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.
so what was it?
That's a subsequece, not a substring.
One isn't allowed to skip characters when chosing substrings.
"substring('abcba') should return 'bcb'" this is wrong. "abba" use only 2 chars and got 4 long string.
hihi, nice one :)
Wow, way to cheat the test cases...
Ok, found myself the problem, fixed :)
Im having problems with the third "online" test. sum values that are numbers and are between the minimum and maximum.
After a lot of time learning how this works, i finally managed to get everthing in place, but in the third test the filter decorator is nowhere to be found. Is like if the test dont have that filter, hopping for the program to remember from the second test???
