\n" ); document.write( "The second digit can be any one of (2, 3, 4, 5, 6)
\n" ); document.write( "The third digit can be any one of (5, 6) if the second digit is a 2
\n" ); document.write( "The third digit can be any one of (2, 3, 4, 5, 6) if second digit is not a 2
\n" ); document.write( "The fourth digit can be a (6) if the second digit is a two and third digit is a 5
\n" ); document.write( "The fourth digit can be a (2, 3, 4, 5, 6) if the second digit is a two and third digit is a 6
\n" ); document.write( "The fourth digit can be one of (2, 3, 4, 5, 6) if the second digit is not a 2
\n" ); document.write( "Therefore we have
