answers? Yes, including the fact that it's in C. Using a heading such as "C + BMPL" that links to the library and explains what it does should be fine. I also think that having a way to run it (preferably in one line) to verify solutions would be nice. (more) |
