Luckily, LeetCode is only showing code submissions from Chinese users on the contest leaderboard. And guess what? similarity.in found that a bunch of LeetCode CN users are simply copy-pasting codes.

Cheating in live contests is getting out of hand, and it’s frustrating for those who put in real effort. To tackle this, we launched Similarity, a platform that detects and flags identical or highly similar code submissions.

In just 24 hours, we received 9000+ website visits, showing how big of an issue this is in the community!

We’d love for LeetCode redditors to try out the platform and share their experience. Any suggestions, feedback, or thoughts—positive or negative—are highly appreciated!

Check out my LinkedIn post about the project:

Let’s work together to bring fairness back to LeetCode contests!

Hi community, I've built a website for checking code plagiarism for live contest on leetcode.

Would really appreciate if codeforces community could check the website and let me know about your thoughts regarding the same.

take a look and let me know!!!

I wanted to know how much time does it take for the 3 regions in India -> Amritapuri, Chennai and Kanpur to declare the official standings and list of all the selected teams for the respective region? Poeple who have previously participated in ICPC, what sort of rank would be required to qualify in the 3 regions for the onsite round? A rough idea would be enough.

So I was solving the question https://codeforces.me/contest/1809/problem/B

While submitting I found that using #pragma GCC target("avx,avx2,fma") in giving WA 292802920 check line 4

while this code 292803134 is giving AC when I am not using #pragma GCC target("avx,avx2,fma")

So why is #pragma GCC target("avx,avx2,fma") this casuing issue? As far as I knew, using this the compiler would optimize the code for CPU utilization. But in this code the while using sqrt() function this is giving WA.

Any reason to explain the same???

Can anyone share a set of problems to practice PBDS on Codeforces? I found tutorial videos on the topic, but I couldn’t find relevant questions to implement and learn from them.
