Problem: printStrings

  Write a static method printStrings
   that takes as a parameter a Scanner holding a sequence of integer/String
   pairs and that prints to System.out one line of output for each pair with
   the given String repeated the given number of times.  For example if the
   Scanner contains the following data:

        6 fun. 3 hello 10  4 wow!

   your method should produce the following output:

        fun.fun.fun.fun.fun.fun.
        hellohellohello
        
        wow!wow!wow!wow!

   Notice that there is one line of output for each integer/String pair.  The
   first line has 6 occurrences of "fun.", the second line has 3 occurrences of
   "hello", the third line has 10 occurrences of "" and the fourth line has 4
   occurrences of "wow!".  Notice that there are no extra spaces included in
   the output.  You are to exactly reproduce the format of this sample output.
   You may assume that the input values always come in pairs with an integer
   followed by a String.  If the Scanner is empty (no integer/String pairs),
   your method should produce no output.
