I found these challenges very useful to the development and assessment of my programming abilities. From now I I will post a question from the Project Euler website as a challenge to all readers who have an interest in programming. Ideally the solutions will be submitted in PHP, but other languages will be accepted. I will post a challenge every Monday to give you the week to work on it and from the order of the submitted solutions we will know who came up with the answer first.

What is 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.

The motivation for starting Project Euler, and its continuation, is to provide a platform for the inquiring mind to delve into unfamiliar areas and learn new concepts in a fun and recreational context.
