Solution: All O`one Data Structure
Explore the implementation of the AllOne data structure that supports incrementing, decrementing, and retrieving max and min frequency keys in O(1) time. Understand how to combine hash maps with a doubly linked list to maintain frequency-based grouping, enabling efficient updates and queries for coding interview problems.
