Today daily is 💀💀💀. Probably the hardest I have ever seen and has the most mixing concepts/patterns.

The official solution in Editorial is 100+ lines, wtf. Skip it, don't do it.

Next days I will drop my old articles (published in habr) about interview at Microsoft (offer), and Aws (reject) in 2021

I was crazy and stupid enough to reveal the questions they were asking, and answers 😅 MS folks saw that and then my manager in Microsoft told me to remove answers from article at least. I don’t do that anymore, but it was funny.

I mean they didnt sign NDA back then.

Feels amazing, especially after yesterday's crazy trie+dijkstra+dp problem, slight recall for binary search, but can be solved directly as well.

Sooooooooooo, as promised.

It was way back in 2021, it was the time I started doing Leetcode and the time dream FAANG company offer was only unreal dream

This one is about AWS interview experience. There are actually questions I was asked that time.

Today is bullshit problem. I propose you to solve similar hard question which is 1000% easier to understand and more useful to solve. The link to alternative hard task that we are going to solve in the comments.

For the daily - just copy paste from some publicly available solution

Does anyone else find talking to Cursor for 2 hours more exhausting and less enjoyable than spending 2 hours building their own understanding from documentation and sandboxing?

I mean, maybe it is only me, but it feels extremely bad, when you don't build mental model of what is done while progressing. It is a bit like you are blind, and are not doing much (like being a PM: you were in the meets, managing stuff, but actually you didn't build anything).

Okay, respect Malwarebytes. At Microsoft I would wait for few months probably xD

Within an hour I got a reply about complaint that they marked my website as riskware.

I wouldn't say it is easy easy. It just just easy, but needs a bit of effort.
