One of my colleagues introduced me to Project Euler. From their website:
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.
I thought these were interesting problems, so I thought I would give them a go. Since PL/SQL is my language of choice, I figured I would see how many I could do using SQL or PL/SQL. I will post my solutions when I get time. I am no mathmatician, so there will likely be much more elegant ways to solve these problems, but I am always up for a challenge so it should still be fun. If you know of a better solution for any of them by all means let me know!
