Codeforces Round 997 (Div. 2)
By nifeshe, 12 hours ago, In English

Hi, Codeforces!

I'm delighted to invite you to the best/second best/third best round of 2025 so far! Codeforces Round 997 (Div. 2) will be held on Jan/17/2025 17:35 (Moscow time). You will be presented with at least $$$6$$$ and at most $$$6$$$ problems, one of which might be divided into two subtasks, and $$$2$$$ hours to solve them.

Many of you may not believe it, but the problems were authored and written by nifeshe with a great help from maomao90. Moreover, I would like to thank:

The score distribution is as follows: $$$500-1250-1500-2000-2250-(2750+1250)$$$.

I hope you will find a non-empty subset of problems to be interesting. Good luck!

So now the LGM tag isn't even good enough for the "And You for participating!" line. They've trampled all over the meaning of the word legendary.

Hope we can have easier E and F to solve. E and F for last Div.2 are not fit for rated participant(but it has nothing to do with me thinking they are good problems, especially E is interesting), only two can solve E and no one can solve F is abnormal.

I think this is the new shortest official contest blog, beating the previous contest's blog.
