For learners of ruby

Recently , an organization was created on github - Habraruby (it still includes 2 people, I hope that this number will grow significantly). Initially, she owned one repository with tasks from the site acm.mipt.ru. But in view of the fact that there are few critical people, and the tasks themselves are non-trivial, I decided to open another repository with tasks from the site spoj.pl

Firstly, unlike MIPT tasks (of which there are about 400, if I’m not mistaken), there are more than 9 thousand tasks on the spoj. It is not necessary, probably, to say that the level of many of them is acceptable for beginners. True, the conditions in English, but I think that it does not matter.

I’ll repeat what all this is for — for those who are just starting to learn Ruby, or just become familiar with the syntax, it is often necessary to read simple code. Usually, all available Ruby sources are related to RoR and are useless for beginners. And just in the role of such a base, the repository will serve as a simple code for understanding.
For the venerable rubists, this is just a chance to share experience and maybe learn something new even for themselves. In any case, everyone can find something for themselves.
