You may assume all elements in the array are greater then 0.
Here is what to do:
You will first look at the element at index 0.
[2,1,4,5,3,1,8,20,2,4]
The element is a 2. This means that you will print every 2nd index --
assume indexes start at 0
[1,3,8,2] (index 2,4,6,8) You will stop pri...

When two (or more) distinct values are asked as 'boolean' input, you cannot input complete or partial functions
When I create a challenge and ask for a boolean or two 'consistent and distinct values' I mean it in the sense of a truthy and falsey value. Usually I leave the choice to the ones doin...
Last I checked, one did not need a diamond in their name to post questions tagged kolmogorov-complexity. I also didn't know that main site tags could be mods-only.
Oddly enough, when I'm in the editor it doesn't happen.
Does it have a square? (simple version) code-golf matrix
Given a matrix of 0s and 1s, determine if there are 4 points that are 1 and are the corners of a square.
Here's an example to clarify, with a possible square (in bold):0 0 0 0 0 0 0 1
0 0 0 1 0 1 0 0
0 0 0 0 1 1 0 0
0 0 0 1 0 1 0 0

Does the Riemann hypothesis hold?
number-theory code-golf math
I would like to earn a million dollars, and the hardest way to do it is apparently solving one of the Millenium problems, so let's focus on one: the Riemann hypothesis.
Now, how could I possibly ever solve it? By writing a computer...
Sort an Option String
Background
In C, there is a function to help parse command-line arguments: getopt.
Getopt takes the argument count (argc), the argument list (argv), and a string representing the options the program should take (optstring).
The option string (optstring) is a series of op...00:00 - 20:0020:00 - 00:00
