Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

I think that this solution is the most interesting!
You made it in totaly different way than I did but it is interesting.
Very enjoyable series. It is very good that I could make a whole series of Kata's to train :)
Hi, this kata is quite simple but not very enjoyable. There are many metro stations to include and it iplicates rather long code. Two lines or 10 stations at each line would be sufficient IMHO. There could be good idea to provide 3 variables - one for each metro line.
There could be also a variant of this kata for stations where metro lines are crossing.
