[题目]题意:N个城市形成一棵树,相邻城市之间的距离是1,问访问K个城市的最短路程是多少,共有M次询问(1 <= N, M <= 100000, 1 <= K <= N). [思路] 访问K个城市的路线: 可以发现它由一条主线和若干支线构成,并且主线上的边只用访问一次,而支线上的边必须且只用访问两次.而题目给定的是一棵树,那么访问K的城市就必须且仅需要走K-1条边.总边数是固定的,我们只需要保证主线最长即可,所以就是在树中找最长链. [找最长链]树形dp,dp[i]表示他的子树的最…

题目链接 题意:摞长方体,给定长方体的长宽高,个数无限制,可随意翻转,要求下面的长方体的长和宽都大于上面的,都不能相等,问最多能摞多高. 题解:个数无限,其实每种形态最多就用一次,把每种形态都单独算一种,同时保证长比宽大,按dp做即可.注意要从小到大摞,从大到小是不对的. #include <bits/stdc++.h> using namespace std; struct sa { int l,w,h; }data[]; ],n,d[]; bool cmp(sa x,sa y) { if(…
