During the contest i have challenged these two solution 7593695 , 7593010 my test case was 2 1 2 when i challenged their solution it was showing "Invalid Input". but these solution gave wrong answer on the very same cases after system testing What does this mean "Invalid Input"..???
u should have added a newline after the second line of input.
if u had done that, the input format would have been valid, and u would have received Successful hacking attempt.
is enter not a newline?
i have also hacked some codes before but never got this kind of problem.
