I'm trying to complete Birthday as a part of a group competition. However, the following code results in an error I have no idea on how to resolve:

Here is the code on pastebin, as I can't for the love of God paste the code here in any way...

The code errors out with this message:

wrong output format Unexpected end of file - int32 expected

Not only does the code work OK when I compile it on my PC, it also outputs the valid values (at least for the example queries). How does one fix this?
