Mastering Skip List Implementation in Python with Examples

Skip lists are a fascinating data structure that offer an efficient way to store and retrieve data. If you are a Python programmer looking to expand your toolkit, understanding skip lists can be incredibly beneficial. Here, we will dive into the skip list implementation in Python, breaking down its algorithm and providing practical examples.

What is a Skip List?

A skip list is a type of data structure that allows for fast search within an ordered sequence of elements. It achieves this by maintaining multiple layers of linked lists, where each layer skips over a fixed number of elements, thus reducing the time complexity of search operations to O(log n).

Skip List Algorithm in Python

Before we jump into the code, let's understand how the skip list algorithm works:

Insertion: Insert elements in the base linked list, followed by the higher levels. The position in the higher levels is determined probabilistically.

Search: Start at the highest level and move forward. If you overshoot, drop down a level and continue.

Deletion: Similar to insertion, but involves removing elements from different levels.

These operations make skip lists an attractive alternative to balanced trees like AVL or Red-Black trees, especially when probabilistic balance is acceptable.

Node Class
To start with, we first need a Node class to represent each element in our skip list.
