rt（这题答案为什么是0）

#include<bits/stdc++.h>
using namespace std;
int n,s = 0;
char w;
int main()
{
	scanf("%d%c",&n,&w);
	if(w == 'y')
	{
		s = s + 5;
		printf("%d",s);
	}
	if(n <= 1000)
	{
		s = s + 8;
	}
	else
	{
		s = s + 8;
		n = n - 1000;
		while(n != 0)
		{
			s = s + 4;
			n = n - 500;
		}
	}
	printf("%d",n);
	return 0;
}
