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.
Good question. I am struggling also with the node check.
Per the description:
This isn't a bug. You're not passing because you're breaking the tests, you're passing because the operation you're doing in your solution is a valid way to recolor all the nodes. It's not one that I like, but it's valid, and trivializes the issue.
Perhaps the problem should force certain nodes to start as certain colors, in order to disable this trick? If so, that should be a separate kata. I'm certainly not coding it up here.
Regeardless, nice solution. Resolving.
Now deepcopying inputs prior to administrating tests, so mutation doesn't affect validation. Ty for callout.

Sample tests are also broken:
The kata needs to specify
len(paints)
, because this is relevant to the runtime complexity of the solutions too.This comment is hidden because it contains spoiler information about the solution

Amazing Kata, thanks for a something closely related to the real world problems.
Thank you for your kind compliment. I try.
This is really great @ALowVerus, thanks for leaving all your work and comments - I wish more people did it as it's a useful learning resource!
thanks <3
also nice job my guy :-D
Alright, so I has been solving this kata for the huge amount of time, and all this time I had the error when I misunderstood one of the imporant aspects lol. Because of that, I spent about... 3 months on this kata, even though I was really close to the right answer? But still, I had a university study, and that error was completely on my side :s
Apart of that, this kata is really good, I wish the issues with it would be cleared soon and it would get out of Beta :D
All the coins have to meet on the same vertex, not just two of them. u1 and u2 can stay together since they start on the same vertex but they need to meet up with u3.
