Maigo Akisame (maigoakisame@yahoo.com.cn) ICY. You get WA when S=F. The prob statement doesn't say it's impossible. [2] // Problem 1277. Cops and Thieves 21 Sep 2004 20:07
but i find Test26 is not S=F,why?
Maigo Akisame (maigoakisame@yahoo.com.cn) Maybe you treat the edges as single-directed. But in fact they are double-directed. // Problem 1277. Cops and Thieves 24 Sep 2004 20:39
