Dear Colleagues,

I would like to bring your attention to Codility Training Site (

It is addressed to both, advanced programmers that train and take part in various programming contests, and those that learn basic programming techniques.

Contestants can find a collection of 30+ (and growing) challenging programming tasks together with a discussion of possible solutions.

Less advanced students can find over a dozen (and growing) lessons covering basic programming techniques together with 30+ exercises.

All the tasks can be solved in 14 programming languages, and the solutions are assessed on-line in the IOI style.
