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.

Phew!!! What an amazing kata! really thorough and illuminating test cases too. The Track parsing was insane
Is this an example I should be worrying about or is it illegal?
The reason I ask is that the diagonal lines are technically crossing but a train could never occupy the same point in space while inside this crossing which makes it quite a challenge to consider if they have crashed.
Interesting challenge, I tried a lot of approaches and failed alot before getting a solution that didn't time out. Would it be possible to leave the expected time and space complexity in the Kata description to make it clearer when beginning the Kata what is expected? Also, it is not obvious how high the random tests go but in python I pass the random tests as long as the tests dont go higher than node len(16500) which is not clear to me if I have a) actually beat the challenge and it's not optimised for python or b) lucked out with the random tests and didn't really beat it
Not sure if negative indexing is meant to be illegal for the pagination helper class, not mentioned in the description however given the tests include negative indexing this should probably be specified.
