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...
Now the network is on trial, and new photonic crystal fibers designed by ALPC42 is trying out, the lag on fibers can be ignored. That means, lag happened when message transport through the router. ALPC42 is trying to change routers to make the network faster, now he want to know that...
