Warning: This challenge is only valid for languages with a compiler.
Make a program (which is perfectly valid code) that outputs Hello, World, even before runtime.
How? Let me explain.
Many languages have a compiler. Some operations are made in the compile-time, and others, in runtime. You...

Create The Correct Path
Which would be better code golf with shortest code and being able to run on at least two operating systems or code challenge and scoring by how many operating systems it can run on?

Given an input create a program that when ran ...
Lorum Ipsum Generator
Lorum Ipsum is placeholder text used when preparing layout without wanted to have content already filled.
One of it's key features over using some arbitrary text is that it is nonsense.
It isn't even valid latin (though it is close).
This prevents anyone being shown the la...
Continuing my It was just a bug challenge:
Input:
A string consisting of printable ASCII characters without white-spaces nor new-lines.
Output:
First turn the input into a palindrome by reverting the input, and adding it before itself, excluding the middle character (i.e. with an input 123456...
Goal
You are given an integer n. You need to count from 1 to n without any consecutive numbers. Your program must output how many combinations can achieve this.
We will call f(n) the function that takes in n and output the numbers of valid combinations.
Example
For n = 6, a possible solutio...
Warm up: Regex, Paper, Scissors
This is the challenge I originally wanted to post, before realising that some very short solution exist. Nevertheless, it can be an interesting problem to think about in preparation for the actual challenge below.
Write three regexes R, P and S such that they mat...
You might already be familiar with the game: Basketball FRVR in facebook. There are two types of score you can make:
A virgin-shot:(we call it so in our country :D) When the ball enters the basket without touching the rim or
A stale shot: When the ball enters the basket, but after touching the...
I like to ask fastest-code questions. However, I don't want to run everyone's code on my PC, partly because I only have access to a slow Windows laptop at the moment and I can't imagine I could even run most code in most languages.
Is it acceptable to ask people to include a TIO link in their...
Is it true that the first C compiler was written in C itself? Then, how was it executed and compiled? Or, was this compiler written in assembly language?
In golf, the standard scratch of a course is calculated using this formula:
(3*num_of_3_par_holes + 4*num_of_4_par_holes + 5*num_of_5_par_holes) - difficulty_rating
Your task is to calculate the standard scratch of a golf course, given these 4 inputs.
You should take input in any standard for...
In this challenge, you are given two overlapping rectangles, and you need to calculate the rectangles created by removing one from the other.
For example, if you remove the red rectangle from the black one:
You end up with one of the following two rectangle sets:
You'll also need to handl...
You must write code to print out your answer. The answer must include the following: Your code, byte count, name of language and the formatting style of TIO (H1 header for bytecount/language name, and formatted code.)
Rules
Code-golf rules.
You may add other items to answer not included here.
