This is my first question in Code golf I found it in stack-overflow (originally in JavaScript however all languages are acceptable):
Render on screen NxN (where N in range 1-16) grid where each cell have black boundary and red number - cells are numerated in hex starting from left-upper corner t...
Task: write in any language which can generate images e.g. JavaScript, the smallest "put pixel" function. You can initialise screen inside that function or in separate code. The put-pixel function should consume 6 arguments: x,y,r,g,b,a where x,y pixel coordinates and r,g,b,a are color values (a ...

Calculate the Ultraradical code-golfnumber
What is the Ultraradical
The ultraradical, or the Bring radical, of a real number \$a\$ is defined as the only positive root of \$x^5+x+a=0\$.
The notation is \$BR(\cdot)\$. For example, \$BR(-100010)=10\$, since \$10^5+10-100010=0\$.

Can you imagine solving the NYT crossword puzzle without any clues? Maybe not with all of the creativity and new words and phrases appearing in modern crosswords, but with a fixed word list there's some hope. In this challenge, you create a crossword puzzle grid in which this is theoretically p...

Shuffling Sequence
code-golf number sequence
Consider an operation \$f_n\$ that takes a length-\$2n\$ list and performs a perfect shuffle on it, reversing the second half. For example, \$f_4 [abcdABCD] = [aDbCcBdA]\$.
Under composition, \$f_n\$ generates a cyclic group. That is, there exists s...
According to Wikipedia, Clock Solitaire "is a game of zero skill and is a purely mechanical process." That makes it the ideal task for a computer.
The rules are simple:
Shuffle 52 cards into 13 piles of 4 face-down cards.
Arrange 12 of the piles in a circle (corresponding to the 12 hours on a ...
Maximize the Hello, world's in code permutations
In this task you should output this exact string: hello world. However, here is the catch: you must output as many hello world's as possible in all of your code permutations. Identical permutations do not count(e.g. aa's permutations count as one ...
