This is a reference collection, no build or install needed, browse markdown files and follow links to individual repos.
This repository collects community-submitted solutions to the programming challenges published on Coding Challenges (codingchallenges.fyi). The site publishes a series of hands-on projects where developers build working versions of real tools from scratch: things like a JSON parser, a web server, a Redis server, a load balancer, a shell, a DNS resolver, a Git client, and many others. The repository itself is organized around those challenges. Each challenge gets its own markdown file under a Solutions folder, and that file links to the different implementations people have submitted in whatever programming language they chose. There is no single language requirement, so you will find solutions written across many different languages depending on what each contributor used. The list of covered challenges is broad. It spans classic command-line tools (wc, cut, grep, cat, head, diff, sed, sort), network-level tools (load balancer, HTTP server, DNS resolver, traceroute, port scanner, SMTP server, DHCP client), data structure and algorithm projects (Huffman compression, Bloom filter spell checker, Lisp interpreter, Forth interpreter), games (Tetris, Pong, Chess, Snake, Minesweeper, Asteroids, Space Invaders), and server infrastructure projects (Memcached, NATS message broker, Bitcask storage engine, Docker). The range is deliberately wide so that developers at different skill levels can find something that matches their interests. Adding a solution follows the standard open-source contribution pattern: fork the repository, create a branch with your changes, push it to your fork, and open a pull request. The project has a Discord community for discussion. No specific language or framework is required to contribute.
