Subject: Information Technology/Computer Science Java Programming Language: 1. Create a class that accepts id numbers ranging from 1 to 29. 2. The id numbers are nodes of a binary tree. 3. Traverse the tree in inorder, preorder, and postorder and display the traversed values.
Build an AVL tree by inserting the following sequence in order: 1 9 6 7 11 12 A NULL node can be indicated by the symbol 0 (ZERO).

Let R be a binary tree of integers without repetition, (each node contains a value whole), it is assumed that the tree is already created. Write an algorithm that allows to: 1) Calculate and display the product of the values stored in the nodes of the tree R, (if the tree is empty the algorithm must display the zero). 2) Calculate and display the depth of the node which contains a given value (V), (if the tree is empty, or (V) does not exist, the algorithm must display (-1)).
