Very easy, 2 mins, and should be labeled as easy. Sometimes I truly don't understand leetcode complexity ratings.

And 2 hints, I mean, why xDDDD

Daily, pretty easy, just simulate the process

Eventually autumn time - time for Beatles

System design - done
Win some matches cs2 - in_progress

Inprogress -> done

Description is a bit nonsense, but it is easy, as simple simulation works, and constraints are constants pretty much.

hard one, wasn't able to solve on my own. The solution is not that intuitive, therefore, if you don't have much time - don't do it

The most classic one, most probably all of you solved it many times as it is 11th problem:

Highly recommended, I like this guy (older), what he says makes a lot of sense

Personally enjoyed, even though it wasn't 10 mins for me.

Hint to understand the description, you need to return ALL cells that will lead rain watter to BOTH atlantic and pacific (not paths, just the fact that they will pour to both).
This means that left row and upper row will always be pouring to pacific as well as right row and bottom row always be pouring to atlantic

Don't be scared, it is not that hard. Just very stupidly formed question. It asks basically to find the path from (0,0) to (n-1,m-1) with the minimum values inside the path

ANNOYING SHIT.
When you see acceptance rate 33% for mid problem, it always will be, but what I hate the most is again fucking misalignment in complexities. (Explanation in comment along with the solution).

Also understandable rephrasing of the problem in comment as well. Description is FUCKING SHIT, I don't know what motherfuckers are sitting on leetcode who create these descriptions. Literally every single person complained about the descriptions.
