[CF938G]Shortest Path Queries(线段树分治,并查集,线性基) 题面 CF 洛谷 题解 吼题啊. 对于每个边,我们用一个\(map\)维护它出现的时间, 发现询问单点,边的出现时间是区间,所以线段树分治. 既然路径最小值就是异或最小值,并且可以不是简单路径, 不难让人想到\(WC2011\)那道最大\(Xor\)路径和. 用一样的套路,我们动态维护一棵生成树,碰到一个非树边, 就把这个环的异或和丢到线性基里面去,这样子直接查就好了. 动态维护生成树直接用并查集就好了,没…

线段树的区间修改 时间限制:10000ms 单点时限:1000ms 内存限制:256MB 描述 对于小Ho表现出的对线段树的理解,小Hi表示挺满意的,但是满意就够了么?于是小Hi将问题改了改,又出给了小Ho: 假设货架上从左到右摆放了N种商品,并且依次标号为1到N,其中标号为i的商品的价格为Pi.小Hi的每次操作分为两种可能,第一种是修改价格--小Hi给出一段区间[L, R]和一个新的价格NewP,所有标号在这段区间中的商品的价格都变成NewP.第二种操作是询问--小Hi给出一段区间[L, R]…
