Interesting, giving like to this
This gave me a challenge This is a really nice puzzle! Not too easy, but the solution is cute and not too complex.
Of course, the flattery helps too. Not a disaster.
The left side is a bit underdeveloped to me. Carl's find is super nice! That's a nice trick! Good find FlashBack I had to take a break and come back with a fresh mind, but this is a cool structure! Enjoyable, especially the optimization work Same impression as alazeh.
