| 8 | Hi David - thanks for that. |
| 9 | |
| 10 | So [[:digit:]] is another way of writing [0-9] and the + just means another |
| 11 | instance of the proceeding expression, right, so your and Francois |
| 12 | solutions are functionally the same, and all the following are the same |
| 13 | too, right? |
| 14 | |
| 15 | [[:digit:]]+ |
| 16 | [[:digit:]][[:digit:]] |
| 17 | [0-9]+ |
| 18 | [0-9][0-9] |
