传送门 首先(想了很久之后)注意到一个性质:同一条边有多种颜色的话保留3种就可以了,这是因为假如最优解要求当前位置与相邻两条边都不相同,那么只要有3条边,就肯定可以满足这一点. 完事就做一个nlogn*3^4的倍增dp就行了……实际肯定是跑不满的(而且cc机子快). #include<cstdio> #include<cstring> #include<algorithm> #define MN 510000 using namespace std; ],_F[MN][…

传送门 好久没写题解了,就过来水两篇. 对于每一个人,考虑一个序列$A$,$A_I$表示当k取值为 i 时的答案. 如果说有两个人,我们可以把$(A+B)^k$二项式展开,这样就发现把两个人合并起来的操作就是一次卷积,直接NTT就可以了. 同类人有多个,直接暴力肯定是不行的.快速幂的话不知道会不会T,我是用了多项式取ln和exp(拉板子). #include<cmath> #include<cstdio> #include<cstring> #include<al…
