• 下下来的数据源源本本就是这样的~真不知道都是怎么ac的......~ (1330) palmtenor 2005-06-12 10:32:50
  • ft注释里还有数字......不过readln可以轻松处理吧 (0) TN 2005-06-12 10:57:26
    • 的确readln可以搞定，不过scanf呢？ (0) palmtenor 2005-06-12 11:20:28
      • 可以试一下scanf("\n");当然还有更强大的东西 (0) frkstyc 2005-06-12 11:21:18
        • scanf("\n")，用这个可以AC，但是自己用stdio调试很不方便，这时用文件就没问题了 (0) sunmoonstar_love 2005-06-12 12:53:03
