## Tricky cases[edit]

Are there any tricky cases? I've been working on this problem for days, it doesn't seem difficult, but I'm always getting WA. I've left a message here too: http://acm.uva.es/board/viewtopic.php?f=6&t=27206 but that forum looks dead. Any help would be appreciated, thanks! Giuseppe 15:03, 22 August 2009 (UTC)
