Add Kotlin to the supported languages
By kirjuri, history, 10 years ago, In English

I have been experimenting with Kotlin lately, and it's a very simple and comfortable alternative to Java (at least in the scope of programming contests, I cannot find a case where some solution written in Kotlin would be uglier than the Java equivalent). Moreover, Codeforces supports Scala, which also runs on JVM, it's a much more expressive language with more advanced features, although they are useless for the competitive programming context: thus is makes more sense to add Kotlin (also|instead).

I would like to know what people think about it, and if I can contribute anyhow to make it possible, I would like to know as well. Thanks!

Totally agree! This way, we can learn not only coding skills but also a programming language on Codeforces. If possible, please also consider Julia too.

Well, creating several dimension array (3d for example) is (or at least was) uglier than in Java

    Why Java is ugly?

    C++:

    int threedim[5][10][4];
memset(threedim, 0, sizeof(threedim));

    Java:

    int threedim1[][][] = new int[10][5][8]; // (1)
int[][][] threedim2 = new int[10][5][8]; // (2)

    C#:

    double[,] twodim = new double[10,9];
double[, ,] threedim = new double[10,9,5]; // (1)

double[][] twodim2 = new double[10][]; // (2)
for (int i = 0; i < twodim2.Length; i++)
	twodim2 [i] = new double[5];

    Python:

    w, h = 8, 5. 
twodim = [[0 for x in range(w)] for y in range(h)] # What the hell

It would be a great idea. It was already supported in the surprise language contest before so it won't be a huge work :D
