# 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) |
