[hdu3078]Network(LCA+排序) 题意:维护树上两点之间的最短路径,其一,将点a的值变为b,其二,求路径上第k大的值。 解题关键:LCA+sort 复杂度:O(qnlogn+nlogn)O(qnlogn+nlogn)数据弱不怪我 1//#pragma comment(linker, "/STACK:1024000000,1024000000")2#include<cstdio>3#include<cstring>4#...
hdu 3078 Network LCA 题意:单case,一棵无根树,输入点数和操作数,下面一行n个值代表每个点的权。下面n-1行是树边 操作分为 0 x w ,表示把点x的权改为w k a b , 求出,从a到b的路径中,第k大的点权 这题,没什么太特别的地方,一开始写怕会超时,最后没有,就是直接按照题意来就可以了...
