Why Time Travel Should Never Be Attempted

Now, when I say this, I mean traveling "back" in time. Now, the reason for this, is the Infinite Loop. What is the infinite loop? The Infinite Loop is what would happen if someone were to travel back in time, and fail to meet their original point of insertion, to be more precisely, the precise time at which they traveled back in time. This would cause time to infinitely loop back and forth from the present to the past without ever reaching the future, because the Present is the constant at which the future is judged and created, and without that constant, there can be no future.
Why is this? Well, assuming that alternate timelines don't exist within this same universe (and why would they), there is a constant that is always present which signifies the future, or at least what will be, this being the present. If the present, or some aspect of it, were to travel back in time, along with it having already of happened at some point, it would delay the future from occurring, since now the present has been replaced back in the previous line of time. The only way this problem could be fixed, would be for the present to eventually return back to its current timeline, and not through the regular process of time, since then that would effectively cause the entire universe to split in half (imagine someone tearing a piece of paper in half to create to separate pieces).
The present would need to return back to the exact infini-second (word I made up to signify the impossibly smallest increment of time that's calculable) in order to prevent this split from occurring.
The reason this wouldn't be a problem for traveling into the future is quite simple really, you wouldn't be forcing a loop. The constant would simply be moved ahead instead of being looped infinitely to satisfy the future, which is actually the present. If we've already had time travelers in the future, then we're screwed.

These are the contents of a text file. It shows a student's name, followed by a list of their scores in a maths quiz. I need to "r" this and:
>sort the students in alphabetical order with each student's highest score
>sort them by the highest score, highest to lowest
>sort them by average score, highest to lowest.
I should be able to run the program, type in one of the three ways of sorting it and it should print out the sorted list. A solution with an explanation would be ideal.

In a philosophical sense, what do complex numbers mean? Are they just a clever mathematical trick that works for certain problems or are they a physical quantity that has meaning?
From my understanding, the imaginary part is always ignored at the end of the problem/ calculation. Is this always true? Is there a problem when the imaginary part has some actual, physical meaning?
As far as I've gotten in physics, they've been mostly used so that you can equate the functions e^x and the real part of cos(x)+i*sin(x) so that the real part of the integral of cos(x) can equal cos (x) (and the same when you differentiate it).
Apologizes in advance for lack of latex, i just don't know what I'm doing when it comes to the syntax.
