A very special testcase is the following sudoku:

```9-6-7-4-3
---4--2--
-7--23-1-
5-----1--
-4-2-8-6-
--3-----5
-3-7---5-
--7--5---
4-5-1-7-8
which has two solutions:
```926571483
351486279
874923516
582367194
149258367
763194825
238749651
617835942
495612738
and
```926571483
351486279
874923516
582367194
149258367
763149825
238794651
617835942
495612738

AFAIK, a "good" SuDoKu puzzle should have a unique solution.

Flavio
perl -ple'\$_=reverse' <<<ti.xittelop@oivalf

Io ho capito... ma tu che hai detto?

That's true; but if you are beware of such strange user input, it's easier to write tests and make sure that such strange user input is also handled correctly...

Best regards,
perl -e "s>>*F>e=>y)\*martinF)stronat)=>print,print v8.8.8.32.11.32"
