Solution: All O`one Data Structure
Discover how to design and implement the AllOne data structure using a doubly linked list and hash maps to track string key frequencies efficiently. Learn to perform increment, decrement, and retrieve max or min key operations in constant time, enabling you to solve complex interview problems involving custom data structures.
