Always love a puzzle 🙂 so here's my solution. I'm not sure if my grouping method will work further down the line, however it seems to work for 10 iterations. There is probably a better way of doing this.[/code]
Thanks for your contribution,
Using your solution I saw that the conclusion of that the string is going to loop is not correct. (And therefore my suprise was not correct).
So I have to retract that conclusion now. (Sorry).
Yes it is a very elegant puzzle. (Is my opinion).
