algorithm - Number of nodes in the bottom level of a balanced binary tree -


i wondering 2 questions came when studying binary search trees. following:

what maximum number of nodes in bottom level of balanced binary search tree n nodes?

what minimum number of nodes in bottom level of balanced binary search tree n nodes?

i cannot find formulas in textbook regarding this. there way answers these questions? please let me know.

assuming it's full binary tree, number of nodes in leaf equal (n/2)+1.

for minimum number of nodes, total number of nodes 1 (satisfying condition should balanced tree).

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
