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 could maybe simplify that a bit
Referactored the code to make a simplier and more concise solution that only shows to the end user the method instead of the whole class body. The class body is preloaded instead.
Here is a C++ tanslation of this kata.
One of the hardest kata I had faced, really entertaining and helpful, I had to explore tens of different approaches to finally have the solution. I really reccommend it.
This code wasn't meant to be published, I was testing performances between two algorithms...

Ok, everything is fine, I was wrong... I only realized now that you need to move using BFS in the tree.
Hi ! I am currently working on this very good exerccice. It is very engaging. But, I am struggling with the given example of a tree of height 3 where we search for the 3th node in pre order (3, 3). I do not find that the 3th node visited is 5 but 4 (even when doing the traversal by myself). So I wanted to know if I was wrong or if there was a problem in the example.
