so I decided to write a blog that has all important information about how to use Codeforces in a single place. I will update it with time, so feel free to write your suggestions/questions in case I missed something and I will be glad to add it to the post!
Feel free to share any ideas/tips/tricks in the comments section below. [UPD] Some of my friends have told me to ask the following questions to guys who have experience at writing system tests at codeforces or any other platform. 1) What do you guys do to ensure the completeness of the...
We can try to construct a eating sequence on the interval. To do that, we need toguessthat the some maximum slime with size m m in the interval can eat everyone else. But if two neighbouring slimes are both maximum, then they cannot eat each other. So we need toguessthat: If the s...

In this work, we leverage LeetCode as a source of diverse programming problems and challenges for our experiment. We prompt ChatGPT with programming problems and challenges of varying topics and difficulty available on the platform. We then submit the solutions generated by ChatGPT to LeetCode to...
Perhaps I might be blind, but if this was some sort of flag, I can't find it on Polygon. Specifically, I want something like this:https://codeforces.com/gym/373765/problem/Bwhere the only allowed "language" is ZIP. I also have other concerns like how to write the checker/do scoring...

in 10 mins, and some in more than an hour) Some say, “Think on a hard problem for 5 hours and enjoy!” No. trust me, Accepting 10 different problems helps more at this stage. I also recommend reviewing other people’s code. Early on, this helps you write more efficient solutions....
How to Approach Problems in Practice Alright, so codeforces seems good. Why only a rating range where you can solve ~30-40% of the time? Shouldn't you be practicing coming up with solutions on your own? Well, like I said earlier, you want to come across as many concepts as quickly ...
If you ask for solutions or hints for some specific problem, be prepared to send a link. There are two reasons for this. I don't want you to help you cheat. Asking for solutions in an ongoing solution is cheating. And some of you may not realize it, but so is all other discussion...
