Thanks, Natalia, for your detail explanation.  If I understand it right, we
use variable Var to point to the portion of the tree that we want to keep
and build the new tree with new node B and Var.  Question: Do we create a
duplicate tree and delete the old one or just switch the pointers around?

Thanks again.

Tak
