editing the tex file

[ziesski]

So if we do the entire tex, then there will be over 200 pages, a lot of questions.
I did edit problem 1.1 in the format I wanted, but I cannot do it for the entire questions.
Instead, we can parse the tex file, and for example if there is string Problem int.int /n then wrap it with \textbf{}
and add a line divider for each question.

Write c++ code, I guess python should be easier, to do this function.
