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…

题目链接:hdu 3415 Max Sum of Max-K-sub-sequence 题意: 给你一串形成环的数,让你找一段长度不大于k的子段使得和最大. 题解: 我们先把头和尾拼起来,令前i个数的和为sum[i]. 然后问题变成了求一个max{sum[i]-sum[j]}(i-k<j<i) 意思就是对于每一个sum[i],我们只需要找一个满足条件的最小的sum[j],然后我们就可以用一个单调队列来维护. #include<bits/stdc++.h> #define F(i,a…

虽然这道题看起来和 HDU 1024  Max Sum Plus Plus 看起来很像,可是感觉这道题比1024要简单一些 前面WA了几次,因为我开始把dp[22][maxn]写成dp[maxn][22]了,Orz 看来数组越界不一定会导致程序崩溃,也有可能返回一个错误的结果 dp[i][j]表示前j个数构成前i段所得到的最大值 状态转移方程: dp[i][j] = max{dp[i][j-1],  dp[i-1][j-len[i]] + sum[j] - sum[j-len[i]]} 分别对应…
