About the repository

This repository contains my solutions for questions from the book "Cracking the coding interview: 189 Programming Questions and Solutions", the website Codility and another sources.

Some of my solutions are complete, others are still in progress. I decided to use Kotlin to continue training my skill in the language I use to develop for Android. Feel free to suggest improvements or ask questions.
