Modify the Above program to make it more user-friendly. Since the exact spelling of country names can be difficult to remember, enhance the program to allow the user to enter a single character at the prompt to display a list of countries whose names start with that letter. Use a dictionary whose keys are letters and whose values are sets of country names that begin with a given letter.
