Passing function as parameter

Example:1

Output

Result of Addition:-> 3
Result of Multiplication:-> 1

Code

fun main(args: Array<String>) {

    val input = listOf(1,1,1)

    val resultAddition = performOperation(input,::addition)
    println("Result of Addition:-> $resultAddition")

    val resultMultiplication = performOperation(input,::multiplication)
    println("Result of Multiplication:-> $resultMultiplication")

}

fun performOperation(input : List<Int>,operation:(List<Int>) -> Int): Int {
    return operation(input)
}

// * ****************** Operations ******************
// ADDITION
fun addition(input:List<Int>): Int {
    return input.sum()
}
// MULTIPLICATION
fun multiplication(input:List<Int>): Int {
    var result = 1;
    input.forEach { result *= it }
    return result
}
