Codewars is an online educational platform for computer programming. On the platform, users known as code warriors attempt to solve programming challenges, known as kata, to practice programming skills and earn honor points. Each kata is assigned a kyΕ« rank based on its subject and difficulty. The more difficult the kata, the more points will be awarded. All code warriors start at 8 kyΕ« π and advance through the ranks to the final 4th dan π₯. Warriors are not the ones who always win, but the ones that always fight. Banzai!
The repository contains a collection of Java solutions to Codewars challenges, grouped by kyΕ« rank. Each kata is organized in a separate folder named by its slug and accompanied by a task description, a solution source code, and verification tests. All solutions were solved on the official platform and verified against the original test suite.
For quick access, use the index table or search the repository by kata URL, name, ID, or slug.
