document.write( "First  vertical strip can be any of 11 colors.\r\n" );
document.write( "\r\n" );
document.write( "Second vertical strip can be any of remaining 10 colors.\r\n" );

document.write( "Fourth vertical strip can be any of remaining  8 colors.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, the total number of differently colored flags is the product\r\n" );
document.write( "of four integer numbers, starting from 11, in descending order\r\n" );
