A: Multiply two strings Scala, 25 bytes ``` a=>.flatMap(a map .min) ``` Try it in Scastie! Pretty trivial solution, but here's a bad explanation anyway: ``` //a is the first string a =>.flatMap(a map .min) //b is the second string, x is each char in b a => b => b.flatMap(x => a map x.min) //For every char y i...

You can use an `else` instead of the `continue`, and you might want a slightly different input format to avoid the try/except stuff. However, I'd recommend taking a look at the other answers - you don't need `z` at all if you multiply by `x` each time and add the next coefficient (you'll have to take... (more) |

You can use `1` instead of `True`, use `n+=[a]` instead of `n.append(a)`, drop the both the `continue`s, and use `for a in n:` and then use `a` instead of `n[i]`. However, it'd be better to just use one loop instead of filling up an array and then iterating over it *again*. Even better would be a rec... (more) |

I can bet you 1 dollar (I'd bet more but don't have the money) that most of the answers will simply copy fizzbuzz, rot13, 99 beers, etc. from other answers on previous challenges without doing anything interesting whatsoever. Your typical answer would look like:
```
if input is fizzbuzz:

No, I didn't mean make a full-fledged golflang, just use pseudocode or maybe take a subset of Python/C/whatever without multiplication and exponentiation. (more) |

| Comment | Post #283341 |
What counts as a multiplication/exponentiation builtin is quite poorly defined, and although many languages might get by without them just fine here, they might not for other sorts of challenges/other builtins. I'd advise against banning them. One alternative is to create your own mini language for t... (more) |

Reduce over the range [1..n] Task I often need to find the factorial of a number or the sum of all numbers up to a number when cheating on math tests. To help me with this, your task is to write $F$, a generalized version of those functions: $$F(n) = 1 2 \space ... \space (n-1) n$$ Please note that the operator $ $... (more) |

I see. Does Corsaka's answer count as a consensus? It's got 5 upvotes and no downvotes, and there aren't any answers that advocate *for* giving rep. (more) |

Thanks for clarifying that in the draft, but I don't like the error handling part. It doesn't add anything to the challenge and is just cumbersome. Much better to simply say that everything that's currently in the error handling section is just undefined behavior. (more) |

This is a bit embarrassing, but I can't tell if sandboxed posts still give rep, since I don't get a notification for reputation here like I would Somewhere Else. However, I'm about 70% sure I got rep off of a draft in the Sandbox, so if they do still give rep, could that be turned off any time soon? (more) |

What do `^^^` (`^ 3`) and `//` (`/ 2`) return? As far as I know, they aren't used as unary operators in math. Is this simply undefined behavior? (more) |
