In the game 2048, you have a grid, and you can move the elements in four directions. They all move in that direction as far as they can. For this challenge, you will be given a padded, square 2D string (either with newlines, or a list of strings), like so: ab cd e f ghij kl mno p q ...

I have a new idea for code-golf challenges, scored code golf would be used for multi part challenges that correspond and the score adds up. This would allow for linking different challenge types together. I need help knowing if this is a good/bad idea and ideas for rules. The real problem is you...

Meta-background This was set as a question on Puzzling, and the instant reaction was "well, someone will just solve that by computer". There was a debate about just how complex a program to solve this would have to be. Well, "how complex does this program have to be" is pretty much the definitio...

Most of us, I'm sure, come to this site either to solve delightfully tricky programming puzzles, or to see what insane golfs other members of our community have written. However, now we ackgnowledge the creative brilliance of those that come here to write those challenges that we've collectivel...

Given a string of digits or an integer as input, you will have to indexize it. This is how you modify the input. We will use 30043376111 as an example: First, find sum the indices of each occurrence of the respective digits: 0: 1 + 2 = 3 1: 8 + 9 + 10 = 27 3: 0 + 4 + 5 = 9 4: 3 6: 7 7: 6 T...

Background By expanding and cancelling terms, it is easy to show the following identity: However, it is an open problem whether all 1/n-by-1/(n+1) rectangles can tile the unit square. The Task Your program should take a positive integer N as input in any convenient manner, and pack all 1/n-...

This challenge is inspired by Robert Frost's famous poem: The road not taken Two roads diverged in a yellow wood, And sorry I could not travel both And be one traveler, long I stood And looked down one as far as I could To where it bent in the undergrowth; Then took the other, as just as fair,...

Concatenate Numbers! So Exciting! Your task: given an integer n output all the numbers up to n concatenated into a single number. But you need to do that for every number up to n as well. Concatenation: sticking digits together. For example, the numbers 1 and 1 concatenated would be 11. Stand...

The Program You are given two strings, A and B. A is the current position at which your timer is at, and B is the position at which your timer will stop. Both strings are in the format m:ss. You must write a program that determines the amount of time left which should also be formatted in m:ss. ...

Golf an Ungolfer! Your task: given golfed code of a specified language, ungolf it. Input and output should be as a string, through the standard methods. For example, if a program were given the C++ code: #include <iostream> int main(){std::cout<<"Hello World!";} It might output: #include <...
