Switch statement practice. Given a character ch, return the morse code representation. Only the uppercase letters 'A' through 'E' and the numbers 1 through 3 will be translated. If the given character cannot be translated, return "UNKNOWN". [A = .- ] [B = -... ] [C = -.-. ] [D = -.. ] [E = . ] [1 = .---- ] [2 = ..--- ] [3 = ...-- ]
