Daily 412th day streak

I was not able to solve in reasonable time. The problem is amazing otherwise (except very poor explanation/definition). Definitely recommend. I will work later today on more solutions and understanding of them.

Daily 413th day streak

Pretty easy problem tbh. No specific pattern though, and sort of does not feel like bullshit, more or less applicable.

Amazing problem, has very simple pattern, seen this one many many times -> definitely recommended. The problem itself is pretty easy

So I got interesting thing about my body.

Probably all of you are getting 1-2 times sick (cold) per year (at least this is how it was for me).

I noticed few years, that if I have some important events in life (like meeting somebody, interview, oncall, etc) - I subconsciously tell my body: "we cannot get sick now, later". AND IT WORKS!!! (most of the time).

Then once important event is done, and I'm relaxed, same command: "now we can have sickness for a bit" and then it gets worse as usually sickness should go.

Do you have the same?

Very shitty described question, BUT not hard to implement actually. Go to comment section to understand it faster.

No pattern though
