    The "deleteData(offset,count)" method raises an

   is negative. 
   
   Retrieve the character data of the last child of the
   first employee and invoke its "deleteData(offset,count)"
   method with offset=10 and count=-3.  It should raise the
   desired exception since the count is negative.
