The outputs of two consecutive cases will be separated by a blank line. You are both printing too many blank lines.

The last code that you posted isn't printing a newline char at the end of the last line. You are printing: "yes\n\nyes"

Now you're printing too many blank lines.
Remove line 12: cout << endl;
Change line 27 to: if(i!=0) cout<<endl;

Still no luck..! :( :(
I've removed the 12th line and also changed the 27th line as you said.
by the way, the question said that there has to be blank line between each input. I think removing the 12th line won't satisfy that condition...
