This question evaluates data modeling with enums, efficient data structure selection to meet specified time complexities, API design for CRUD operations, and practical implementation skills including a command-line interface and unit testing.

Design and implement a console-based restaurant menu management program. Requirements: (

  1. There are exactly three fixed item categories represented by an enum (e.g., APPETIZER, MAIN, DESSERT). (
  2. Support addItem(name, price, category), updatePrice(name, newPrice), removeItem(name), listAll(), and listByCategory(category). (
  3. Print items using each object's toString() rather than accessing fields via getters; list output grouped by category and sorted alphabetically within each category. (
  4. Choose data structures to achieve O(
  5. add/update/remove by name and O(k log k) listing within a category (k = number of items in that category). (
  6. Provide a simple CLI that reads commands from stdin and executes them, plus basic unit tests.
