  { scanf("%c%s",&c,s);

    for(i=0; s[i]; i++)

      if(s[i]>='A'&&s[i]<='Z'||s[i]>='a'&&s[i]<='z')

#include<stdio.h>
int main(){
char s,str[50];
scanf("%c",&s);
if(s>='a'&&s<='z'||s>='A'&&s<='Z'){
scanf("%s",&str);
int i=0,bl=1;
while(str[i])if(str[i++]==s){
printf("yes");
bl=0;
break;
}
if(bl)printf("no");
