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 looooove such explained answers. Keep 'em coming. Thanks.
Makes alot of sense to me, well done!
It is not.
Why return 0 is needed at the end?
This one is just very simple and useful. Nice
This is my favorite solution
Agree, this is horribly worded. I thought we had to find common characters in both strings and then remove duplicates.
I believe you are to combine two strings into one, remove any duplicate letters, sort the string in alphabetical order, and return the largest possible string that has all unique characters.
If i see this in production I comment and do it again ¬¬
I do not understood what I have to do. This description is so confuse...Anyone can help?
