We create another BinaryTree as shown below:

BinaryTree animals $=$ new EmptyBinarySearchTree$()$;

BinaryTree names;

BinaryTree people $=$ new EmptyBinarySearchTree$()$;

people $=$ people.add$("$bat$")$;

people $=$ people.add$("$rat$")$;

people $=$ people.add$("$mouse$")$;

people $=$ people.remove$("$bat$")$;

Show an object diagram for each of the variables names, people, and animals, after this code has executed. In an Object Diagram:

If the variable is a primitive type, show its value in an oval, right next to its name $($Strings and wrapper classes may be treated as primitives, to simplify the diagram$)$

If the variable is an object type, show its value in an oval next to its name, as an arrow $($i$.$e$.$ a reference$)$ to an object, shown in a rectangle. The object should include:

The name of its class at the top $($e$.$g$.$ Student, BST$,...)$ at the top

The name of each instance variable $($i$.$e$.$ non$-$static field$),$ with its value in an oval.

Note: Strings and wrapper classes may be treated the same as primitives.
