Today is graph problem. I love graph problems. But it requires again a bit of coding, and a bit of graph algo's knowledge.

Mid, but it is close to hard I would say for building an intuition

Not that bad, but a bit bullshit. It takes a bit long to build an intuition (I will leave hint for that in comments)

Actually a nice one. Kind of "area" line sweep. Nice to learn a bit.

The hint: the intuition you can derive from is try to do it with 1D array and columns updates on it.

As I told you before, daily is piece of shit. No way this is medium. But yeah.

Nice problem, pretty easy. But you need to recall how to do arithmetic progression: https://en.wikipedia.org/wiki/Arithmetic_progression

Nice problem, even though I didn't figure out the intuition right from the first time.

A bit of math bullshit, does not recommend, but with hints and simple run in the head it is not that hard.
