Few if any names hold as much weight in computer science as Donald Knuth. So when knuth proposes a solution to a problem, you'd be wise to listen. Amongst his (many) famous contributions is the awesomely named "Algorithm X". To quote wikipedia, Algorit

A fundamental concept for software engineers when it comes to writing maintainable software is the DRY principle: Don't repeat yourself. Many times when writing code we may find ourselves implementing algorithms that are very similar in structure to ea

The set ADT is an important and unique (see what I did there?) data structure with many uses, and many ways to implement them. Often implemented over a linked structure, sets are not quite a list and not quite a dictionary, but often have similar funct

When implementing data structures, its crucial to validate that your implementation is working as expected. A suite of tests is essential to not only debugging, but also optimizing performance one your implementation is correct. In the past I've discus
