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.

random tests fail. I don't understand I return exacly the message required by ID. and yet expected is som erandomly chosen value? can you descrive what you expect in random tests? tacked my brain for half a day already. thanks. adding this to description would also help.
Although the tree traversal meant to be used here is not inherently a BST property, its output is, which is the key to the solution.
what is incorrect? can you elaborate?
Incorrect.
this is not a BST problem. it is a general BT problem. why put a misleading title?
This is not a kata issue. And we can't change the rank. I agree 7kyu seems too low for this one.
this kata is not for 7 kyu. I spend couple of days just digging into prime numbers theory to find a suitable alogorithm. compared to other 7 kyu kata this was hard! it is 6 kyu may be?
