Create a function that takes a string (a random name). If the last character of the name is an "n", return true, otherwise return false.
isLastCharacterN("Aiden") ➞ true
isLastCharacterN("Piet") ➞ false
isLastCharacterN("Bert") ➞ false
isLastCharacterN("Dean") ➞ true
The function must return a boolean value ( i.e. true or false).
