program bubble(input, output);
{ Program   : bubble
  Input     : 1) Number of data items (maximum 500)
	      2) The data items  Operation : Sorts the data using a bubble sort, the number of comparisons
	      and data accesses being counted.
  Output    : The number of comparisons and accesses and the sorted data	      in ascending order.  Bugs      : 1) The program does not check for invalid data type on input
	      so entering an invalid integer will cause a fatal crash.
