Solution: All O`one Data Structure
Explore how to design and implement the AllOne data structure that tracks string key frequencies. Understand how to use a doubly linked list and hash maps to support incrementing, decrementing, and retrieving keys with max or min counts all in constant time, optimizing frequency tracking in custom data structures.

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
