Look inside for more information Find the longest number between 1-9999 in the comments WITHOUT LOOKING IT UP and no decimals best i have is 9997 with 179 turns A cool thing to do is compare numbers that end up near the other number for example put 1234 and then 27 or 97 and 47
I saw a youtube video and got interested https://www.youtube.com/watch?v=094y1Z2wpJg It gives an explanation as well as some history to it
