Problem 9.(a) Page 266 of textbook.

   Draw the two set arrow diagram for the Spanish word binary
   relation, as described in the textbook.

   Draw the function for ONE of the other languages listed above:
                         ---

   f(word for number) = set of vowels in the word

   Note:  Function f is a mapping 
              from words to the PowerSetOf( {a, e, i, o, u} )

   Since | PowerSetOf( {a, e, i, o, u} ) | = 32, you do NOT have
   to list out the entire codomain in your two-set arrow diagram!
   Just imply the elements that are not part of the range of function f
   in your diagram.  For sure, you can add the empty set and the set
   {a, e, i, o, u} to the diagram but need to only have the other
   ones that are in the range of f.


Based on problem 10B, page 280.

Let B be the set of binary strings of length 8.

Define h: {0, 1, 2, 3, 4, 5, 6, 7, 8) ----> B
 
     where h(n) is the binary string 
                           consisting of n 1's,
                             followed by 8 - n 0's.

PROBLEM 10EEE.  Enumerate the Range of function h, 
                          i.e. the set of y such that h(x) = y
                               with x elementOf {0, 1, 2, ..., 8}.

Let k be a function defined as follows:

   k: B -----------------> N (where N is the Natural numbers set)

   k(n) = the base ten, decimal value of binary string, binary number n

PROBLEM 10FFF.  Enumerate (list) the set that is the range of function k.

    Note:  if you study computer networks, you will become very familiar
              with these 9 numbers as they are all found in subnet masks.

          Example subnet mask for a class B network:  255.255.240.0
