if i want to learn,then i wouldn't try this way,but the situation is that this is a homework,i must finish it and hand on it on time,i still have another exam this week,so the time is too limited for me .
You SHOULD do it YOURSELF!Or you learn NOTHING.
We never get the best answer,may be we get the worst one.But anything we
did it ourselves are treasure for us,REMEMBER it.
