Finally after a year the Izho 2026 Olympiad has started. I wonder where we can find Day1 standings of Izho 2026 Olympiad.

Thanks for attention!

Upd1: scoreboard for day1

Hi everyone!

After a contest Codeforces Round 1028 (Div. 2), i came up with an issue.

A solution that passed system testing during the contest was resubmitted after the round with no changes at all, and guess what it got WA24 322350733!

This made me wonder:

• were the testcases added after the contest?
• if so, shouldn't all accepted submissions be retested to keep things fair?

It's a bit confusing to see two different verdicts for the same code. If this kind of thing is possible, maybe it would be good to clarify how it's handled officially.

Has anyone seen this happen before?

what happened, why we cant see submissions while hacking phase?

its been a while since last rating rollback?

Wen next rating rollback?

What happened??

How to handle this judge?

it is weird

From March 10th to March 20th, I had the chance to attend a Competitive Programming (CP) camp led by Kamil (kamilszymczak1). Over 10 intense yet fun-filled days, I improved my problem-solving skills, learned new techniques, and bonded with fellow participants. Here's a quick overview of my experience:

Daily Structure: Coding, Learning, and Fun

Each day, we started with a contest from 9:00 AM to 2:00 PM, featuring 3 problems that challenged our programming abilities. After the contest, from 3:00 PM to 5:00 PM, there was an editorial session where participants who scored 100 points on at least one problem explained their solutions. This was a great chance to learn different approaches and earn chocolates for explaining the problem!

In the evenings, we had lectures on algorithms and techniques to help us with the day’s problems. Afterward, we were free to upsolve or practice on Codeforces, or even play sports to unwind. By 9:00 PM, we’d order some fast-foods, usually from KFC or Max-Way, and relax together.

The Last Day: Special Visits and Prizes

On the final day, we visited parks and centers, followed by a meeting with the Minister of Education to discuss the importance of competitive programming. We also explored IT-Park and Uzinfocom, gaining insights into the tech industry. To wrap it up, we were awarded prizes for our efforts during the camp.

Key Takeaways

• Time Management: Learning how to manage time during contests was crucial.

• Collaboration: Sharing solutions in the editorial sessions was a great way to learn from others.

• Industry Insights: Visits to IT-Park and Uzinfocom showed how competitive programming skills can apply in real-world tech jobs.

• Balance: The mix of coding, free time, and fun food moments made the camp an enjoyable experience.

Final Thoughts

The CP camp was a fantastic way to improve my skills and meet other passionate programmers like Timosh. Thanks to Kamil (kamilszymczak1), I now feel more confident in tackling tough problems. If you're looking to boost your competitive programming skills, I highly recommend joining such a camp. It’s a perfect mix of learning and fun!

Hi everyone. I recently started learning Segment Tree. So now I want to solve more problems with Segment Tree in Codeforces. Can you suggest me some problems similar to a Segment Tree, like 896E - Welcome home, Chtholly? So I can improve myself?

Thanks in advance!
