#include <stdio.h>

int main(void)
{
        int i,yes=0;
        int num;
        int a[3]= {0};

        scanf("%d",&num);

                for(i=0;i<5;i++){
                        a[i] = num/10;
                        if(a[i]==9||a[i]%9){
                                yes++;
                                break;
                        }
