http://acm.hdu.edu.cn/showproblem.php?pid=5086 题目大意: 给定一个序列,求这个序列的子序列的和,再求所有子序列总和,这些子序列是连续的.去题目给的第二组数据的 3 1 2 3 这个序列的子序列有 [1].[2].[3].[1.2].[2.3].[1.2.3],这些子序列的和是分别是1.2.3.3.5.6.再将这些和加起来 1+2+3+3+5+6=20这个就是最终的答案. 解题思路: 我们假设n等于5.序列为1.2.3.4.5.然后我们将它们如下排列…

HDURevenge of Segment Tree(第二长的递增子序列) 题目链接 题目大意:这题是求第二长的递增子序列. 解题思路:用n^2的算法来求LIS,可是这里还要记录一下最长的那个序列是否有多种组成方式,假设>= 2, 那么第二长的还是最长的LIS的长度,否则就是LIS - 1: 代码: #include <cstdio> #include <cstring> #include <algorithm> using namespace std; cons…
