Add index field to BinaryTree

I have a database table which has the specifications for a binary tree. See attached for pictures of sample binary trees.

I will share the database specification as well as code with the winning bidder. I have the tree defined in an SQL database (embedded Derby). The creates, updates, add, delete nodes as well as drawing of the tree have been implemented.

I have a field that I need to add to create an index in a particular way to this database. This project is just for adding of that field and the formula for it. I will share the formula with the winning bidder.

I will pay up to $50 for this.
