Soenneker.Utils.Strings.HammingDistance

A utility library for comparing strings via the Hamming Distance algorithm

Installation

dotnet add package Soenneker.Utils.Strings.HammingDistance

Why Hamming Distance?

Hamming Distance is a simple yet powerful metric for comparing strings or sequences of equal length. It is especially useful in scenarios where exact alignment and positional differences matter, such as:

Positional Accuracy:

Hamming Distance identifies and quantifies differences at each specific position in two sequences.

Binary or Fixed-Length Data:

It is ideal for comparing fixed-length strings, binary data, or encoded sequences.

Lightweight and Efficient:

Hamming Distance has low computational overhead, making it well-suited for performance-critical applications.

Ideal for Error Detection:

It is commonly used in error detection and correction algorithms, like detecting bit-flip errors in transmitted data.

Usage

var text1 = "kitten";
var text2 = "sitten";

double similarityPercentage = HammingDistanceStringUtil.CalculatePercentage(text1, text2); // ~83.33

Note:

Hamming Distance requires strings of equal length. If the strings differ in length, an exception will be thrown to ensure valid comparisons.
