At the end of movie credits you see the year movies are produced in Roman numerals, for example, MCMXCVII for 1997. To help the production staff determine the correct Roman numeral for the production year, write an applet or application that reads a year and displays the year in Roman numerals.

Remember that certain numbers are expressed by using a “subtraction,” for example, IV for 4, CD for 400, and so forth.
