Daily 359th day streak

Don't be scared, if you have solved yesterday's and the day before yesterday's problems - it should be easy-mid for you.

The problem is good, it has a pattern, game theory + dp. Amazing one, definitely recommended.

Dealing with stock broker application is always "amazing"/strange experience.

Now I wanted to fill some form, it shown me an error. Then I got phone call (automated from US) with the message: "Hey, there was an application error, good bye"🗿🗿🗿

Oh my god I got so many clowns in threads that try to educate me on async/await in js and in general in other languages

So the question:
What is async/await, why is it used?
You can answer for your language as it will be a bit different according to thread model that is used in it.

Throw few words below

Would you be interested in article about async await in differential languages, literally underhood / hardware level?

I have notes for that, as 2018-2022 I was doing a lot of outsource companies interviews, and I learnt it very low level for .net/c#, js and python.
Seems like a pretty confusing topic.

Not sure it is needed that much nowadays with ai to be honest.

Check the comments section. What a beasts we have here in this channel.

I am proud of you. I am not JS guy, learnt it a bit many years ago, but today from our comments learnt a bunch of new things, low level with official doc refs, exactly how I like it.

Respect guys🤝🫡

Daily 362nd day streak

It took me some time to come up with nice solution, but in general, since easy - any bruteforce will fit here.

No pattern though.

Btw the guy is crazy. I thought I am the “early bird”, started working when I was 18, had pretty much only first year of uni and then skipped most of the stuff

But Maksim started doing freelance tasks at 16-17, and IN THE BEGINNING of the first year in uni, when he was 17 - he interviewed and got a job🤯.

Practically, he fully skipped uni. Legend. Big respect

Yeeea, flashbacks in instagram dm. This is how all “blogging” thing and andreyka26.com started. There was no-one explaining authorization like I do: deep, with all questions and reasons behind what’s done covered, detailed step-by-step, etc

So I investigated, built, made a video and article, and in 2023 +- it got pretty high attention. But not anymore, I think now claude might explain it better, maybe. Side thing, I dont need this explanation anymore as I have RFC snapshot about oauth in my head😁
