Hey everyone,

While I respect everyone's goals and aspirations, I would kindly suggest refraining from frequently posting daily progress reports in the Recent Actions section. I understand the excitement of sharing accomplishments, but an excessive number of such posts can clutter the feed and potentially overshadow valuable content that could benefit the community's collective learning and growth.

The Recent Actions section is a valuable resource for sharing quality content, insightful discussions, and educational materials that can help us all improve our problem-solving skills and expand our knowledge. By keeping the section focused on such content, we can ensure that valuable information is not buried beneath an influx of progress reports.

Please do not take this as a criticism of your efforts or achievements. On the contrary, I commend your dedication and hard work, and I sincerely hope that you all reach your desired ratings. However, I would encourage you to channel that energy into solving more problems and engaging in meaningful discussions that can benefit the whole community.

Thanks for understanding!

NOTE- I respect every author and Mike for conducting the ERs; their efforts are immeasurable. Still, there are a few common requests or opinions from the community which I would like to convey.

From the past few contests, I usually feel(and see comments) from the past few contests that the ERs are Speedforces or unbalanced. The typical essence of an ER is lost, and the ERs nowadays are more of a standard CF round. Also, the significant error in today's contest affected many contestants' performance.

Why are there no testers for the ERs, unlike the Normal Codeforces Div1/2 Rounds?

Testers can provide valuable feedback and point out the errors that went unnoticed by the authors, like "author solution was wrong", "examples answers were wrong", "we had a mistake in the statement", etc. It can also help in increasing the quality of the problems.

I request the authors and Mike to communicate on this and decide the best for the community.

Thanks!

I know it is not the right place to write this! But if your life has come down to the point where you(people who celebrate Diwali) are still staring at code forces like a nerd while everyone is celebrating. Welcome to the "no-life" club.

Hello, community!

Recently, not my friend xypnx posted a blog about with a Title- IMP: Sharing screenshots of code from the room during contests where he posted that

I discovered that people are now sharing other people's codes who are in their room since, after locking, we can see other people's solutions. Those screenshots were circulated in Discord groups.

Cool, he helped the community.

But wait, how did he know about the discord community since he posted a screenshot of a message from the discord group? Was he a part of the group? Secondly, I saw his recent submissions from CF Round #824 and found out that his submissions were similar to those of the leaked ones.

Proof- Compare his submissions for Problem C and D from the solution in this link

One interesting question, how can someone code Problem D in python when he always coded in CPP? His only submission in Python/Pypy is yesterday's D which was leaked on the Discord channel.

When I commented the same thing on his blog, he deleted it xD.

xypnx Please answer. Thanks!

UPD: All his solutions are skipped.

Today when I logged in to my CodeChef account and looked for the upcoming contests, Cook-off had been removed and was not visible. If anyone has an update, do let us know!

Thanks

Hello Coders!

I was doing this question High School: Become Human. I had to calculate x^y and y^x and take log on both sides...x(logy) and y(logx). When I submitted my solution, it got WA on TC3...where the TC was n=6 and m=6. The answer should be '=,' but the compiler showed '<'...Code in C++17 WA on 3. So why does 6(log6) != 6(log6), according to C++17, when I submitted the code for checking the value of 6log6 in this TC. It surprised me coz now the answer was showing '='... Code in C++17 for checking. But it got failed due to the value of n1 and m1 displayed. When I tried submitting the first code using C++20, it was accepted. AC on C++20.

I tried using Long double also, but it was of no use. https://codeforces.com/contest/987/submission/140238196

Can you somehow tell me why log, C++17, and C++20 behave in this strange manner and give weird output? I don't know why people are downvoting this, but if someone has the answer, do answer this.

Thanks!
