ASCII characters are all Unicode characters with code points from 0x00 to 0x7F (both inclusive).
Printable ASCII characters all are Unicode characters with code points from 0x20 to 0x7E (both inclusive). This does not include linefeeds.
This is consistent with the definition of printable charac...

Write a program that, in different languages, output a different permutation(the exact source is counted as one permutation) of the code.
Proper quine rule apply. Largest (Language count)^6/(Code length) win.
Sample: If your code is AAB and running in several languages return ABA, AAB, AAB, the...

Scoring a Game of Composite Boards code-golf
The Game of Composite Boards
Given a board size n which must be a composite number, the game is played on m boards in parallel which correspond to the factors of n, excluding 1 and n itself.
E.g. if n = 12, we get the following 4 boards, where the s...
Description :
You are given a string of numbers (positive and negative but not decimals) along with the number of entries like so.
Like so
8
'1 2 5 0 7 -9 12 - 8'
Task :
Your job is to return the number closest to zero be it +ve or -ve. Your input will be separated by spaces only. You are f...
Given an arbitrary Sequence consisting of 1 and A
split this sequence up so that A is at the beginning of each sub sequence.
Sequences without a leading A and Sequences without 1 before the next A will be self contained.
Example
Input
111A11A1111111A1A1AA
should result in
111
A11
A1111111
A...
Pristine and Unique Code Bowling

Your challenge is simple: write as long of a pristine program as possible in the language of your choice using only unique printable ASCII characters.
That's right, no strings attached. Your code doesn't have ...
50 rep for the shortest "Hello, World!" in Pepe
If you can beat this, I will pass a 50 bounty for you.
Well, my solution uses character constants. They span a bit of place and I bet a shorter solution is possible, even if it's going to be extremely hard. 50 rep is definitely not enough here, bu...
Rotational Average
code-golf number-theory
A little bit more simple challenge than usual for me, so please let me know if this is too simple.
Given an input integer n >= 10, output the average of all deduplicated rotations of the integer.
For example, for input 123, the rotations are 123 ...

This is an ascii-art CC-BY-SA problem from CCSC Mid-South Programming Contest 2018, that I found enjoyable. I think there are probably a good deal of code-golf optimization opportunities available as well.
The original statement used MathJax for math rendering, so any suggestions on how to refor...
Make a Walsh Matrix
code-golf math matrix
A Walsh matrix is a special kind of square matrix with applications in quantum computing (and probably elsewhere, but I only care about quantum computing).
Properties of Walsh matrices
The dimensions are the same power of 2. Therefore, we can refer to...
Assignment is simple to explain: write the shortest code you need to determine whether an executable binary program supplied as parameter is 32 or 64 bits.
If there is a different kind of bitness, you can also do for it, but is not mandatory.
What I really don't want is telling me you support o...Anonymous
