A: Weave Strings Together Scala, 60 bytes ```scala .map( map "".+).reduce(.zipAll(,"","")map(+)).mkString ``` Try it in Scastie! First, `.map( map "".+)` turns every string into a list of strings containing a single character. After, these lists of strings are `reduced` by zipping with each other, padding with an empty...

Should probably also add the first few values in the challenge itself instead of just having an OEIS link. Nice challenge (more) |

I would suggest saying that the quine should be payload-capable rather than talking about data sections, because I'm not sure what exactly that means. (more) |

+1. It might also be worth mentioning that you can have numbers before keywords without whitespace in between and stuff like that. (more) |

`Scanner` is not the only way to take input, although it might be the shortest. That has nothing to do with `Scanner s=new Scanner(System.in)`, though, which you can obviously inline. You're also not allowed to "hide" imports in the header: you need to include them in your bytecount, but here, I'd su... (more) |

Did you even try golfing this? The two variable assignments look entirely useless to me. (more) |

If they're just your stuffed toys and not television characters or something that people would recognize, I don't really see a point to the dialogue at the start. Only you would "get" it, so it doesn't add anything to the challenge. (more) |

A: Generalized Sort Scala, 64 bytes ```scala c=>.sortBy(x=>c.map((x)))(math.Ordering.Implicits.seqOrdering) ``` Try it in Scastie! A rather crude answer, but I'll come back later to golf it. It's rather simple, though - it simply sorts by the result of applying every comparator function to each of the elements. (more) |

I know you're probably still working on it, but when you add testcases, can you add some for negative integers too? (more) |

| Comment | Post #283880 |
I would say that for code-golf and code-bowling questions, including test cases should be mandatory, not just encouraged. On the other hand, C&R doesn't really need them. (more) |

Is there any way for you to drop some letters off the end too (or would that increase the byte count)? (more) |

A: Compute the determinant Scala, 130 125 bytes Saved 5 bytes by returning 1 like Hakerh400's great answer ```scala def f(m:Seq[Seq[Double]]):Double=if(m.sizem(0)(i)f(m.tail.map(r=>r.take(i)++r.drop(i+1)))-a} ``` Try it in Scastie! A recursive function that uses the first row for the Laplace expansion. Explanation ... (more) |

A determinant in 28 bytes or less without using numpy or other libraries? That's highly unlikely. (more) |
