The rules:

First I solve problem by myself (for this one I needed around 20 minutes).

Then I write the code slowly when filming a video and explain what I did, and where I made mistakes and where I struggled.

I can use all the materials I can find online, but I mustn't look for the exact code that solves the problem,
I left the links above that helped me solve this puzzle.

If I can't solve a problem independently, a move on and come back later, to try it again, when my knowledge expands.
