Hey everyone!

I’ve been thinking—wouldn’t it be awesome if Codeforces added a Head-to-Head (H2H) Battle Mode?

Instead of the usual contests, this mode would let two users go 1v1, solving the same problem. How it could work: - You challenge a friend or get matched randomly. - Both players choose a difficulty level and they are given one problem at that difficulty.

Now, part of the inspiration came from TikTok.

If you’ve ever seen multo_tiko, you know how wild those TikTok H2H battles can get. He was insanely competitive—and honestly, I want all of us to be that fired up when we code. Bringing that kind of energy into Codeforces could make training and battling even more fun.

Hello Codeforces. Like last year's blog I wanted to make a list of IZhO participants, can you share their Codeforces handles and their country that you know?

Thank You!

Hello, Codeforces community!

As someone eagerly preparing for the International Zhautykov Olympiad (IZhO) 2025, I’m wondering if anyone has heard any updates regarding its status. Will it happen as planned? Are there any hints from the organizers or past participants?

If anyone has any information—official or even credible rumors—please share! It would mean a lot to those of us preparing for this event.

Looking forward to hearing from you all!

UPD: IZhO will take place from january 13 to january 17 in Astana, good luck!
