输入输出外挂

遇到卡时间比较死的题目的时候可以用

#include <iostream>
#include <cstdio>
#include <cstring>
#include <algorithm>
#include <string>

using namespace std;

//适用于正负整形数

template <class T>
inline bool scan_d(T &ret)
{
	char c; int sgn;
	if (c = getchar(), c == EOF) return 0; //EOF
	while (c != '-' && (c<'0' || c>'9')) c = getchar();
	sgn = (c == '-') ? -1 : 1;
	ret = (c == '-') ? 0 : (c - '0');
	while (c = getchar(), c >= '0'&&c <= '9') ret = ret * 10 + (c - '0');
	ret *= sgn;
	return 1;
}

inline void out(long long x)
{
	if (x > 9)out(x / 10);
	putchar(x%10+'0');
}

int main()
{
	int n;long long p[100];
	scanf("%d",&n);
	for (int i = 0; i < n; i++)
		scan_d(p[i]);
	for (int i = 0; i < n; i++)
	{
		out(p[i]);
		printf("\n");
	}
	return 0;
}
