## Overview

This repository is a collection of independent solutions to coding challenges, not a single application or shared execution framework. The principal workflow is to choose a challenge, provide its expected input or use its example input, and run or submit that solution to obtain an answer. The README names Codewars, Kattis, and LeetCode; the tree also contains other challenge collections. Sampled programs show varied input and output patterns, so the graph groups solutions by collection rather than implying shared runtime wiring. Unsampled solutions are represented only at their enclosing directories.

Main entry points: [`CodeWars/cpp`](https://github.com/jonasjore/coding-challenges/tree/master/CodeWars/cpp) (C++ katas), [`CodeWars/go`](https://github.com/jonasjore/coding-challenges/tree/master/CodeWars/go) (Go katas), [`CodeWars/java`](https://github.com/jonasjore/coding-challenges/tree/master/CodeWars/java) (Java katas), [`CodeWars/javascript`](https://github.com/jonasjore/coding-challenges/tree/master/CodeWars/javascript) (JavaScript katas)
