can anyone give me a hint about this problem
I found the help for this problem to be a bit circular. In the end, there was a comment from one of the blog posts that mentioned looking at the undocumented mtree code (e.g. 'edit mtree' a the command line). It's a big class, but try looking for the nodesize method and go from there. I don't know if this is how actually how cody comes up with the score, but the number of nodes from mtree works as a solution here.
