	    cout << "Unable to open file: "<<Name;
        exit(1); // terminate with error
    }
	else
	{
		while(infile >> x)
		{
			string str; // a variable of str data type
			stringstream ss;  
		  	ss<< x;  ss >> str;  	
		  	Sum=0;
		  	for(int r=0;r<str.length();r++) Sum = Sum + str[r]-str[0];
		  	if(Sum==0) cout<<x<<endl;
		}
		infile.close();
