先附上一份头文件

ZOJ的编译器很不习惯。经常出现编译错误。很多时候是因为缺少头文件

我也懒得记那个函数要用到哪个头文件。常用的都写上就OK了：

 

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