Write a method appendIfMissing which is passed a String s and a String e (for ending). If s doesn't already end with e, the method returns a new String which consists of the contents of s concatenated with e. It returns s otherwise.
For example, if s refers to the String "lightningbug" and e refers to the String "bug", the method returns "lightningbug".
If s refers to the String "Airplane II", and e refers to the String ": the Sequel", the method returns "Airplane II: the Sequel".

The use of phrases, fragments, and punctuation can influence the mood of a passage; keeping this in mind, how would you describe the mood of the followingpassage? "fog on the essex marshes, fog on the kentish heights, fog creeping into the cabooses of collier-brigs; fog lying out on the yards, and hovering in the riggingof great ships; fog drooping on the gunwales of barges and small boats. fog in the eyes and throats of ancient greenwich pensioners, wheezing by thefiresides of their wards; fog in the stem and bowl of the afternoon pipe of the wrathful skipper; fog cruelly pinching the toes and fingers of his shivering little'prentice boy on deck."
