Re:终于AC了,但是不明白,为什么用cin,cout,超时,用scanf,printf,就能ACIn Reply To:终于AC了,但是不明白,为什么用cin,cout,超时,用scanf,printf,就能AC Posted by:wanghaishanren at 2008-04-30 19:38:39 > 终于AC了,但是不明白,为什么用cin,cout,超时,用scanf,printf,就能AC 用流会慢很多很多很多。那天在北航做那个什么银河大战的那个，也是并差集。我知道cin费时间已经把大部分都改成scanf、printf了。就落了个读那个'M','C',我用的cin，结果超时，10s的题啊那是，后来改成scanf，就1s过了 Followed by: Post your reply here: |
