You have played \$N\$ matches in some game where each match can only result in one of the two outcomes: win or loss. Currently, you have \$W\$ wins. You want to have a win percentage of \$P\$ or more, playing as few matches as possible. Output the minimum win streak that you need. Assume the curr...

Consider such a question Take a program P and an integer n, check whether P halts. You may assume that if P halts then P halts in n steps. and solution 1 (P,n)=>!run(P,timeout=n us).timeout solution 2 P=>!run(P,timeout=9 us).timeout where S1 assumes n steps will finish in n us and S2 assume i...

Introduction The game Minecraft has a 1 in 10000 chance of showing "Minceraft" instead of "Minecraft" on the title screen. Your challenge Your challenge is to code a function or program that takes no input and, 1 out of 10000 times, returns "Minceraft" and the rest of the time returns "Minecraft"...

Solve the halting problem for /// substitution code-golf halting-problem /// is an esoteric programming language with simple two operations. One is to output its source to remove from it. The other is to substitute itself. This time I am assuming the case when the program is /pattern/replacement/...

You are Odysseus, and are finally free from Calypso (who has kept you captive for many years) after you drugged her while she was sleeping1. You wish to return to your homeland of Ithaca, but the ship you've stolen is a bit damaged and cannot steer. However, you have also stolen a map which conta...

You are to take in a Gelatin program and it's argument and output the result. Gelatin Gelatin programs will always match the following re...

Synopsis Your goal is to implement the (asymptotically) fastest growing function within bounded code on a fictional CPU utilizing a quite limited, yet (probably) turing-complete instruction set. Environment The CPU utilizes unbounded RAM as well as two registers, the accumulator A and the program...

The generalised harmonic number of order \$m\$ of \$n\$ is $$H_{n,m} = \sum^n_{k=1} \frac 1 {k^m}$$ In this challenge, we'll be considering the generalised harmonic numbers of order \$2\$: $$H_{n,2} = \sum^n_{k=1} \frac 1 {k^2}$$ This sequence begins \$1, \frac 5 4, \frac {49} {36}, \frac {205} {...
