Hints

1. Define the GbTree external type

• External types can be defined using the pub type TypeName(a, b, c) syntax.

2. Define the new_gb_tree function

• External functions can be defined using the @external(erlang, "module", "function") syntax.
• The function should use the gb_trees:empty/0.

3. Define the insert function

• Check the gb_trees:insert/3 documentation to confirm the correct order of arguments.
• The external function can be a private function that is called by the insert function in order to change the order of the arguments.
• The function should use the gb_trees:insert/3.

4. Define the delete function

• Check the gb_trees:delete_any/2 documentation to confirm the correct order of arguments.
• The external function can be a private function that is called by the delete function in order to change the order of the arguments.
• The function should use the gb_trees:delete_any/2.
• The gb_trees:delete/2 function will crash if the key is not found, so it should not be used.
