Tournament Problem

http://www.z-trening.com/new/www/html/tasks.php?show_task=5000000228

Mi solution passes all tests except the first one, and I have seen some people don't pass the first test either. What is it? Is it a tricky case?

Mi code: http://www.z-trening.com/new/www/html/submit.php?submit=7100018801&subm_code=1

Here is the input for that case:

2 1
1 
2

Could you post input for the second test for tournament?
