UVALive - 2678 Subsequence 推理

题目大意：有n个正整数组成一个序列，给定整数S，求长度最短的连续序列，使它们的和大于等于S解题思路：用一个数组sum记录前n个数的和，这样就可以得到任何一段数字的连续和了，在for一遍，用一个数记录左端点的位置，如果左端点到右端点的数之和大于等于S了，就让左端点位移，如果小于S，就让右端点位移#include#includeusingnamespacestd;#definemaxn100010in

String的substring和subSequence的区别

今天截取字符串的时候，无意中发现了subSequence，并且不小心用上了，呵呵，发现同样能和substring一样截取，效果一模一样。

Longest Increasing Subsequence 最长上升子序列

给定一个无序的整数数组，找到其中最长上升子序列的长度。示例:输入:[10,9,2,5,3,7,101,18]输出:4解释:最长的上升子序列是 [2,3,7,101]，它的长度是4。说明:可能会有多种最长上升子序列的组合，你只需要输出对应的长度即可。你算法的时间复杂度应该为O(n2)。进阶:你能将算法的时间复杂度降低到O(nlogn)吗?思路：这道题参考了博文的思路https://www.cnblo
