IMO, it should be hard, as extremely hard to get with intuition. I wasn't able to solve and was hard to understand the solution tbh

Next days I will drop video about this system design, with drawing and explanations

Amazing problem. In general it is much more enjoyable to solve some "real world" modeled problems. However took me a bit to come up with an idea.

Solid and good problem. Go to comment section I will explain how "carry" works for binary summing.

So, the problem, labeled as easy.
We need to make string, containing only "a" or "b" empty, by removing palindromes only.

Problem is not about coding or using some algo, more like brain puzzle, and hoping "Eureka effect" hits you before you go to hint.

Easy problem again, not bad one, but you will need some hint (check the comment) to not waste 10 minutes as I did.

Leetcode gave me a cap in credit for consistency. Now there is no way I'm not getting these 6500 coins to pay back.
Only 180 days left

Not bad problem, however I wouldn't call it easy, feels like mid, but nice one. Go to comments, I left good hints there

Easy today, I'm very worried for tomorrow as we had 4 easy problems in a row...

A bit of Dublin on my way back. Like this city

I'm not kidding, we are fucked tomorrow, some DP, graph, bits, monotonic stack in one shit will pop up

Daily (194/373 streak until LC cap)

Easy as well, but bruteforce won't work here, so you need a bit of time to come up with the idea.

I'm wondering, how YouTube algo works??
In some random point of time it might decide to show your video for some reason and start growing from that point.

However I like this more than tiktok (random boom for random video for now reason whatsoever), or instagram(just dead shit, not a single one get's boom)

Wanted to fall asleep at 12. Also me 01:10:

I dont fucking understand why this world works like that.

There is human being. Human being(me) has to be active during daylight + 3 hours when it is dark.

ALL remaining hours of dark time human being(me) should fucking sleep to get 8 hours of sleep to not die because of immunodeficiency.

===

But my body has completely different opinion on that. It cannot wake up in the morning, acts like veggie whole day, then half veggie in the evening and then FULL FUCKING ENERGY FROM 10 PM till 2-3 AM. During the day ofc, this human being(again me) cannot drink coffee cause of stomach and reflux, bravo

One thing I love about Snowflake in Dublin and my team is that you can get adhoc casual lecture about TCP/IP stack lecture from our principle engineer who is ex-Googler for 10+ years on random Tuesday.

This was the best lecture about TCP/IP stack. Guy went deep explaining electrical signals and how transfer of bits happens under-hood, and up to the HTTP/DNS.

This itself matters a lot. Pity that they don’t put it as benefit to offer, I think it would be NOT rejectable after this at all
