Hello,
I have to admit the balance of the problemset of div2 of March cookoff was very terrible, the two problems that I intended to be the easiest two turned out to be difficult to implement.
I have to apologize for everyone who didn’t enjoy the contest because of this. however, I will make sure this will not happen again, as you have noticed from now on only 3 problems will be common between div1 and div2, so I recommend every div2 participant (especially the ones who solved at most 1 problem today) to look forward for future short contests and try to solve at least two problems, because from the March’s lunchtime onwards, the first two problems in the problemset will be really easy!
