The Challenge Generate 1 sec of an 8 bit tone sampled at 256 samples per second. The tone will be made up of a number of sine waves. The frequency of each sine wave will be determined from the input data. These are deep tones, too low for a human to perceive, but I've chosen 8 bit numbers here ...

Map out ASCII keys as the user presses them code-golf ascii-art ascii The ASCII charset (American Standard Code for Information Interchange) is the most widely-used character encoding standard. ASCII codes represent text in computers, telecommunications equipment, and other devices. Challenge ...

Need a formula for something a bit odd. I have random numbers that I get and I need them to be in 2 groups of 3, with both groups being as close to each other as possible, but no numbers can be duplicated. So, if I got say 1,2,3,44,12, 5,7, 9. I would have group A as 1,3 and 9 for a total of 13 a...

Generate more efficient US state codes Abbreviate that US state! was fun, but we learnt that efficiently abbreviating US state names is hard with the current system. Let's come up with an alternative state code scheme for efficient golfing. Your task: Write a function (or program) which, gi...

Recently, an electrical engineer studying traffic light timings was fined $500 by the state of Oregon for referring to himself as an engineer. Given a 2 letter string as input, representing a US state, output I am not an engineer if the state is Oregon (OR), I am an engineer if the state is any ...

Related Task Your task is to calculate the new Elo rating (FIDE rating system) for a player after winning, losing or drawing a game of chess. To calculate the Elo rating two formulas are needed: R' = R0 + K*(S - E) E = 1 / (1 + 10 ^ ((R1 - R0) / 400)) where: R' is the new rating for playe...

Let's not collide Contextualization You might have heard about Re-Volt, a pretty old video game. Its collision system for cars is somewhat interesting : the body of the vehicle gets transformed into a simplified 3d convex shape which is then filled with spheres. Challenge Your objective is ...

Given an ASCII representation of a piece of string, determine its length. Input An multi-line ASCII rendering of a piece of string, which runs from top to bottom, with one 'node' (corner) on each line of input. The delimiter may be assumed to be CR, LF, CRLF, or LFCR. Input may be accepted from...

Concept Remembering numbers can be difficult. Remembering a word may be easier. In order to memorize big numbers, I created a way to pronounce them in a leetspeak-like way. Rules Each digit is first replaced by its corresponding letter: 0 => O 1 => I 2 => R 3 => E 4 => A 5 => S 6 => G 7 => T 8 =

Lets play golf while we golf. Problem: Distance to the hole initially is 700m Each hit to the ball will make it advance to the hole 250-350m, this should be random. Each hit has a 5% probabilities of going into water, this will make the quantity of hits increase by 1 as a penalty. When ball ...
