if by taking dont care you get a mapping of 2,4, 8 subcubes then you need to include it , otherwise, ignore it.

include means you took don't care = 1 in case of SOP and 0 in case of POS.

if I map a subcube by taking 1 x   ( don't care condition) and if I take 2 x (don't  care condition ) then i can map a large subcube  then which one i have to select ????
