online judge sites

[Erik Rantapaa]

Hi everyone,

At the meeting I mentioned that there were a couple of "online judging" sites which support Haskell. They are:

  - codeforces.com

  - acm.timus.ru

I've compiled a list of all of the problems on codeforces.com which have Haskell solutions:

You can use the "Status filter" to filter submissions by a particular language and then from there view individual submissions.

Here is a selection of problems on coderforces.com that people might enjoy solving. They are all "elementary" in that they don' require you to solve some hard mathematical problem first:

http://codeforces.com/problemset/problem/44/A

  - Indian Summer

http://codeforces.com/problemset/problem/20/A

  - BeOS File System

http://codeforces.com/problemset/problem/8/A

  - Train and Peter

http://codeforces.com/problemset/problem/2/A

  - Winner

http://codeforces.com/problemset/problem/384/A

  - Coder

http://codeforces.com/problemset/problem/387/A

  - George and Sleep

http://codeforces.com/problemset/problem/14/A

  - Letter

  - T-primes

And some more advanced problems:
