这么水的题，我竟然WA了一次。。。

#include<stdio.h>
#include<string.h>
#include<algorithm>
using namespace std;
int main()
{
	char s[110];
	while(gets(s))
	{
		int l=strlen(s);
		int sum=0;
		for(int i=0;i<l;i++)
		{
			sum+=s[i]-'0';
		}
		if(sum%3==0)
		{
			printf("YES\n");
			continue;
		}
		else if((s[l-1]-'0')%2==0)
		{
			printf("YES\n");
			continue;
		}
		else if((s[l-1]-'0')==5)
		{
			printf("YES\n");
			continue;
		}
		else 
		printf("NO\n");
	}
	return 0;
