Solution: All O`one Data Structure
Explore how to design the AllOne data structure that tracks string key frequencies and enables O(1) time complexity for incrementing, decrementing, and retrieving keys with maximum or minimum counts. Understand the combination of hash maps and a doubly linked list to manage frequency nodes efficiently.

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
