Minimum Swaps To Make Sequences Increasing

首先这道题为什么可以用dp?后面的状态不会影响前面的，好像有个名词叫nonaftereffect什么的，可能我记错了。这个还是比较直接的，我们不知道要不要swap,那索性两种状态都记录一下。dp可以用来求最小值，所以比较适合动态规划。时间复杂度是O(N),空间复杂度是O(N),可优化成O(1)的空间。publicintminSwap(int[]A,int[]B){int[][]dp=newint[

最长上升子序列(Longest Increasing Subsequence)

LeetCode.jpg300.最长上升子序列300.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)
