+# 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.
