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

Daily (192/373 streak until LC cap)

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...

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)

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
