Help Modify the definition of the function

Modify the definition of the function named greeting to return a String and replace the println statement with a return statement. The function should return a greeting. For example, if you pass in a string "Tom" then the return string would be: "Hello Tom"

returns.swift
func greeting(person: String) {
  return Hello
}

It is also possible by string interpolation.

func greeting(person: String) -> String {
    return "Hello \(person)"
}

greeting("Tom")
