# skiplist

![](https://upload.wikimedia.org/wikipedia/commons/8/86/Skip_list.svg)

Skip lists were first described in 1989 by William Pugh.

It is a probabilistic data structure that allows `O(log n)` search complexity as well as `O(log n)` insertion complexity within an ordered sequence of `n` elements.

> Skip lists are a probabilistic data structure that seem likely to supplant balanced trees as the implementation method of choice for many applications. Skip list algorithms have the same asymptotic expected time bounds as balanced trees and are simpler, faster and use less space.
