Segment tree. Previously we have discussed Heap. Today we are doing Segment Tree. Don't skip, my friend was asked question for Segment Tree during Data Brix interview - so it is asked, rarely but still. We will consider the simplest segment tree application…
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.

Overtimes, ofc
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

Daily (306/373 streak until LC cap)

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

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.

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.
