For an anti-plagiarism application I developed about a year ago, I needed a way to calculate the similarity between two strings. I wasn’t sure how to go about doing this at first, but then I came across the Levenshtein Distance Algorithm which gets the job done well. In this example, I’ll show you my Distance class implementing the Levenshtein Distance Algorithm, and how to use it to compare strings (specifically the minimum distance between two strings needed to make them equal). This is also very useful for determining how similar (or dissimilar) two strings are.
