样例正确

#include <bits/stdc++.h>
using namespace std;
int main()
{
	string s;
	int sum=0;
	cin>>s;
	if(s[7]<='Z'&&s[7]>='A'&&s[0]<='Z'&&s[0]>='A'&&s.size()==8)
	{
		cout<<"Yes"<<endl;
		return 0;
	}
	for(int i=2;i<=s.size()-2;i++)
	{
		if(s[1]!=0&&s[i]<=9)
		{
			sum++;
		}
	}
	if(sum==6)
	{
		cout<<"Yes"<<endl;
	}
	else
		cout<<"No"<<endl;
	return 0;
}
