意甲冠军: 特定n小点的树权. 以下n每一行给出了正确的一点点来表达一个销售点每只鸡价格的格 以下n-1行给出了树的侧 以下Q操作 Q行 u, v, val 从u走v,程中能够买一个鸡腿,然后到后面卖掉,输出max(0, 最大的收益) 然后给[u,v]路径上点点权+=val 思路: 树链剖分裸题.记录区间的最大最小值,→走的答案和←走的答案. 官方题解:点击打开链接 #pragma comment(linker, "/STACK:1024000000,1024000000") #inc…
题目大意: 给出一棵树.每一个点有商店.每一个商店都有一个价格,Yaoge每次从x走到y都能够在一个倒卖商品,从中得取利益.当然,买一顶要在卖之前.可是没次走过一条路,这条路上的全部商品都会添加一个v. 输出每次的最大利益. 思路分析: 非常easy想到树链剖分,但是关键在于怎样维护这样一个变量.使得每次都要让买的再卖的前面. 维护变量 ltr 和 rtl .表示从左去右和从右去左. 剖分熟练的时候.推断x 和 y的深度,一步一步往上爬. 然后维护区间最大值和最小值.爬的时候更新答案. ...4…
题目大意: 给定n (表示树有n个结点) 接下来n行给定n个点的点权(在这个点上买鸡或者卖鸡的价钱就是点权) 接下来n-1行每行给定 x y 表示x结点和y结点之间有一条边 给定q (表示有q个询问) 接下来q行 每行给定 x y v 查询x到y的路径上 先买鸡再卖鸡能够赢得的最大利润 买卖完后 x到y整条路径的点权都要加上v 因为必须先买再卖 所以这个买卖有方向性 就得维护区间 从左向右买卖的最大利润maxl 和 从右向左买卖的最大利润maxr 而 从左向右买卖的利润maxl = 右子区间的最…
