what is katas fr?

This is a personal collection of programming challenge solutions written in Scala. The repository contains the author's answers to "code katas", short, focused coding exercises designed to build programming skills through repetition and problem-solving. The repo itself is straightforward: it's a working directory where someone has solved various coding puzzles and saved their Scala implementations. Code katas are often drawn from sites like Codewars or LeetCode, or from coding interview prep materials. They typically range from simple algorithmic problems (like sorting or string manipulation) to more complex data structure challenges. By solving many katas, programmers practice syntax, logic, and problem-solving patterns in a low-stakes environment. This type of repository is useful for a few different audiences. A learner using Scala could browse these solutions to see how experienced developers approach common problems in that language. Someone preparing for a technical interview might use it as a reference to study solution patterns. Even experienced developers sometimes keep personal kata collections as a way to stay sharp or explore a new programming language they're learning. In this case, since it's marked as a personal project with only 6 stars, it's primarily the author's own learning and practice log that they've made public. The README is minimal, which is typical for personal practice repositories, there's no installation guide or detailed instructions because the main purpose is the code itself, not a finished product or library for others to use. If you're interested in seeing Scala code in action or want examples of how to solve algorithmic problems in that language, this could be a helpful reference point.
