Is there any good explanation for the idea behind finding max area sub-rectangle in a histogram problem? And some tasks involving the same idea. It seems to be used in much harder problems as a sub-problem and i am having hard time about it.

I am not sure what problem you are talking about. Is it like this one?

If yes, solution of it is pretty classical and you can read about it here

A simple stack implementation solves this problem, try to see if you can see why.
