The Euler Project

If you're tired of the endless stream of WAs and TLEs or you find yourself reading problem descriptions over and over again, without any increase in comprehension, it sure is time for some R&R. May I then recommend 'Project Euler' which can be found at http://mathschallenge.net.

It is a nice set of (currently 100) challenges mostly mathematical in nature that require moderate programming skills to solve. A lot of fun and highly addictive. Be warned

Thanks for posting this link! You were right, it's highly addictive

. The last couple of days I've enjoyed solving problems from this site. I found this an excellent way to train myself in number theory, as I'm somewhat weak in this area.

I liked the submission system a lot, including the fact that I don't have to worry about TLE at all (unless the programs need days to finish...) and the freedom to choose the tool I want to solve the problems.

<BUMP>
I like to bring this site under your attention again. It has now 125 problems and it is a great way to train your mathematical skills (which are essential if you want to become a good programmer).

Interesting site.

Seems like many of my problems are more suitable to that site than UVA

<BUMP AGAIN>
The current problem count is 156, and the latest additions are getting increasingly difficult. Project Euler now has its own website http://www.projecteuler.net.

Enjoy!

I've forgotten what is the closed form of a series like the one follows..

1.2 + 2.3 + 3.4 + 4.5 + ........................ + (n-1).n === ???

pls help

What do you mean by "(n-1).n"? When n is 10, it's 9.1 or 10?

zobayer · Post by **zobayer** » Tue Apr 14, 2009 11:22 am

when n = 10 its 9 x 10
sorry I used dots for multiplication notations

Just compute values of that sum for first few N and look them up in OEIS.
