written in Ruby on Rails by Mek…
It took me a whole day to write this, i thought it was small and would be fast but I was wrong Maybe because I’m just a beginner in rails or Critical in many parts.
To run the app: of course set it up on rails set up the db too,
open in two different browser or computer because it uses session params
there maybe a lot of bugs, I don’t know, i didn’t test..
the code is not clean, i write it while designing the algorithm
