解题思路: 本题在给定的集合中找到最大的子集合[子集合:集合的元素的总和,是所有子集合中的最大解.] 结果输出: 最大的子集合的所有元素的和,子集合在集合中的范围区间. 依次对元素相加,存到一个 sum 中,同时ans=sum;定义左右边界 left,right;临时左边界ll=1; 如果sum>ans,则ans=sum; 左边界 left=tem; right=i+1; 如果sum<0,则sum=0; tem=i+2; Ac code: #include<bits/stdc++.h&g…

HDU 1003    相关链接   HDU 1231题解 题目大意:给定序列个数n及n个数,求该序列的最大连续子序列的和,要求输出最大连续子序列的和以及子序列的首位位置 解题思路:经典DP,可以定义dp[i]表示以a[i]为结尾的子序列的和的最大值,因而最大连续子序列及为dp数组中的最大值.   状态转移方程:dp[1] = a[1]; //以a[1]为结尾的子序列只有a[1]:  i >= 2时, dp[i] = max( dp[i-1]+a[i],  a[i] ); dp[i-1]+a[i…

HDOJ(HDU).1003 Max Sum (DP) 点我挑战题目 算法学习-–动态规划初探 题意分析 给出一段数字序列,求出最大连续子段和.典型的动态规划问题. 用数组a表示存储的数字序列,sum表示当前子段和,maxsum表示最大子段和.不妨设想:当sum为负数的时候: 1.当下一个数字a[i]为正数的时候,sum+a[i] < a[i],不如将sum归零重新计算 2.当下一个数字为负数的时候,sum+a[i]< 0 ,若再下一个数字还为负数,依旧可以得出和小于零--直到遇到一个正数,此…
