I have completed nearly fifty of the practice problems on Project Euler, but I would like to move away from the pure mathematics, number theory, and programming practice problems for a bit and solve more practical mathematics problems for preparation of my future major (physics). However, I appreciate Project Euler's mechanism of presenting a problem and offering a PDF document with the solution only after the answer has been found.

Does something similar to this application exist?

Sphere Online Judge is a great site filled with loads of programming puzzles


There are programming challenges - sites. Look at these listed up in:

Happy coding :-)

  • All these are nice sites, especially Programming Praxis and Code Chef, but I would like to lean toward mathematics-based practice sites instead of strictly programming and bit logic. I have tried searching Google for "mathematics practice problems" and "mathematics challenges" but have only found a single site that offers problems at a higher level than high school calculus. – Vortico Jan 24 '11 at 23:45
