Why do you make pretest as weak as Round 700's Div 2 C... I mean seriously? All pretest were under n <= 100. This is not even a mistake.this almost feels like u guys were trying to do some kind of a prank on us. why,why....please give some kind of explanation? To the people coordinating and testing the round. did u try to submit a brute force on it?
this is crazy...what a waste
