-    a. Print the numbers 0 - 20, one number per line.
-    b. Print only the ODD values from 3 - 29, one number per line.
-    c. Print the EVEN numbers 12 to -14 in descending order, one number per line.
-    d. Challenge - Print the numbers 50 - 20 in descending order, but only if the numbers are multiples of 3. (Your code should work even if you replace 50 or 20 with other numbers). */
