hi, i'm university student in South Korea.

Nowadays, I have a difficulty to solve one problem.
I've tried the problem of no. 3405 for dozens of times.
I've googled the dataset of the problem and tested it by both my hand and my code. Finally, I can check that there's an error within the accuracy of 10-4 as the problem requires.

If you don't mind, can I get the dataset of the problem no 3405?
I can't find the original dataset because the contest(Northeastern Europe 2001, Western Subregion) is too old, which the problem is given. My e-mail is "iriszero5@gmail.com".

I hope I can get a quick response for this request. Thanks for reading.
