先附上一份標頭檔

ZOJ的編譯器很不習慣。經常出現編譯錯誤。很多時候是因為缺少標頭檔

我也懶得記那個函數要用到哪個標頭檔。常用的都寫上就OK了：

 

#include "cstdlib"<br />#include "cctype"<br />#include "cstring"<br />#include "cstdio"<br />#include "cmath"<br />#include "algorithm"<br />#include "vector"<br />#include "string"<br />#include "iostream"<br />#include "sstream"<br />#include "set"<br />#include "queue"<br />#include "stack"<br />#include "fstream"<br />#include "iomanip"<br />#include "bitset"<br />#include "list"<br />#include "ctime"<br />using namespace std;<br />
