When preparing a tournament, Codeforces coordinators try treir best to make the first problem as easy as possible. This time the coordinator had chosen some problem and askednn people about their opinions. Each person answered whether this problem is easy or hard. If at least one of thesenn ...

Problem Solving and Contest Solutions...This repository contains my solutions to various problems from Codeforces contests. Each solution is implemented in C++ and includes a brief explanation of the approach used to solve the problem. The repository is organized by problem number and contest, making...
Also, given the subtree sizes on the rooting at node 1 of each tree, we can compute subiu(v)subiu(v) in O(1)O(1) using simple math if uu and vv are neighbors (it's either the same subtree size or N minus that plus one). Subtask 5 Now the previous solution is O(N2)O(N2)...

AlphaCode generates up to a million samples for each Codeforces problem. Samples are filtered based on their performance on visible test cases. Samples that fail the test cases are discarded. Organizes samples into clusters based on their outputs for custom test cases. ...
Codeforces benchmarks better reflect LLMs' algorithmic problem-solving skills. OpenAI tested o1 and o3 models on Codeforces problems and shared detailed results (1, 2), while other competitors did not. That made a direct comparison impossible. This led to the creation of a new benchmark, allow...
https://codeforces.com/contest/1215/submission/60611022 Here's a problem and Um_nik's solution to it. I was thinking about a lot of things, tried DP etc. and was unable to solve it. Then I saw this crazily concise solution of Um_nik. Can someone explain, what's his approach? Like...
I can also do something like what vjudge does, execute the problem in the respective sites and then scrape the submissions page to fetch the result. But it's kind of an unstable solution, as I'll have to update the whole process of scraping whenever the respective site updates their site...
