What is a skiplist and What are skip lists used for?
Skip Lists: A Faster Alternative to Linked Lists & Balanced Trees
Skip Lists are a probabilistic data structure that enhances the efficiency of linked lists by allowing faster search, insertion, and deletion operations. They achieve this by maintaining multiple layers of linked lists, where higher layers act as "express lanes" to skip over multiple elements, reducing search time.

Why Databases Use Skip Lists? 🔥
Fast Indexing – Used in in-memory databases like Redis for ordered sets.
Lightweight Alternative to B-Trees – Simpler to implement with similar efficiency.
Concurrency Friendly – Works well in multi-threaded environments.

I love the skip list conceptually. It's so fascinating that you can use randomness to make something that's in principle deterministic more efficient.
