LuoguCF362B Petya and Staircases 题解
分析 简单排序题。 首先 Petya 可以通过跨过一个台阶和两个台阶保证不经过脏台阶，但是不可以通过跨过三个台阶来保证不经过脏台阶，所以只要看有没有连续的三个脏台阶即可。 同时，如果第一个台阶和最后一个台阶至少一个是脏台阶那么就不可以达成。 Accepted Code /*Code By Manip ......
[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 ......

CF557D D. Vitaly and Cycle
小清新分类讨论题 首先不难发现这题加边的上界就是\(3\)，并且只有当图中一条边没有时才会取得，方案数就是\(C_n^3\) 而一条边不加的情况也很容易，可以先跑个染色看下有没有奇环，如果有的话就直接输出即可 而加两条边的情况也比较简单，当图中都是孤立边和孤立点时（即所有点度数均\(\le 1\)） ......

[题解]CF514D R2D2 and Droid Army
思路 首先，可以转化题意，找到一个极长的区间 \([l,r]\) 使得（其中 \(mx_i\) 表示 \([l,r]\) 区间中属性 \(i\) 的最大值）： \[\sum_{i = 1}^{m}mx_i \leq k \]显然对于这个东西当 \(l,r\) 发生移动时，是极其好维护的，所以想到双指 ......
