A chunk of symbols is a calculation Challenge Create a program that takes input of a string and outputs an integer using the following calculation system: - The string can only contain `+`, `-`, ``, `/`, `^`, `!` (or a different character; `!` is used here for demonstration), `(`, and `)`. - In this system, a character shows the...

@#53196 Yep. It also makes some cool calculations since GEMDAS is applied to it, meaning having a second character to present `+n` is a good idea to start with. (more) |

A: Reduce over the range [1..n] [C (clang)], 59 bytes c;f(int a,(b)(int,int)){for(c=a;a>1;)c=b(--a,c);return c;} Try it online! This program written by @Hakerh400 in the comments is basically how the other answers before this post existed actually did it, by a reduction sort of method. I'd like to thank them for ma...

Code bowling "Code bowling" In this code-bowling challenge, make an absurdly long program that prints out "Code bowling". - Obfuscate it as much as you could. - Comments and custom functions aren't allowed to make the program longer. - If any character in the code is missing, it won't run or it sends an error. - The progr...

I have no idea how you got those XOR values. It's kinda confusing what values are going in. (more) |

@#53196 Yes, you can use whatever character to replace `!`, but that also means you can't use `!` anymore if you used a different character.
Meaning `aaaa+++` is a valid input, which returns `7`, whilst `aaaa!!!+++` isn't. It'd be written `aaaa+++aaa` or `++++aaa+++` instead, which returns `10`. (more) |

Add detailed wikis and usage info on these tags In this request (not really a feature-request but still tagged so anyway), I'd like to have detailed wikis on tags and maybe usage information on them too. Currently, these tags have usage info in them: - code-bowling - code-golf - cops-and-robbers - fastest-code - king-of-the-hill I'd lik... (more) |

@#53196 I remember Kevin M. Mansour doing the same thing for "Caesar shift cipher", where they used a function to solve the challenge, so sure, that works too. (more) |

@#53588 Since we're focusing on integers, it's most likely integer division we'll be using. (more) |

@#53837 No, actually. It's basically the implementation of the operation from the preceding number. For example, `//` is basically `x / 2`. And I mentioned you CAN'T use symbols other than `+`, `-`, `!` and `(` at the very beginning of the input because it will return something to show it's invalid. (more) |

A: Tips for golfing in C Abuse (as few) libraries (as possible) We don't want to use too much libraries when playing challenges. Sometimes, libraries aren't used at all in some answers in C. What if we want to shorten some code? Functions do the trick, specifically built-ins. It's specified you don't have to apply the ... (more) |

@#53837 Simple, use `<a class="badge is-tag">something</a>`. This will give <a class="badge is-tag">something</a>. (more) |

I don't know what the <a class="badge is-tag">blackbox-function</a> is supposed to be, but yeah, this may seem like a cool repetitive calculation challenge. (more) |

However, I'm thinking not just having <a class="badge is-tag">code-golf</a> + <a class="badge is-tag">tips</a>, but also burninate the <a class="badge is-tag">code-golf-tips</a> tag as well, to give more room to store tags. In other words, for some reason, the tag list has a max scroll so you won't b... (more) |
