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'm intrigued by this one, it's been biting at me for a while. I would probably have to get rid of the recursion to avoid a timeout.
I am sure you were jumping like crazy after it passed all the random tests :)
I think it took me a week.
If 's' is an empty string, 'o' and 'x' won't present, therefore it returns True as mentioned in the description's tests. When you count over an empty string you get zero for any value you are counting for.

Even after 4 years only 10 people managed to solve it. Remarkable!
How long did it take u to finish this honestly?
I will if I couldn't do any better.
Ok. But you can always skip the Python version and see how others have solved it.
It is my fault. My python code needs optimization. The tests took about 570-680 ms, but the random tests timed out. At least I had the chance to solve it in C++ ! Great Kata. Thanks!
Missing your point here. The python ref solution runs 660ms. Yours?
Timed out in Python, done in C++ :). Someone needs to optmize his code!
Take some more time and implement a relatively efficient algorithm.
