| Oct 25, 2016 at 20:35 | comment | added | Todd Trimble | @Sergei Could you give the link to where it is posted at dxdy? Is it a contest problem? | |
| Oct 25, 2016 at 18:42 | comment | added | Sergei | This is a well-known problem, also posed on dxdy forum. Why to ban it immediately for no reason at all? Let start a company to ban a band of unprofessional banners! | |
