Another conflicting interface

Report a typo

Resolve the conflict by only changing the code in NewLinePrinterInterface. The resulting code should print something else to the console.

Write a program in Kotlin
interface PrinterInterface {
fun printSomething() = print("something")
fun printSomethingElse() = print("something else")
}
// Do not change the code above.

interface NewLinePrinterInterface {
// Change only the code here.

fun printSomething() = println("new line something")
fun printSomethingElse() = println("new line something else")
}

// Do not change the code below.
class MultiPrinterClass : PrinterInterface, NewLinePrinterInterface {
override fun printSomething() = print("classy something")

override fun printSomethingElse() {
super.printSomethingElse()
}
}
