什么是 Codend？

Codend is a structured academy for learning CS the way a degree teaches it from first principles, not tutorial-hopping. Full courses on Algorithms, Computer Architecture, Networks, Databases, Operating Systems, and Design Patterns and more courses, built for real depth. Plus daily coding challenges with streaks and XP to keep you sharp. Subscribe for full access. Built for devs who want the "why," not just the "how."
