I think very rarely it happens that the questions asked on the codeforces contests are available on google. But today's contest was a blunder in that aspect. As you must have already seen in the comments of the announcement blog that problems B, C, and D were available on the internet. Now someone will say that even in ICPC you are allowed to copy from the net. You are allowed because you can copy some templates but you won't get direct solutions coz questions are unique. I don't have any issue with geometry problems and no one should have because we are here to learn cp and cp also includes geometry problems. But I believe that duplicacy of questions should never be promoted on codeforces and therefore today's contest is one of the very rare bad contests on codeforces platform. Sorry if it hurts anyone :(
