This is the first ARC after the change of admin. (See details)

• The criteria for scoring have been revised.
• The difficulty of the later problems is lower than before.

However, due to special circumstances, the difficulty of the earlier problems has significantly increased compared to the standard difficulty target for ARC under the new admin. In the future, the earlier problems in ARC are expected to be easier than this one.

Given the even distribution of difficulty, we recommend reading all problems rather than focusing solely on solving them in order.

We are looking forward to your participation!
