#include <cstring>
using namespace std;

int main() {
int t, r, c, flag;
char a[105][105], e;
scanf("%d", &t);
while(t--) {
memset(a, 0, sizeof(a));

for(int i=0; i<r; i++) {
for(int j=0; j<c; j++) scanf("%c", &a[i][j]);

flag=1;
break;
}
}
}
if(flag) printf("There is a spoon!\n");
else printf("There is indeed no spoon!\n");
}
return 0;
}

note: read the input char after r, c, and also read the char after every line of input(scanf("%c", &e);)
