Question 1120348
.


It is fine that you just learned how to "copy and paste".


But this forum works in other way.


It is NOT our goal to work instead of you and/or to substitute you in doing your job.


It is not our goal to serve industrialists who post tens of assignments in one mail.


Our goal is to teach the students in this forum.



Therefore, the <U>RULE OF THIS FORUM</U> is:


<H3>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ONE and ONLY ONE problem per post</H3>


And one more notice:

<pre>
    From your post, I clearly see that you even do not read what you posted.

    Otherwise, you'd notice that the problems #3 and #4 are the same.
