Write a method called switchFirstTwoLastTwo that takes a String as it's parameter and returns a new String with the first two and last two characters switched. For example a call of switchFirstTwoLastTwo("hello") would return the String "lolhe".

However, if the String passed into the method is shorter than or equal to 4 characters or if the String starts with "ne" or if it ends with "s", just return what was passed into the method without switching any characters.
