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.
but anyway, as far as I remember, there is no such testcase at all...
It's as Galmieux said, that should be
EE
notE E
I suppose it's doesn't metter, since trailing spaces shoud be completely ignored
Isn't the output for that should be just EE, since only 1 space between those dots instead of 3
I suggest test:
. .
should beE E
(i.e. some more trailing whitespaces at the end of input)
