Codeforces Contest 1213 Codeforces Contest 1213 工作之余随便找几道简单的算法题练练手,权当锻炼思维。 A - Chips Moving 题意陷阱,题目写的很长很玄乎,其实是最简单的逻辑。分奇偶,选最少的一边 #include<iostream>#include<cstdio>using namespace std;typedeflonglongll;typedefunsignedlonglongllu;#defineMAX...
比赛结束后,可以看其他人的代码和全部的样例数据。也可以在该题侧边栏中的"Contest materials",然后单击"Tutorial"或者"Editoral",找到官方题解。 3、玩法 cf的简单题通常不涉及算法 即div2前三题通常不涉及,第四题不经常做不敢说 包括但不限于枚举,模拟之类的、 ...

Monocarp is practicing for a big contest. He plans to solven n problems to make sure he's prepared. Each of these problems has a difficulty level: the first problem has a difficulty level of 1,the second problem has a difficulty level of 2.and so on, until the last (n-th) problem,...
https://codeforces.com/contest/1331/submission/75143837 赛后发现这个偏移量真的得小心选取,因为原题目里面给的是线圈起来的框,不是正经的黑白格子,如果偏移量小于线的宽度就会造成采样错误。 F. Elementary! 标题误导性很大,我和104都被误导为解题与电视剧Elementary有关,遂去wiki搜了一下提供的8个词,发现no组...
有n只蚂蚁,每只蚂蚁从左往右有值1~n,每个蚂蚁距离1cm,所有蚂蚁在一根绳子上,位于绳子的1~n位 置,绳子长度为n+1,共有n+2个位置(举例:有3只蚂蚁,位于1,2,3,则绳子长度为4,即0-1,1-2,2- 3,3-4这四段,共五个点) 然后每个蚂蚁可以向左向右移动,撞到绳子边缘则掉头,否则不掉头走到黑。然后两只蚂...
