i believe that it checks every nodes height and makes sure that the left -right is 1 or 0 or -1. It is supposed to return tree if tree is balanced which means that left-right is 0 or 1 or -1 at every node. [CODE] template <class KT, class DT> …

Don't think you can pass any parameter unless you create a point in your main.

My understand is in generic programming you can have multiple containers, which use iterators but use the same algorithm. Wouldn't template be considered a ADT? Really confused.

I would say yes since both are ways of storing information.
