Abusing native number types to trivialize a problem
It is common practice to restrict challenges to cases where input, output and/or intermediate values of the algorithm of choice fit into the language's native number type. At least for input and output, this is generally assumed even if not sta...
Javascript ES6, 90 bytes
$=_=>[...(_=`$=${$};$()`.split`
`)[0]].map((x,y)=>_.map(v=>[...
v][y]).join``).join`
`;$()
Not bad, not bad.
Explanation
Here's the standard quine framework:
$=_=>`$=${$};$()`;$()
To modify, I just split the quine string along newlines and chars to create a matrix...
When writing challenges involving integer I/O, I always find myself having to type the same thing: You may assume that the input and output will not exceed the maximum representable range in your language. I think it would be useful if we had a default for integer ranges in challenges, to avoid n...
The sandbox post is really just a question which we use as a system to review posts (which is great and all), but wouldn't it be great if there could be like a dedicated review queue for Sandbox Post? Nobody made one so I took it upon myself to make one! After days and hours of work, I've finishe...
Temperature in a line of rooms
You have a line of rooms that are different temperatures.
1 2 3
1.2 | 3.5 | 4.0 | 3.7
The doors between adjacent rooms start out closed. When you open a door, the now-connected rooms average out their temperatures. For example, opening...
Write some code that takes a single string as input and outputs MSB-set aligned ASCII.
Only ASCII characters less than 128 (0x80) will be in the input. The output format is generated as follows:
For each character convert it to its binary representation, remove the MSB (always 0) and then add ...
Compress by Replacement code-golf
You are to take an input string, and then turn it into another string with a list of replacements which would turn this new string into the input string. The catch is that you must output the smallest such alternate string + list of replacements you can.
The in...
The goal is really simple. Receiving a string as input, parse all the HTML entities that correspond to the following characters (including their uppercase variants):
áàãâäéèêëíìîïóòõôöúùûüýÿ
Parsing rules:
Each entity starts with & and ends with ;
The first character after the & will be the ...
When will I have a binary car?
code-golf
I noticed that my car's odometer was at 101101 when I got to work today. Which is a cool number because it's binary (and a palindrome, but that's not important). Now, I want to know when the next time I'll have a binary odometer reading. Now, I can't rea...
