Project Euler
▁ feb 27 2008
Tired of writing code that moves data back and forth between web pages? Why not try Project Euler?
Project Euler is a series of challenging mathematical/computer programming problems that will require more than just mathematical insights to solve. Although mathematics will help you arrive at elegant and efficient methods, the use of a computer and programming skills will be required to solve most problems.
So far I’ve solved 4 out of 183 problems, and I’m just getting started. Our brains need exercise, and this is seems like a great way to get it.
The site also has forums that are unlocked when you solve a problem, and various statistics on users and programming languages.
Good luck!
