#include <iostream>
#include <algorithm>
#include <cstdio>
using namespace std;
int n,q,a[1000],b[1000];
int main (){
	while(1){
		cin>>n>>q;
		if(n==0&&q==0)
			return 0;
		for(register int i=1;i<=n;i++)
			cin>>a[i];
		sort(a+1,a+1+n);
		for(register int i=1;i<=q;i++)
			cin>>b[i];
		printf("CASE# %d:\n",q);
		for(register int i=1;i<=q;i++){
			bool vis=0;
			for(register int j=1;j<=n;j++){
				if(a[j]==b[i]){
					vis=1;
					printf("%d found at %d\n",b[i],j);
					break;
				}
			}
			if(!vis){
				printf("%d not found\n",b[i]);
			}
		}
	}
	return 0;
