CF367C Sereja and the Arrangement of Numbers
这题首先上来会发现题目中的很多信息都是假的，核心就是问要构造一个\(x\)个点的完全图至少要多长的序列 我们把序列中相邻的两个元素看作图上的一条边，则可以把问题转化为：给一个\(x\)个点的完全图，问至少要走多长的路径才可以遍历图中的所有边至少一次 简单讨论下会发现当\(x\)为奇数时，此时图中每个 ......
[题解]CF1881G Anya and the Mysterious String
思路 发现如果一个字符串中有长度大于等于 \(2\) 回文子串，必定有长度为 \(2\) 的回文子串或长度为 \(3\) 的回文子串，并且形如：aa 和 aba。 所以考虑用线段树这两种情况。维护一段区间的最左、次左、最右、次右的元素，同时用两个标记变量 \(f_1,f_2\) 分别表示这个区间中是 ......
