Project Euler is a collection of math problems that people solve for fun. For each problem, you get a description and an input. Your job is to come up with the answer and submit it.
Important: You only have to submit the answer! So you have a lot of flexibility when solving a problem. Solve it by hand, on a calculator, with Wolfram Alpha, write a program, whatever -- as long as your answer is correct.
To prevent cheating (e.g. looking up the solution), Project Euler occasionally changes the input to their problems.
-
We need your help to solve as many problems as possible!
-
The list of problems is ever-growing as Project Euler is always adding new problems
-
When adding your solution here, make sure it's a method of finding the solution and not the solution itself
-
You can submit your solutions to previously solved problems, but don't ignore the unsolved ones :)
-
Visit http://brockcsc.github.io/project-euler for an overview of which problems have been solved
- Do not edit the work of others (such commits will be reverted)
- You can leave comments on commits to suggest improvements to solutions
- Do not submit solutions found by the work of others as your own (i.e. do not plagiarize)
- Follow naming conventions
- Solutions are named after the problem # and your username
E.g. My solution to problem #1 would be located at/project-euler/001/1-dideler.cpp
Example based on a command line interface (e.g. Bash on Linux, Git Bash on Windows, etc.) There are many ways to get started, this is one way:
$ git clone git@github.com:BrockCSC/project-euler.git
$ cd project-euler
$ git remote add upstream git://github.com/BrockCSC/project-euler.git
$ git fetch upstream
* Let's work on problem 10 *
$ mkdir 010 # Create the directory for problem 10 if it doesn't exist yet
$ cd 010
* Work on your solution. Go to the next step when you're done *
$ git add .
$ git commit -m 'Add my solution for problem 10'
$ git push # Your solution is now on GitHub!- Online Encyclopedia of Integer Sequences (find patterns in integer sequences)
- Wolfram Alpha (computational knowledge engine)
Challenge yourself in any way you like. Your solution can be:
- efficient or slow (there are no time constraints)
- long or short
- a dirty hack or the most elegant piece of code
- obfuscated code or coded using your favourite style guide
- crazily complex or super simple
- instructions for a person or instructions for a computer
- ... whatever!
No matter how you choose to solve a problem, try to have fun and learn something new 😉
