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…

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…
