At the beginning of 1990, a complete box of Crayola2 crayons had 72 colors (in the file Pre1990.txt). During the 1990s, 8 colors were retired (in the file Retired. txt) and 56 new colors were added (in the file Added. txt). Write a program that creates a text file containing the post-1990s set of 120 colors in alphabetical order. Note: The first four lines of the new text file will contain the colors Almond, Antique Brass, Apricot, and Aquamarine.
