For today's daily, people suggest to solve this question:
https://leetcode.com/problems/largest-rectangle-in-histogram/

it should be actually good, but I'm a bit struggling to finish it. So seems like tomorrow's daily is going to be pretty hard.
There is also a note that max area rectangle is solved COMPLETELY different way than max area square.

Daily (155 day streak).

Well, today is pretty hard question. As I mentioned above, better to solve the question before that, which will be used as subsolution to today's daily.
I'm just happy it is Sunday and I was not in a rush

Daily (157 day streak)

Today is pretty interesting problem. Binary search on real numbers. I would not say it is very easy, and it uses some sort of "unique" technique that you never seen before.

I'll be honest with you I don't give a shit about how to solve it, because of above.
I mean segment tree on it's own is already hard enough thing. Now we should put it, add sweep line and hell knows what else.
Instead of this I would do some hard task from top 100 liked questions, sorry, go unsubscribe if I disappointed somebody

Punishment problem (for not solving daily)

From top 100 liked questions. I would not say to be honest that it is hard. I would rate as mid.

Daily (159 day streak)

Today, is good medium problem. And very nice hints in case you don't come up with intuition.
Just small hint from my side, you must return maximum SQUARE, not rectangle. This what was not working for me.

Don't be scared by 20% acceptance rate, actually it is not hard. Hints are again very useful, and basically will give you a solution.

Daily (161 day streak)

Today is pretty nice and interesting problem, that involves a bit of Cortasian plane knowledge and a bit of geometry knowledge, but very basic one.
