Kotlin: how to pass a function as parameter to another?

Question

Given function foo :

fun foo(m: String, bar: (m: String) -> Unit) {
    bar(m)
}

We can do:

foo(\"a message\", { println         


        

Answer 1

Another example:

 fun foo(x:Int, Multiply: (Int) -> (Int)) {
    println(Multiply(x))
 }
 fun bar(x:Int):Int{
    return  x * x
 }
 foo(10, ::bar)
