Kotlin supports a variable number of arguments in functions as in the following code:

fun sum(vararg nos: Int): Int {
    var result = 0;
    for(no in nos) {
        result+= no;
    }
    return result;
}

These can be invoked with a varying number of arguments, such as the following code:

println("Sum of 1, 2, 3 is ${sum(1, 2, 3)}");
println("Sum of 0, 9, 8, 7, 6, 5, 4, 3, 2, 1 is ${sum(0, 9, 8, 7, 6, 5, 4, 3, 2, 1)}");
