Quickly calculate \$ n! \bmod p \$ fastest-codefactorial
The idea is extremely simple: Given two positive integers \$ n \$ and \$ p \$, calculate the result of \$ n! \bmod p \$, where \$ p \$ is a prime.
Scoring
Your score is the highest \$ p \$ you can achieve within \$ 10 \$ seconds, by runn...

@Λ̸̸ The problem statement feels like an unnecessarily complicated version of "given an infinite arithmetic sequence, compute the minimum length of a prefix with product divisible by 2^8"...
@user202729 The "divisible by 2^8" doesn't seem right here. Although I don't know how dynamic trunctuation can potentially affect the result than simply trunctuation at the end.
Inspired by this code review question, I am curious to see what happens if we turn that into a code golf challenge!
Description is easy, input is an array or any similar data structure with only unsigned integers, output is a boolean true if the number of odd are equal to the number of even numb...
The string "node" must be hard-coded in plain ascii to obtain a string with the value "node", which must be transformed into the string "deno".
You cannot include "deno", any other variations, any other subsets of the word "deno", or any other representation of it in your code.

As in that challenge, there is a 2-dimensional array of 1s and 0s representing people. In it, social distancing is maintained if and only if all 1s are at least 6 squares apart, where distance metric ...
Inspired by Draw this planar graph.
Your input represents an ascending sequence, e.g. 1 2 3 4. You can require the sequence as input, or you can just input the length. The explanation assumes 1-indexing but you can use 0-indexed or even a-indexed input if you adjust the algorithm appropriately.

Shorten the numbers
These numbers are taking up far too many bytes on my computer. Create a function/program to shorten any number using only Alphanumeric characters as the output.
Scoring
Scoring is based on optimized-output. Shortest number of characters produced for the following randomly g...
Inspired by Wizard creating a jewelry.
Given an input list of positive integers, calculate the minimum cost of creating the list from the following operations:
Appending a positive integer costs the value of the integer.
Incrementing the entire list costs 2.
Exchanging two consecutive elements...

Write a function or program that accepts one character (or a string of length 1) as input, and outputs the number of times that character occurs inside the code. Output may be to standard out, or as a return value from a function. This is code golf, so the shortest submission in bytes wins. Good ...
