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. -23 _AA_AA_ 5 years ago 1 Comments (1) ...
Today I wanted to solve this problem:Heavy IntervalsBut I gotTLE3code:260013398. that's why I changed the code a little bit and my code(260014069) was correct. But I don't understand how? Can you explain? Here are the differences between my first and second codes...
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...
Note:The goal of competitive programming is to write programs that can be run quickly and compute the correct answer. Maintainability of code is not a core requirement as the code only needs to be readable during the contest. However, it’s ideal to maintain a bare minimum level of readabili...
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, ...
简单构造,推了一会就推出来了,无法理解为啥有2500分,感觉还不如一些1900的题( #include <bits/stdc++.h>usingnamespacestd;intmain() {intt; scanf("%d", &t);while(t--) {intn; scanf("%d", &n);longlongans =0;for(inti =1; i <= (n +1) /2; i++) ...
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...

Hello Codeforces Community, I have recently turned expert in the previous educational round. And now seek advice on how to conquer the next step — Turning Purple I have solved lots of questions in the 1400 to 1500 range which helped me in consistently solving A B and C in almost every Di...
