# Introduction
A swift implementation of concurrent (thread-safe) skip list.
This package is mostly based on [sean-public/fast-skiplist](https://github.com/sean-public/fast-skiplist).
## What is Skip List?
To simply put, skip list is a data structure to represent an ordered set.
This package provides API similar to swift's `Set`.
It is a probabilistic data structure and the average complexity of `search`, `insert` and `delete` are O(logn) respectively, while O(n) in worst cases.
| | Average | Worst case |
| - | - | - |
| Search | O(logn) | O(n) |
| Insert | O(logn) | O(n) |
| Delete | O(logn) | O(n) |
