题意:求有长为m的序列生成的长度为n的序列的上升子序列的个数 思路:生成完长为n的序列后,首先我们想到(nlogn)的求上升序列的方法,然后再这个基础上改进,每插入一个的时候,我们可以得到左边的小于它的个数,然后我们就可以得新增加的上升子序列是sum(id-1)+1,然后更新树状数组 #include <iostream>#include <cstdio>#include <cstri

[LeetCode] 300. Longest Increasing Subsequence @ python

一.题目: 给一个数组,求它的最长递增子序列(不要求连续)的长度. 二.解题思路: 动态规划问题.dp[i]表示以nums[i]结尾的递增子序列的长度.需要用到双重循环. 代码如下: class Solution(object):def lengthOfLIS(self, nums):""":type nums: List[int]:rtype: int"""if nums==[]:return

题目 给定一个未经排序的整数数组,找到最长且 连续递增的子序列,并返回该序列的长度。 连续递增的子序列 可以由两个下标 l 和 r(l < r)确定,如果对于每个 l <= i < r,都有 nums[i] < nums[i + 1] ,那么子序列 [nums[l], nums[l + 1], …, nums[r - 1], nums[r]] 就是连续递增子序列。 示例 1: 输入:nums =
