Below is my solution for Power Arrangers problem of Code Jam 2019 Round 1C.
When I run this solution with Python interactive tool, It indicates as correct
answer. But, Judge gives me as Wrong Answer. I know there is small mistake that
I need to append null character before printing the answer string. But, without
it also, It works fine. Can anyone please explain me the reason why Judge gives
Wrong Answer though interactive tool indicates the solution as correct answer?
