Ruby problem solving Skills

Hi ,

Is there any interesting sites is available for problems solving in Ruby like Ruby-Monk.

So that we will learn things like
-> Data-structure like trees , graphs , stacks , linked list etc.
-> Design pattens.

Thanks,

Check out Ruby Koans, at http://rubykoans.com/.

the koans are a very cool idea and many people recommend it.

however, i went through the koans early in my ruby days and didn’t feel like i learned much. or i guess a more accurate description is - the stuff i learned didn’t stick with me for very long.

maybe it just didn’t fit my learning style or something.

at any rate, a similar site is http://rubeque.com/
