Kotlin Exercises practice with solution

Kotlin Programming Language

Kotlin is a cross-platform, statically typed, general-purpose high-level programming language with type inference. Kotlin is designed to interoperate fully with Java, and the JVM version of Kotlin's standard library depends on the Java Class Library, but type inference allows its syntax to be more concise.

Practice exercises are the most effective way to learn coding. We have started this section for those (beginner to intermediate) familiar with Kotlin programming.

We hope these exercises will improve your Kotlin programming skills. Currently, the following sections are available. We are working hard to add more exercises. Happy Coding!

More to Come !

Do not submit any solution of the above exercises at here, if you want to contribute go to the appropriate exercise page.

Note : Since JavaScript is a loosely-typed, dynamic and expressive language, you may accomplish the same task in various ways. Therefore the ways (solution of the exercises) described here are not the only ways to do stuff. Rather, it would be great, if this helps you anyway to choose your own methods.
