我使用的快读快写:
#define LOCAL
using namespace std;
namespace ly {
namespace IO {
#ifndef LOCAL
constexpr auto maxn = 1 << 20;
char in[maxn], out[maxn], *p1 = in, *p2 = in, *p3 = out;
#define getchar() (p1==p2&&(p2=(p1=in)+fread(in,1,maxn,stdin),p1==p2)?EOF:*p1++)
#define flush() (fwrite(out,1,p3-out,stdout))
#define putchar(x) (p3==out+maxn&&(flush(),p3=out),*p3++=(x))
class Flush {
public:
~Flush() {
flush();
}
} _;
#endif
namespace usr {
template<typename type>
inline type read(type &x) {
x = 0;
bool flag(0);
char ch = getchar();
while (!isdigit(ch)) flag ^= ch == '-', ch = getchar();
while (isdigit(ch)) x = (x << 1) + (x << 3) + (ch ^ 48), ch = getchar();
return flag ? x = -x : x;
}
template<typename type>
inline void write(type x) {
x < 0 ? x = -x, putchar('-') : 0;
static short Stack[50], top(0);
do Stack[++top] = x % 10, x /= 10;
while (x);
while (top) putchar(Stack[top--] | 48);
}
inline char read(char &x) {
do x = getchar();
while (isspace(x));
return x;
}
inline char write(const char &x) {
return putchar(x);
}
inline void read(char *x) {
static char ch;
read(ch);
do *(x++) = ch;
while (!isspace(ch = getchar()) && ~ch);
}
template<typename type>inline void write(type *x) {
while (*x)putchar(*(x++));
}
inline void read(string &x) {
static char ch;
read(ch), x.clear();
do x += ch;
while (!isspace(ch = getchar()) && ~ch);
}
inline void write(const string &x) {
for (int i = 0, len = x.length(); i < len; ++i)putchar(x[i]);
}
template<typename type, typename...T>inline void read(type &x, T&...y) {
read(x), read(y...);
}
template<typename type, typename...T>
inline void write(const type &x, const T&...y) {
write(x), putchar(' '), write(y...), sizeof...(y) ^ 1 ? 0 : putchar('\n');
}
template<typename type>
inline void put(const type &x, bool flag = 1) {
write(x), flag ? putchar('\n') : putchar(' ');
}
}
#ifndef LOCAL
#undef getchar
#undef flush
#undef putchar
#endif
} using namespace IO::usr;
} using namespace ly::IO::usr;
之后使用read()
来快读write()
来块写
(()
内随便变量个数、类型(浮点数不行))
可以
read(int_var,char_var);
read(ULL_var);
write('a',int_var,ULL_var,char_var)

太超纲了,不适合蒟蒻食用,还是我的更适合中国蒟蒻体质
