题目链接:https://cn.vjudge.net/problem/HDU-1024 题意 给n, m和一个序列,找m个不重叠子串,使这几个子串内元素和的和最大. n<=1e6 例:1 3 1 2 3 答:6 (唯一的子串1 2 3) 思路 先顺便记录一下动态规划的一般解题思路: 原问题->子问题->状态->转移->边界 再顺便记录一下最大值最小化这类问题套路解法: 二分 贪心 不能二分的问题,贪心八九不离十. 一般是AB和BA这两个元素的顺序,不影响前后变化时,直接算目标…

HDU 1024 题目大意:给定m和n以及n个数,求n个数的m个连续子系列的最大值,要求子序列不想交. 解题思路:<1>动态规划,定义状态dp[i][j]表示序列前j个数的i段子序列的值,其中第i个子序列包括a[j], 则max(dp[m][k]),m<=k<=n 即为所求的结果 <2>初始状态: dp[i][0] = 0, dp[0][j] = 0; <3>状态转移: 决策:a[j]自己成为一个子段,还是接在前面一个子段的后面 方程: a[j]直接接在前面…

题意:从一个序列中选出分成不交叉的m段 的最大和 解析 : 题目中 1 <= n <=1000000 所以二维数组是不能用了  所以 要想到简化为一维 dp[i][j]表示以i结尾的前i个数 分成j组的最大和  对于一个数A[i] 我们有两种选择,一是与第(i-1)个数在一组 或者 自成一组  ,所以状态方程就出来了 dp[i][j] = max(dp[i-1][j], max(dp[k][j-1] {k| 1<= k <= i-1} ))+A[i]; max(dp[k][j-1]…
