How to painlessly implement an associative array using a hash table.

Hash Tables

When it comes to the literature Hash Tables are often glossed over. Data Structures and Algorithms(DSA) books tend to focus on more complicated,

Exploring the 'Skip List' data structure as an alternative to self balancing Binary Search Trees for key/value pairs

What's a 'Skip List'?

A skip list is a data structure that was developed due to some of the 'unpleasant' asp

In this article I show how to implement Dijkstra's algorithm to show the shortest route by train through several American cities.

Sorting: Faster is Better

Tree sort is one of the less discussed sorting algorithms. The three elementary sorting Algorithms bubble sort, insertion sort, and selection sort are all worst case quadratic time algorithms.

A look at the three most common elementary sorting algorithms using perl

The First Three

When learning about sorting algorithms, or whenever one talks about sorting algorithms, there are three elementary sorting algorithms th
