![### Understanding Balance Factors in Binary Trees - Educational Guide
#### What is the balance factor of the node of this tree labeled with the red triangle?
In this educational example, we address the evaluation of the balance factor within a binary tree structure. The tree depicted in the provided diagram has various nodes with values, connected via edges, forming a hierarchical structure and the balance factor is a crucial attribute of every node in this tree.
##### Explanation of the Binary Tree Diagram
1. **Nodes and Values**:
Each rectangle represents a node within the binary tree. The number inside the yellow section of each node represents its value.
For reference, the nodes and their values are:
- The root node has the value 14.
- Further nodes are connected hierarchically with values 17, 4, 15, 21, 19, 25, and so on.
2. **Edges and Connections**:
Black lines with arrows depict the parent-child relationships. Nodes have left and right children, connected down the hierarchy.
3. **Node Specifics**:
- The node labeled with a red triangle has the value **14**.
##### Determining the Balance Factor
The balance factor for any node in a binary tree is calculated using the formula:
\[ \text{Balance Factor} = \text{Height of Right Subtree} - \text{Height of Left Subtree} \]
To find the balance factor of the node labeled with the red triangle (node with value 14), let's determine the heights of its left and right subtrees.
- **Left Subtree of Node 14**:
- **Root Node**: 4
- Height Calculation:
- Node 4 has children 3 and 12.
- Node 3 has no children.
- Node 12 has children 9 and 15.
- Node 9 has children 7 and 11.
- Node 7 has one child, 10.
- Longest path: 4 → 12 → 9 → 7 → 10 (4 edges)
- Height = 4
- **Right Subtree of Node 14**:
- **Root Node**: 17
- Height Calculation:
- Node 17 has children 15 and 21
- Node 21 has children 19 and 25.
- Node 25 has one child, 24.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb04829d0-4645-426e-bf1a-7ada40b0786f%2Fda517347-155c-4488-8398-ebf1cfb0289c%2F0jrdo0f_processed.jpeg&w=3840&q=75)
