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.
hyper573's solution turbed out to be correct. I added a few test cases to weed out some incorrect solutions back in april.
@qgppl any update on when this will be fixed?

I have the same issue as thurstonzd. I've found the answer wanted, but still don't get why it's accepted.
For example:
"2018-09-11 07:17:57" - "2018-09-14 07:17:57""2018-09-12 07:17:57" - "2018-09-16 07:17:57"these visits do not overlap according to accepted conditions. Why?
sentenzo is right. Issue closed.
The best I could do without breaking all current solutions for SQL is adding a conditional comment to the SQL description. I hope that's enough.
The same problem I had.
You should remove spaces from your results.
This is what the output tries to tell you.

Hi! You are correct as far as general rule goes, but please take into account that the description mentions 'timestamps' i.e. dates with time of day. You may also encounter corner cases, when one event's start timestamp is equal to another one's end timestamp. Good luck!
I agree, spaces are counted as characters as well.
I'm also having a problem understanding the encoded message divvying up part of the Kata. I think the spec could have been made a little more clear or less complicated. I read that thing like 3 times and still don't quite get it but I'm gonna try out a few variations of my interpretation. lol
