As was forecasted yesterday: it is segment tree, and it is hard one.
But with hints + and our segment tree pattern it is not hard to solve.

Again, recall this pattern, after doing that I was able to write min/max segment tree in one go.

Putting a reminder: I have a friend who got asked segment tree question in big tech. So it is getting asked.

Btw, this is not company related thing, I drew it, it is kernel network hooks. You all have it on your machine and on your servers

Not bad problem, not a bullshit (since graph/tree ofc). But I would still rate as true medium

Vibe like Jack Sparrow is somewhere inside

Dont worry, daily leetcode will be posted later, now I am fighting with bank to get 100 eur by coins.

Daily is quite interesting follow up from yesterday, that has multiple patterns, so I need a but more time to prep it for you.

After 4 months I eventually got my coins, I am happy

In case you dont know how 100€ in 1eur coins look like - this is how.

Ahhahaha somehow first impression is casino.

I dont know, my experience in Prague was: you go with at least 1k czk(50€), you pay them, you get chips, in the end if you are not me and don’t lose all money in poker - you exchange chips for cash.

Never had to have 1 eur coins for that, but I am interested, maybe I should use it.

Btw this was my first monthly salary as swe in my first company back then in 2018😁

Was enough to eat whole month + free cookies and tea in the office

Interesting problem, pretty tough and has the pattern I see first time in my life. Up to you.

Did you know that we are already done?
it is on default free gpt model, same on claude, and gemini.

As my friend suggested, most probably they are generating deterministic code and run it to get the answer.

Today is easy one, Happy Saturday. It is a bit bullshit tbh.

I found what I am gonna be doing when AI finally replaces me

Amazing problem, no jokes. It is non-bullshit, probably from the list, and uses 2 most popular linked list patterns.

Highly recommended. Note though, you should solve it in O(1) space complexity.

I have already mentioned that I'm now fully vibecoding everything. I don't event bother to open PR - AI does it.
Do I enjoy it - yes, but a bit less.

Let's separate work related and personal projects.
