I'm not sure whether you intended a trailing ', ' in the output. If not, you could use parentheses

.oO you got me ...

If I'd say now "I didn't care if a trailing comma would show up" nobody would believe me. If I'd say "I tried to make the output of print "@strings\n"; more distinct for a beginner", the same would happen.

Therefore the best would be to take the blame and admit failure ;-)

Thanks & Regards
