Sign Swapping Sums
combinatorics math code-golf
Given a nonempty list of nonnegative integers [x, y, z, ...], your job is to determine the number of unique values of ± x ± y ± z ± ...
For example, consider the list [1, 2, 2]. There are eight possible ways to create sums:
+ 1 + 2 + 2 → 5
+ 1 ...
Challenge :
You are given an integer n as input. Your job is to create a diamond that is 2x the given number n.
Input :
Input is integer n and n > 2 ≤ 3000.
Output :
Output will be a string and it will be in form of a diamond consisting of + with an addition line at the start showing n using...
I've been recently playing through 'The Weaver' and I think it presents an interesting challenge for code-golf.
Premise:
The Weaver is a game wherein you are given a number of ribbons coming from 2 directions 90 degrees apart and your goal is to swap them at certain intersections to achieve a d...
Countries by Area
Challenge
Given two non negative integers a < b, output all countries, from the below Top 100 Countries, where area is between a and b: a<= area <= b.
Example
147500 , 180000 --> uruguay, suriname, tunisia, bangladesh
1100000 , 1300000 --> peru, chad, niger, angola, mali,...
Do you love watching cool timelapses of constructions or other massive work done in minutes? Lets make one here.
We will be looking at an excavator digging quarry, making pictures each day to see whole progress. And your task is to show us this process!
Quarry is defined by the width of its firs...
Introduction
Write a solver for integer linear programming.
Challenge
Your task is write a solver for integer linear programming (ILP). In ILP, linear inequalities of a set of unknowns (all of which are integers) are given, and the goal is to find the minimum or maximum of a linear function.
...
In a recent challenge, almost all answers use an algorithm that yields the wrong results due to floating point errors.
The challenge is/was not unclear, but there was no test case that led to the wrong results when most answers were posted.
Now, most of the answers are invalid, and should ther...
Background
I was inspired by 3Blue1Brown's recent video about the necklace splitting problem (or as he calls it, the stolen necklace problem) and its relationship to the Borsuk-Ulam theorem.
In this problem, two thieves have stolen a valuable necklace consisting of several different types of je...
Tower Defense

[Picture will go here]
Tower Defense is a format for casual games that was popularized in the Flash era. The player places towers that shoot down invaders moving along a predefined path.
The Challenge
There will be two typ...
Specifically, Conway's PRIMEGAME.
This is an algorithm devised by John H. Conway to generate primes using a sequence of 14 rational numbers:
A B C D E F G H I J K L M N
