## Code design ### Adhere to ES6 standard naming conventions for APIs. Standardize API conventions by using 'add' and 'delete' for element manipulation methods in all data structures. Opt for concise and clear method names, avoiding excessive length while ensuring explicit intent. ### Object-oriented programming(OOP) By strictly adhering to object-oriented design (BinaryTree -> BST -> AVLTree -> TreeMultimap), you can seamlessly inherit the existing data structures to implement the customized ones you need. Object-oriented design stands as the optimal approach to data structure design. ## Benchmark [//]: # (Start of Replace Section)
