/** 题目:Color 链接:https://oj.ejq.me/problem/23 题意:给定一颗树,将树上的点最多染成m种颜色,有些节点不可以染成某些颜色.相邻节点颜色不同.求染色方法数. 思路:树形dp,定义dp[i][j]表示以i为根,i节点染色为j时候的子树的染色方法数. */ #include<bits/stdc++.h> #define LL long long using namespace std; typedef long long ll; ; ll dp[maxn][…
D. Events 线段树区间更新查询区间历史最小值,看似很简单的题意写了两天才写出来. 题意:n个数,Q次操作,每次操作对一个区间[l,r]的数同时加上C,然后输出这段区间的历史最小值. 思路:在线段树区间更新最值查询的基础上再用一个变量表示历史最小值,每次更新只需对当前最小值更新然后用当前最小值更新历史最小值.细节问题很不好处理,可能会有重复多次更新某个区间但是其下的子节点叶节点却没有更新,而是每次重复叠加了一个add值,这样就可能将最小值覆盖.所以我们在pushdown操作的时候应该注意如…
