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.

ATTENTION : Please do not copy and paste solution directly! Actually, I don't want anyone refer to code for solution. You can take a look if you want to know what Project Euler looks like.

We hope that you enjoyed solving this problem. Please do not deprive others of going through the same process by publishing your solution outside Project Euler.
