As many of you out there, I like to think a bit more on the problems that I could not solve during a contest and try to solve it on my own after the contest is over.

However, when we open the problem statements, the "Problem Tags" already give a hint what technique(s) to use for solving such problems and that is often a spoiler in the direction to think for the solution.

Why not hide "Problem Tags" in the famous "Spoiler Tags"? In such case, the problem tags are hidden by default when we open the problems and if we are really stuck on the problem and need a hint, we can open the spoiler tags.

What do you think? Pour your point of views.

Dears,

I would like to know if there is a "syllabus" that the problem setters follow to create the problems.

I know IOI has one (found at: http://ioi2017.org/files/ioi-syllabus-2017.pdf).

Not sure about ACMICPC.

What about codeforces?

Thanks!

Hi guys,

I would appreciate your ideas for solving the Space Pizza problem.

Apparently, there was an O(N²) solution, but I could not find it.

Thanks for your inputs.
