题目链接: https://vjudge.net/problem/36696/origin 题目大意: 要求从1到m升序排列,点可以随意移动,问最少需要移动多少次, 思路: 动态规划 可以推出转移方程为:dp[i] = max(dp[i], dp[j]) && mp[i] >= mp[j]  dp[i]++; 其中,dp[i]为i位置的序数mi前能保留(也就是不移动)的最大种类数. dp[i]++是因为自己也不能移动自己,得加一. 下面是AC代码: #include <iost…

[链接] 我是链接,点我呀:) [题意] 在这里输入题意 [题解] 原题意等价于:给你一个序列(实数的位置没用!)..你可以改变其中某些元素的位置(插入到某些位置中间. 然后让他变成有序的. (有序的话,相同的数字就连在一起了 那么求出原序列的一个最长上升子序列. 把除了这个子序列之外的数字再分别插入到这个最长上升序列中就可以变成升序了. 这样是执行插入次数最少的做法. 答案就是数组长度减去最长上升子序列的长度了. [代码] #include <bits/stdc++.h> #define L…

给出 N 个植物,每个植物都属于一个品种,共计 m 个品种,分落在不同的位置上(在一个数轴上,而且数轴是无限长度的),保证读入的位置是按照升序读入的. 现在我们可以进行一个操作:取任意一个位置上的植物,移动到任意一个没有植物的位子上去. 问我们最少进行多少次操作,能够使得从左到右,是按照品种升序排列的(1 ~ m)(单调不降),而且每种植物都相邻. Solution 求一下最长非严格上升子序列即可 #include <bits/stdc++.h> using namespace std; in…

C. Magical Boxes 问题相当于求\[2^p \gt \max{a_i \cdot 2^{k_i}},p \gt k_i\] D. Greenhouse Effect \(dp(i,j)\)表示前\(i\)种树种在位置\(j\)之前所需要的最少操作次数. 转移:\[dp(i,j)=\min\{dp(i-1,k)+sum(j)-sum(k)\}\]sum(j)表示从1到j内不为i的个数. 转移可以写成\[dp(i,j)=\min\{dp(i-1,k)-sum(k)\}+sum(j)\]…
