Amigo, it seems you may now have an adequate foundation. It's time to test your skills by doing a big task!
Today, we'll implement our own tree in a slightly non-standard way (based on AbstractList).
To get background information, use your favorite search engine and the text below.
The nodes of the tree should be like those in the picture:
First, let's make our tree a descendant of the AbstractList class with a String parameter, and we'll implement the Cloneable and Serializable interfaces.
For now, leave the standard implementations of the get(int index) and size() methods.
Requirements:
- The CustomTree class must support the Cloneable interface.
- The CustomTree class must support the Serializable interface.
- The CustomTree class must be a descendant of the AbstractList<String> class.

import java.util.List;
public class Solution {
public static void main(String[] args) {
List<String> list = new CustomTree();
}
