To really master functions, I’ve prepared two challanges for you!

Challenge 1:

Create a function which takes in two parameters - a name and a last name. 
Because not everyone has a last name,
leave the lastName parameter to be an empty String if it is not passed in.

Then return the length of the person's full name is.


Challenge 2:

Overload the function from the first challenge, by adding a list of Strings parameter, for middle names,
in case someone has one or more middle names.

Use the function to return the full name length, for a name with and without middle names.
Remember to use named arguments if needed.
fun getFullNameLength(name: String, lastName: String = "") = 
	name.length + lastName.length
val nameLength = getFullNameLength("Ayo", "Balogun")
println(nameLength)
fun getFullNameLength(
    name: String,
    middleName: String = "",
    lastName: String = "",
  ): Int {
  
  return name.length + middleName.length + lastName.length
}
val length = getFullNameLength("Damini", "Ebunoluwa", "Ogulu")
println(length)
