#include<iostream>
 
using namespace std;
 
int main()
{
	int x,y,z;
	cout<<"X\tY\tZ\tXY+Z";
	
	for(x=0;x<=1;++x)
		for(y=0;y<=1;++y)
			for(z=0;z<=1;++z)
			{
				if(x*y+z==2)
					cout<<"\n\n"<<x<<"\t"<<y<<"\t"<<z<<"\t1";
				else
					cout<<"\n\n"<<x<<"\t"<<y<<"\t"<<z<<"\t"<<x*y+z;
			}
	
	return 0;
}
