char k1[15],k2[15];


while(scanf("%d",&num)==1 && num!=0){
c=0;
for(i=0;i<10;i++){
ara=k;
k++;
}
while(c!=1){
scanf("%d",&num);
scanf("%s%s",&k1,&k2);
if(strcmp(k1,"too")==0 && strcmp(k2,"high")==0){
for(i=num;i<10;i++) ara=1;
c=0;
}
else if(strcmp(k1,"too")==0 && strcmp(k2,"low")==0){
for(i=num;i>0;i--) ara=1;
c=0;
}
/*if(strcmp(k1,"right")==0 && strcmp(k2,"on")==0)*/
else{
c=1;
if(ara[num]!=1) printf("Stan may be honest\n");

        sscanf(buff, "%d", &d);

        if(!d)
