int main() {
	// your code goes here
	int t;
	cin>>t;
	while(t--){
	    int n,x;
	    cin>>n>>x;
	    int a[n];
	    int count=0;
	    int z=0;
	    for(int i=1;i<=n;i++){

	    }
	    
	    for(int i=1;i<=n;i++){
	        for(int j=i;j<=n;j++){
	            z=(a[i]&a[j]);
	            if(z==x){
	                count=1;
	                break;
