When I see such problems, posted in series of several  (5 - 7)  in one cycle,


                it really scares me.


Because I see that the person / (the visitor)

        - does not work on his  (or her)  own,
        - has no any intention to do something on his (or her) own,
        - and even has no a goal to learn the subject
        - and relies that other people (the tutors)
            will make his  (or her)  job,  instead of learning and doing it on his  (or her)  own.


Working for such a person is directly opposite (orthogonal) to the goals of this forum.
