Programming exercises

Name: Anonymous 2008-10-13 13:28

So right now I have nothing I need to code for myself, or at least nothing I'd be ABLE to code for myself, but I still want to improve the quality of my code/get better/learn more.

Does anyone know of a website with programming exercises of beginner-intermediate level for Sepples and/or Java that would actually interest me?

I googled around a little and most of the exercises there were shitty university assignments.

Too hard for you? All programming-related things worth doing are maths challenges.

what knowledge are you lacking, OP?

For better sepples style, read anything by Herb Sutter you can get your hands on, starting with http://www.gotw.ca/publications/c++cs.htm

I haven't touched client-server stuff, socks, etc

As for the thread, thanks for spoj.pl, but like the other guy said, projecteuler is more about maths than it is about programming. Nothing really worthwhile to learn there.

Sign up and have a go at the problems there. Focus is on algorithms, which are a coder's bread and butter.

So, a little bit of network programming homework is required.

If you're happy with UI programming, then why not start off with a simple boardgame program -- this one might be fun to emulate : http://pentago.com/

So, in layman's terms:
The complexity of a problem is given as an order of an expression, it may be a polynomial, like O(x^2) and it's cool, but when the complexity is exponential, like O(2^n), it's not cool and the problem is NP-complete.

Did I get this right?

Project Euler is a great way to learn algorithms and maths.  On top of that, you see a lot of different implementations in the threads which can teach you a whole lot in many languages.

For NP-Complete problems it's not certain if they can be solved in polynomial or exponential time.

The time complexity of a decision problem is given as the time complexity of the best algorithm to solve it on a deterministic Touring machine. It is written as an order of an expression, e.g. O(x2).
If the expression is a polynomial, the problem is in P and often it's cool. When the expression is exponential, like in O(2x), it's almost always not cool and the problem is in EXPTIME.
If a problem can be solved in polynomial time on a nondeterministic Touring machine, it's in NP. If a problem in NP has the property that all other problems in NP can be Karp reduced to it, then it's in NP-complete. A consequence of this is that if one problem in NP-C is in P, every problem in NP is in P.

Currently, we know that P ⊆ NP ⊆ EXPTIME and that P ≠ EXPTIME. The million dollar question is whether P = NP, NP = EXPTIME or neither.
