		cout<<"("<<i<<","<<q<<")"<<" ";
	}
	cout<<endl;
	for(int q=1;q<=n;q++){
		cout<<"("<<q<<","<<j<<")"<<" ";
	}
	cout<<endl;
	for(int q=1;q<=n;q++){
		for(int w=1;w<=n;w++){
			if(q-w==i-j) cout<<"("<<q<<","<<w<<")"<<" ";
		} 
	}
	cout<<endl;
	for(int q=1;q<=n;q++){
		for(int w=1;w<=n;w++){
			if(q+w==i+j) cout<<"("<<q<<","<<w<<")"<<" ";
