The barcode used by the U.S. Postal System to route mail is defined as follows: Each decimal digit in the ZIP code is encoded using a sequence of three half-height and two full-height bars. The barcode starts and ends with a full-height bar (the guard rail) and includes a checksum digit (after the five- digit ZIP code or ZIP + 4), computed by summing up the original digits modulo 10. Define the following functions: • Draw a half-height or full-height bar on stddraw. • Given a digit, draw its sequence of bars. • Compute the checksum digit. Also define global code that read in a five- (or nine-) digit ZIP code as the command-line argument and draws the corresponding postal barcode. Value Encoding 1 ll 2 ull 3 ul.
