well, agree, this week was good, without math shit

We are living in crazy time. If algorithm does not know you - you are not allowed to watch youtube

A bit messy with code, but it is not much harder than yesterday's mid.

However, there is interesting topic for which Datastructures to use here (check solution in comment)

(((((((((

first I switched from c# to javascript, cause it is less messy, and realized, JS does not have minheap.

So I switched to python, that has heapq, and even less messy so that now I don't have sorted set with tasty O(log n)

Today is very easy, 2 mins, go and collect coin

For now, yes, thanks for opening my eyes, apologies, in leetcode there IS a priority queue. It is exposed by library https://datastructures-js.info/docs/priority-queue

This library is kind of preimported for your leetcode question.

How I was doing it before xDD

Actually in real interview you don't have to know this lib and use it. You can just say interviewer: yeah, I know there is a heap DS, it can be implemented using array, it has log(n) complexity bla bla bla, BUT, I will kind of assume this is the heap, and instead use array and sort it after every insert.

Am I broken? just put this stream for 3 hours, no comments only game sounds for nostalgia while working.

and it is so warm feeling, I want Lineage2 to be back, so I can spend somehow my vacation😁😁😁😁

This is gangsta shit guys

They guy is just sitting on the couch, smoking, chilling and meanwhile writing fucking game engine for POV shooter. Idk, if there was vim used, that's it 1000% TOP G.

At some point we gonna have similar streams, but I just need to get some skills, and we gonna write distributed shit.

The goal is agreed, I'm collecting money for this:

This is statistics of andreyka26.com for past year.

Does anybody know what happened on these 3 points?
I mean at some point I somehow lost TLS for half a day or day xD, but only once.

Is it AI influence?

Seems like DP, and O(n) is memory optimization for 2DP.
