Solution: All O`one Data Structure
Explore how to create the AllOne data structure by combining a doubly linked list and hash maps to track string key frequencies efficiently. Understand how to perform increment, decrement, getMaxKey, and getMinKey operations all in average constant time, enabling effective frequency management with 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
