Hello community, I saw a contest named Codeforces Round X in the upcoming contest list, can anybody tell what is that??? If it is a new type of round then I am really excited for it.

codeforces 1474 E - What Is It? (构造) 题目链接:https://codeforces.com/contest/1474/problem/E开始以为答案是 12+22+...+(n−1)212+22+...+(n−1)2 看题解以后发现没有这么简单。。因为每次交换必定会让一个位置还原,所以每个位置都要尽量和当前没有还原位置中的最远的位置交换, 也就是把...

To kickstart your journey in competitive programming, start by learning a programming language of your choice. Then dive into algorithms and data structures. Practice solving problems on platforms like Codeforces, Topcoder, or LeetCode. Join online communities or participate in contests to gain experi...
OpenAI o3is our most powerful reasoning model that pushes the frontier acrosscoding, math, science, visual perception, and more. It sets a new SOTA on benchmarks including Codeforces, SWE-bench (without building a custom model-specific scaffold), and MMMU. It’s ideal for complex queries req...
The CodeContests dataset, derived from platforms like Codeforces, allows for rigorous testing of models on complex coding challenges typically characterized by detailed problem descriptions. This dataset facilitates comprehensive code evaluation using a substantial set of over 200 unseen tests per problem, ...
传送门:https://codeforces.com/problemset/problem/1474/E 显然是道构造题 显然我们考虑反向 由一个 identity permutation 回推至最初的数列 考虑贡献 最大为 n-1 显然只能出现一次这样的操作 再考虑 n-2 发现至多两次 以此类推 就很好构造出一组解 #include <bits/stdc++.h> using namespace std; #define...
The situation is similar on the competitive coding platform Codeforces. GPT-4o only scores in the 11th percentile, while the full o1 model scores in the 89th percentile. The story is largely the same with o3-mini. On various benchmarks, o3-mini with low reasoning effort matches or exceeds...
You all know the Dirichlet principle, the point of which is that ifnboxes have no less thann + 1items, that leads to the existence of a box in which there are at least two items. Having heard of that principle, but having not mastered the technique of logical thinking, 8 year old...
