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.
Get started now by creating a new collection.
i hate this task, because i cant get through tests just ive used "to_char" function in postgre with '0.999' pattern...
Table wa just as in the result, but tests throwed exceptions like '_0.234 ---> 0.234 expected'
i guess its too easy...but i learned about 2 new postgre functions for me!)
