这两者不相关吧，去查一下看 (0) hawk 2005-04-25 12:44:29
抽屉和容斥....没什么关系吧 (0) ArXoR 2005-04-25 12:45:54
- 我也觉得是，可能不是一种方法把，反正我是用抽屉原理构造的 (0) TN 2005-04-25 12:46:51
- 混了……这个题从抽屉的角度去想ms比较容易明白，所以有O(n)的构造，假如是容斥，找什么集合来交交并并的呢？ (0) frkstyc 2005-04-25 12:48:44
  - 抽屉原理？怎么构造抽屉呀，能说得更详细一点吗？thx (0) cpp051300448324 2005-04-25 13:19:13

    - 就是说，S1-Sn,如果有一个模n=0,那就可以了，否则一定有两个模n余数相等，那就取这两个的差 (0) TN 2005-04-25 21:33:10
      - 抽屉原理果然简单，我开始强搜100多ms,thx (0) cpp051300448324 2005-04-25 21:57:45
