Kotlin Koans
Kotlin Koans are a series of exercises to get you familiar with the Kotlin Syntax. Each exercise is created as a failing unit test and your job is to make it pass.
Open up the project in IntelliJ IDEA or your favorite editor. Run 'All tests' and fix them.
How to work with Koans using this project
You have 42 tasks to do.
Each task lives in its function: from task0 to task41.
You regularly have to change the function taskN by replacing its body (which starts out as the function invocation todoTaskN()), with the correct code according to the problem.
The function todoTaskN() throws an exception, so you have to replace that invocation with meaningful code.
Using documentation argument you can open the related part of Kotlin online documentation.
Press F1 (Quick Documentation) on docN(), then "See also" section gives you a link.
Using references argument you can usually navigate and see the code mentioned in the task description.
The repository has two branches, master which contains the exercises for you to do and resolutions which contains the resolved exercises.
Make sure you don’t cheat!
