I don't know who you are, but let there be a divine cure upon you for creating this.

I came up with the same solution but I genuinely tried various approaches before this. I love mathematics because there is always an alternative pattern to recognize and you can tackle problems from various angles. I think I gave this about ~2 hours before I just realized what I need to do but I actually enjoyed this.

I understand everything about this, except for why the "i" actually works as the repeat attribute? Why does this work? I understand everything about it except for that. I looked up various description about how the map function is supposed to work but I just don't get it. I used map before and it always did what I thought it would but in this case I'm just stumped.
