first of all I want to ask why all admin don’t answer the question the contest which has been in previous years? or other users why you don’t help?
another question about some more homework
explanation said that “The first 16 elements of b are” can anybody explain why the first 16 bit?
You always said that if you have any question please send to firstname.lastname@example.org. since 30.03.2013 I send a question but until now I haven’t get any email from you. I asked question but none answered why?
