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.
You're welcome ;)
The author is missing, so you have to wait for a power user to solve it in Ruby first and then review and approve your translation.
And what is the "other environment"? ;-) When you raise an issue you need to give the details, or how do you expect others to look into it? We can't read your mind.
The time spent by a blank submit is not the time it takes for the reference solution to run the tests because you also have to take account for the time to generate random test cases. When the test case size is large this is actually a very heavy operation (at least O(n)).
But in any case, since the kata needs to be published with a working author solution it can be passed. "I can't pass the tests" is not a valid ground for an issue, but instead a question ;-)
What's the problem with 700ms? That leaves you with 11300ms to spare, so your code can even be 15 times slower than the reference solution.
Your code is too slow.
