   3 Solution of exercise 2.30:
   4 (Separating Digits in an Integer) Write a program that inputs one five-digit
   5 number, separates the number into its individual digits and prints the digits
   6 separated from one another by three spaces each. [Hint: Use combinations of
   7 integer division and the remainder operation.] For example, if the user types
   8 in 42139, the program should print
   9
