Uh, this is way better than mine. I didn't take into account that with the same regex I could make the replacement that way. Really good one.

nice way to get the interval.

Oh, so clever.

oh, it was bool() what I was looking for. So simple and I didn't figure it out.

This is the easiest one if you did the other parts.

I did the same but with another outlook.

I didn't know about the existence of := operator. So many times that I wanted to asign a variable in a statement and now I know it is possible. Thank you so much.

Too easy for a 5 kyu I think.

I just proved this code and realized how brilliant it is. Idk how you people come up with this kind of code, is insane. Great job!

Very good code. The perfect one.

Me neither. After 7 years did you get it?

ohhh, thanks. I didn't read that part. I'm YGO player.
