I can't figure out a way to unblock 1713D - Отсчет турнира. I used some wrappers over Console
for easier testing, but even with pure Console
usage it gets stuck on test 3: 167411234.
I do:
Console.WriteLine("? 1 2");
Console.Out.Flush();
And perform all reads by Console.ReadLine()
only.
What can be the reason for this?
