Decompress an integer, Jelly style Jelly has compressed string literals, using the “...» delimiters. The way these work is by interpreting the ... as a base-250 integer, \$n\$, then repeatedly divmod-ing this integer until it reaches \$0 \newcommand{\d}[2]{ \left( \left\lfloor \frac {#1} {#2} \ri...

Output a random pair of twin primes. Every pair should possibly appear and the program should have zero possibility to fall into infinite loop. Notice that we don't know if there are infinite many pairs so you need some fallbacks to avoid finding a not-existing pair.

I am trying to achieve user defined number count click. The problem is, its keep prompting user, i want user to be promoted once only. Below is my code function clickCounter() { var person=prompt("Please enter your name","12"); if (person!=null) { ...

Added trailing whitespace code-golf Sometimes, we accidentally have trailing whitespace in test cases, and some helpful person notices and fixes that. Thank you, helpful people. But what if we want to take a string without trailing whitespace and add some? Your challenge is to write a program tha...

Parts Gets the user input. This part is a console without window. Generates Penrose polygon according number entered in the user input. The user input is number of sides in the Penrose polygon. For example, if user input equals 3, output is Penrose triangle. This part creates a window and it's G...

Minimally destroy CGCC in Game of Life Inspiration Conways' Game of Life is a well known cellular automaton "played" on an infinite grid, filled with cells that are either alive or dead. Once given an initial state, the board evolves according to rules indefinitely. Those rules are: Any live cel...

Is this an one-one function? code-golf, math, set-theory, function Two sets given as input, one is the domain of a function, and other one is the co-domain of a function. As an example $$ \{1,2,3,4\} $$ $$ \{5,6,7,8,9\} $$ Now if the range set of the function, i.e. set of each element in the co-...

In a 9 by 9 grid some points have been marked. The task is it to make a program that counts all distinct squares that can be made using four marked points. Note that squares can also be placed diagonally. Input can be one of the following: A character string of length 81 containing two distinct ...

What's missing code-golfstringdecision-problem Write a program which takes two arrays of strings as input. One of them (your choice which) will have one item missing compared to the other. Your program must figure out what is missing. Rules You can choose which array has one missing. The arrays m...

There is a well-known bijection between the permutations of \$n\$ elements and the numbers \$0\$ to \$n!-1\$ such that the lexicographic ordering of the permutations and the corresponding numbers is the same. For example, with \$n=3\$: 0 <-> (0, 1, 2) 1 <-> (0, 2, 1) 2 <-> (1, 0, 2) 3 <-> (1, 2, ...
