I'm trying to get the shortest way (character possible) to obtain List 3.
List 1 and List 2 are already given to me as arguments.
l1 = [1, 2, 3, 4, 5]
l2 = ['a', 'b', 'c', 'd', 'e']
And List 3 should look like:
l3 = ['a', 1, 'b', 2, 'c', 3, 'd', 4, 'e', 5]
Introduction
I have some JavaScript code that uses Array.prototype.map to map an array of functions fns to their return values:
const fns = [() => 1, () => 2];
const result = fns.map(
fn => fn()
);
console.log(result); // => [1, 2]
Challenge
The challenge here is to rewrite this f...

Working on my recent esolang μ6 I found myself a neat puzzle: Given the set of all natual numbers and the set of all nested tuples over the natural numbers, find a bijection between those two sets.

Goal
Write a program that calculates the deal score from a deal result of Contract Bridge.
Input is a deal result like 3S +1 or 1NTXX =, as well as whether the declaring side is vulnerable. The deal result is given as a string, but you may demand an arbitrary way for the vulnerability input, an...

When we look at a rainbow it will always have the colors from top to bottom:
Red; orange; yellow; green; blue; indigo; violet
If we look at these individual rings, the red ring is of course bigger t...

Basically the same as iBug's question, which was deleted. I figured out this scoring system while trying to answer that question.
Goal
Given a deal result from Contract Bridge, calculate the deal score.
Input
Input is a deal result, and whether or not the declaring side is vulnerable.
