The road to wisdom?—Well, it’s plain
and simple to express:
Err
and err
and err again,
but less
and less
and less.
— Piet Hein
The Goal: Given a starting “sentence” (string) reach the goal “sentence” (string) by only applying the rules below.
| Rule | Example |
|---|---|
| Mx → Mxx: | MIIU → MIIUIIU |
| xI → xIU: | MIIUI → MIIUIU |
| xIIIy → xy: | MUIUIIIU → MUIUUU |
| xUUy → xy: | MUIUUIIIU → MUIIIIU |
x and y represent any character strings and M, U, I represent the actual letters, the arrow may be read as “becomes”.
For example the first rule can be read: Any string that ends in M becomes M and two times the reminder.
Try it, I will be waiting here :).
