CCF_201912-1 报数（C++_模拟）

思路

代码可能写的有点啰嗦冗余，写的时候有点急写完一节就直接复制粘贴了蛤蛤蛤，所以导致中间有些代码比较重复。

Code

#include<bits/stdc++.h>//模拟
using namespace std;
int n, sum = 0, a, b, c, d;

bool judge(int s)
{
	int temp = s;
	if (temp % 7 == 0)
		return 0;
	while (temp >= 1)
	{
		if (temp % 10 == 7)
			return 0;
		temp /= 10;
	}
	return 1;
}
int main()
{
	cin >> n;
	for (int i=1;1;i++)
	{
		if (sum == n)
			break;
		if (judge(i))
			sum++;
		else
			a++;
		i++;
		if (sum == n)
			break;
		if (judge(i))
			sum++;
		else
			b++;
		if (sum == n)
			break;
		i++;
		if (judge(i))
			sum++;
		else
			c++;
		if (sum == n)
			break;
		i++;
		if (judge(i))
			sum++;
		else
			d++;
		if (sum == n)
			break;
	}
	cout << a << endl << b << endl << c << endl << d << endl;
	return 0;
}
