Warning

This repository is still a work in progress: links may not work, exercises may be missing or still not resolved, etc.
If you have particular requests (eg. you want an exercise to be resolved soon, can't find anymore a file, link broken), please open an issue!

This repository is an adaptation of the exercises provided in nbicocchi/java-core for Kotlin programming language.
I've made this repo mainly for making practice in Kotlin language. Feel free to comment my work by opening GitHub issues! Any help is accepted!
