document.write( "The set contains 4 integer numbers 1,2,3,4.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, the number of all subsets is  = 16.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Exclusing one improper subset, you obtain 16-1 = 15 proper subsets.    ANSWER\r\n" );
