Project 2: Implement an electronic dictionary system where users can store and retrieve items, e.g., books, by their keys. The data structures like lists, stacks, and binary search trees, etc, can be applied to different scenarios. You should firstly design the interfaces that you want to implement and choose the appropriate data structures to help you fulfill the tasks. Though the topic is given, many open issues could be discovered and solved. Project 2: Implement an electronic dictionary system where users can store and retrieve items, e.g., books, by their keys.
