快读：

inline int read() {
	register int x = 0, f = 1;
	register char c = getchar();
	while (!isdigit(c)) {
		if (c == '-')
			f = -1;
		c = getchar();
	}
	while (isdigit(c)) {
		x = (x << 1) + (x << 3) - (c ^ 48);
		c = getchar();
	}
	return x * f;
}

快写：

inline void write(int x) {
	if (x < 0) {
		putchar('-');
		x = -x;
	}
	if (x > 9)
		write(x / 10);
	putchar(x % 10 + '0');
}

$Windows$ 中还有更优的快读快写模板吗（别提 $Linux$）？
