### Understanding Binary Trees and AVL Trees

**3. Binary Trees**

Binary trees are structured as follows:

```java
public class BTNode<E> {
    private E data;
    private BTNode<E> left, right;
}
```

In this context, a binary tree `t1` is considered a prefix of another binary tree `t2` if `t2` can be transformed into `t1` by removing zero or more leaves from `t2`. To implement this, write a method:

```java
public static boolean prefix(BTNode<Integer> t1, BTNode<Integer> t2)
```

This method should determine if `t1` is indeed a prefix of `t2`.

**4. Node Depth in Binary Search Trees**

The depth of a node is defined as the length of the unique path from the root to that specific node. For a full binary search tree with a height `h` and `N = 2^(h+1) - 1` nodes, you are tasked with finding the average depth of all `N` nodes.

**5. AVL Tree Insertions and Deletions**

Illustrate the process of inserting elements `9, 1, 2, 8, 10, 5, 4, 3, 7, 6` into an initially empty AVL tree. Following the insertions, if the root is deleted, it should be replaced by the smallest key in the right subtree. Visualize the AVL tree after each insertion, deletion, and rotation with an indication of the type of each rotation.
