@MikeMirzayanov I have received the following message from the system. I pasted my code accidentally on ideone and the default settings was set to public in my desktop. I don't know why both of my problems are skipped. Problem A was simple and there was no need of compiler. I used logic and online compiler in B question and the retards giving contest copied my code. I would request you to take back any action on me I would be cautious from next time. Thanks in Advance!!
