Solution: All O`one Data Structure

Explore how to design and implement the AllOne data structure that tracks string key frequencies with constant time complexity operations. Learn to use doubly linked lists combined with hash maps to efficiently update counts, retrieve max and min keys, and maintain data integrity under various operations.

We'll cover the following...

Statement

Design a data structure that tracks the frequency of string keys and allows for efficient updates and queries.

Implement the AllOne class with these methods:

  • Constructor: Initializes the data structure.

  • inc(String key): Increases the count of the given key by 11 ...
