Believe it or not, we do not yet have a code golf challenge for a simple primality test. While it may not be the most interesting challenge, particularly for "usual" languages, it can be nontrivial in ...

Input: Two integers. Preferably decimal integers, but other forms of numbers can be used. These can be given to the code in standard input, as arguments to the program or function, or as a list. ...

This challenge is quite simple. You will take an input which will be a year from 1801 to 2400, and output if it is a leap year or not. Your input will have no newlines or trailing spaces: ...

This is tangentially related to my quest to invent an esoteric programming language. A table of the binary numbers 0 .. 15 can be used to implement a Universal Binary Function using indexing ...

Stackylogic is a logic-based programming language I made up that take in 0's and 1's for input and outputs a single ...

In one of our projects at work, we recently discovered a particularly large method for generating a 6 character string from a 15 character alphabet. A few of us claimed "I bet we can get that in one ...

Based on my previous question of the same type, Build an adding machine using NAND logic gates, this time you're being asked to multiply instead of add. Build a diagram of (two-wire) NAND logic gates ...

Scoreboard Here are the raw scores (i.e. domino counts) for VisualMelon's submission. I'll turn these into the normalised scores described below, when more answers come in. The existing solution can ...

A 2-way universal logic processor (2ULP) is a network of logic gates that takes two input wires A and B, as well as four other ...

A bit-counting comparator (BCC) is a logic circuit that takes some number of counting inputs A1, A2, A3, ..., An as well as inputs ...

In this question, a mapping is defined between EBCDIC and a superset of ISO-8859-1. Your task is to build a network of two-input NAND gates that will take eight inputs ...

This is "programming" at its most fundamental. Build a diagram of (two-wire) NAND logic gates that will take the input wires A1, ...

A minifloat is a binary representation of a floating-point number that has very few bits. The minifloat in this question will be defined as an 6-bit number m, ...

Given two numbers, print a page with an "X" in the specified location (±10%). The numbers must be either percentages or fractions of the page's print area dimensions, e.g. ...
