if remainder 1 or 2. In case of remainder 2 , we divide elements from 3 to n in groups of size 4 and put 1 in one group and 2 in group . This also makes difference 1.
if ( n % 4 == 1 n % 4 == 2 ) { document . write ( " " + Math . floor ( s / 2 ) ) ; document . write ( " " + Math . floor ( s / 2 + 1 ) ) ; document . write ( " " + 1 ) ; }
