### Understanding Binary Search Trees (BST) 

#### Example Problem:
Given the BST (Binary Search Tree) tree below, fill in the values in the table. 

#### Visual Diagram:
The diagram shows a BST with nodes represented by circular shapes with numerical values assigned to them. The tree starts with the root node 0034 and branches out through a hierarchy of nodes.

- The root node is 0034.
- Nodes descend from the root with connections established by lines indicating left (lesser value) and right (greater value):
  - The left subtree of the root contains nodes: 0005, 0045, etc.
  - The right subtree of the root contains nodes: 0067, 0098, etc.

#### Nodes in the BST:
- **Root Node**: 0034
- **Subtrees and Descendants**:
  - Left Subtree of 0034: 0005, 0017, 0021, 0002, 0050, 0040, 0045, 0043, 0055, 0049, etc.
  - Right Subtree of 0034: 0067, 0098, 0076, 0071, 0092, 0087, 0078, 0084, etc.

#### Properties and Values Table:
This table is designed to be completed using the provided BST diagram. Below are the properties that need to be determined:

| Property                                  | Value                  |
|-------------------------------------------|------------------------|
| Height of tree                            |                        |
| Height of node 45                         |                        |
| Depth of node 17                          |                        |
| Node 76 degree                            |                        |
| Tree degree                               |                        |
| Name the nodes in left subtree of node 98 |                        |
| Order of tree                             |                        |
| Internal path length                      |                        |
| External path length                      |                        |

#### Explanation of Each Property:
- **Height of Tree**: The maximum depth or distance from the root node to the furthest leaf node.
- **Height of Node 45**: The distance from node 0045 to its furthest leaf node.
- **Depth of Node 17**: The distance from the root node 0034 to node 0017.
- **Node 76 Degree**: The number of children linked to node 0076.
- **Tree Degree**: The maximum number of
