Assume you have implemented the following functions

def factorial(n: Int): Int = { ... } // code not provided

def formatResult(name: String, n: Int, f: Int => Int) = {

val msg = "The %s of %d is %d."

msg.format(n, f(n))

}

def main(args: Array[String]): Unit = {

println(formatResult("factorial", 7, WhatShouldYouTypeHere)) }

WhatShouldYouTypeHere shall be replaced with what information so you will be able to print the following results when calling function main

The factorial of 7 is 5040

		A.7
		B.5040
		C.factorial
		D.all answers are wrong
