Welcome to GitHub's largest open-source algorithm library
We are a group of programmers helping each other to build new things, whether it be writing
complex encryption programs, or simple ciphers. Our goal is to work together to document and
model beautiful, helpful and interesting algorithms using code. We are an open-source community -
anyone can contribute. We check each other's work, communicate and collaborate to solve
problems. We strive to be welcoming, respectful, yet make sure that our code follows the latest
What is an algorithm?
An algorithm is a set of rules that takes in one or more inputs, then performs inner calculations
and data manipulations and returns an output or a set of outputs. In short, algorithms make life
easy. From complex data manipulations and hashes, to simple arithmetic, algorithms follow
a set of steps to produce a useful result. One example of an algorithm would be a simple function
that takes two input values, adds them together and returns their sum.
We support many programming languages. Each language has its own GitHub repository where all the
code for the algorithms is stored. Here is a list of the current programming languages:
We encourage you to contribute to these repositories. If you have an algorithm
that you want to add, a change you want to make or a bug you want to fix, please
do so. But before you do, make sure you have read the contributing
guidelines found in CONTRIBUTING.md in the repository. Make sure
that you are respectful, helpful and using the latest version of the language.
After reading the contribution guidelines, please fork the repository, work on
your changes and then submit them as a pull request.
