The goal of this project is to translate the wonderful resourcehttps://e-maxx.ru/algo which provides descriptions of many algorithmsand data structures especially popular in field of competitive programming.Moreover we want to improve the collected knowledge by extending the articlesand adding new articles to the collection.

We're an ad-free, volunteer-run website that's free for everyone. Users can contribute articles or help sponsor bounties on articles for greater algorithmic coverage. Your help is greatly appreciated.

Compiled pages are published athttps://cp-algorithms.com/.
