Changing in Question for March Cook Off 2013

May I know why there were some changes in the programming question in the middle of the competition?I was busy solving a question name “End Of The World 2” , I was shock when i realise the changes because that was the time when I wanted to submit my solution .

It was a mistake. The questions you saw earlier were questions from the last Cook-Off, so CodeChef had to take those down and put up the actual problems for this contest.

OMG , so i’ve spend so much time on it
